How to perform a dist-upgrade?

Warning: The dist-upgrade procedure is not suggested and instead the suggested approach is the migration as can be seen here: Plesk Migration and Transfer Guide

Warning: The dist-upgrade procedure can not be performed in a containerized environment. If this is not known, contact the server provider in order to know if the server or the environment is a container.

The dist-upgrade procedure is supported in Plesk as per the following versions:

Supported for Plesk version
Ubuntu 18 > Ubuntu 20 Plesk Obsidian 18.0.33 and above
Ubuntu 16 > Ubuntu 18 Plesk Obsidian 18.0.30 and above
Debian 9 > Debian 10 Plesk Obsidian 18.0.30 and above
Ubuntu 14 > Ubuntu 16 Plesk 17.8
Debian 8 > Debian 9 Plesk 17.8

If you have never performed dist-upgrade before, it is recommended to test it first as follows:

If you want or need Plesk to assist on this task or to do it on your behalf, it can be requested to Plesk Professional Services team here: Plesk Professional Services: Administrative Services

Ubuntu distributions

Dist-upgrade from Ubuntu 14 to Ubuntu 16

Warning: dist-upgrade from Ubuntu 14 to Ubuntu 16 and is supported by Plesk Onyx 17.8 version.

Warning: During an upgrade from Ubuntu 14 to Ubuntu 16, system PHP 5.x shipped by OS vendor will be upgraded to PHP 7.x. So to avoid any PHP compatibility issues, before an upgrade, it is highly recommended to switch all sites having PHP handler 5x by OS vendor to corresponding custom PHP handlers. Please refer to these KB articles for details: How to configure PHP handlers in Plesk for Linux? and How to apply new PHP handler to multiple domains via CLI?

Warning: Also, MySQL server upgrade can fail during the upgrade. The issue and its resolution are described in: Dist-upgrade from Ubuntu 14 to 16 fails: Sub-process /usr/bin/dpkg returned an error code (1).

Warning: if PHP by OS vendor was updated from third-party sources prior to dist-upgrade, it may break webmail functionality.

  1. Create a full server backup. Before the upgrade, make a full server backup. Also notify the customers about upcoming downtime of one to three hours.

  2. Run below script and follow the wizard:

    # /opt/psa/bin/distupgrade.helper.ubt14-ubt16.x64.sh

    The script logs all its actions in /var/log/plesk/install/plesk-distupgrade.log .

  3. During the script execution you will be asked to reboot the server. Reboot the server.

  4. After the server reboot, run the script once again.

Dist-upgrade from Ubuntu 16 to Ubuntu 18

Warning: dist-upgrade from Ubuntu 16.04 to Ubuntu 18.04 is supported by Plesk Obsidian since 18.0.30 version.

Note: During this procedure, neither MySQL or MariaDB are upgraded. The MariaDB-10.x or MySQL-8 is done at your own will and risk.

Preparing server for upgrade

  1. Create a full server backup. Before the upgrade, make a full server backup. Also notify the customers about upcoming downtime of one to three hours.

  2. Update the current system to the latest available versions:

    # apt-get update && apt-get upgrade

    Note: the dist-upgrade procedure is supported (and has been tested) for Plesk version since 18.0.30

Performing the dist-upgrade

  1. Update source.list file and configure the repository for the OS release that is going to upgrade to:

    # cat /etc/apt/sources.list
    deb http://archive.ubuntu.com/ubuntu bionic main restricted universe
    deb http://archive.ubuntu.com/ubuntu bionic-updates main restricted universe
    deb http://security.ubuntu.com/ubuntu bionic-security main restricted universe multiverse
    deb http://autoinstall.plesk.com/PSA_18.0.31/ bionic all
    deb http://autoinstall.plesk.com/ubuntu/PHP70_17 bionic all
    deb http://autoinstall.plesk.com/PHP71_17/ bionic all
    deb http://autoinstall.plesk.com/PHP72_17/ bionic all
    deb http://autoinstall.plesk.com/PHP73_17/ bionic all
    deb http://autoinstall.plesk.com/PHP74_17/ bionic all
    deb http://autoinstall.plesk.com/debian/SITEBUILDER_17.8.12 all all
    deb [arch=amd64] http://autoinstall.plesk.com/PMM_0.1.11 bionic all
    deb [arch=amd64] http://autoinstall.plesk.com/NODE_0.0.2 all all
    deb https://packages.grafana.com/oss/deb stable main
    deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable

    Note: The example above is for an installed version of Plesk Obsidian 18.0.31. The correct link for each installed version must be modified accordingly.

    For example: http://autoinstall.plesk.com/PSA_x.y.z/ 

    Whereas the version x.y.z is the current Plesk installed version, which can be found in the output of the command:

    # plesk -v

  2. Update the repositories:

    # apt-get update

  3. Upgrade the kernel:

    # apt-get install linux-generic

  4. Reboot the server.

  5. Update dpkg package:

    # apt-get install dpkg

  6. Update apt package:

    # apt-get install apt

  7. Get the Plesk packages that need to be upgraded. It can be done manually from the URL present in the /etc/apt/sources.list.d/plesk.list file.

  8. Upgrade the list of packages, for example:

    # apt-get install plesk-php72 plesk-php73 plesk-php74 plesk-core plesk-core-utilities plesk-backup-utilities pp18.0.31-bootstrapper sw-engine-cli-2.31 libcurl4 plesk-service-node-utilities sw-collectd apache2 awstats psa-drweb-configurator psa-horde psa-imp psa-ingo psa-kronolith psa-mnemo psa-passwd psa-php-configurator psa-proftpd psa-turba libapache2-mod-passenger-plesk passenger plesk-config-troubleshooter plesk-git-http libcgi-fast-perl libcgi-pm-perl libcurses-perl libcurses-ui-perl libencode-locale-perl libfcgi-perl libfile-copy-recursive-perl libhtml-parser-perl libhtml-tagset-perl libhtml-template-perl libhttp-date-perl libhttp-message-perl libio-html-perl liblwp-mediatypes-perl libnet-xwhois-perl libterm-readkey-perl liburi-perl

    Note: If prompted, the /etc/awstats/awstats.conf, if it has not been manually modified, install config made by package maintainers

    Note: When prompted, you should keep previous version of /etc/apache2/apache2.conf

    Warning: after this operation apache2 won't start due to problems with http_proxy module.

    1. Disable it by removing file /etc/apache2/mods-enabled/proxy_http.load

      # rm /etc/apache2/mods-enabled/proxy_http.load

    2. Start apache:

      # systemctl start apache2.service

  9. Upgrade the following packages:

    # apt-get install sw-nginx sw-cp-server plesk-engine plesk-control-panel

  10. Execute the dist-upgrade command:

    # apt-get dist-upgrade

  11. Update Plesk to next available version:

    # plesk installer update

  12. Reboot the server.

  13. Check that Plesk and all its services are working.

Dist-upgrade from Ubuntu 18 to Ubuntu 20

Warning: The dist-upgrade process from Ubuntu 18.04 to Ubuntu 20.04 is supported by Plesk Obsidian 18.0.33 version.

Warning: The dist-upgrade process from Ubuntu 18.04 to Ubuntu 20.04 is supported with MariaDB scenario only.

Preparing server for upgrade

  1. Create a full server backup. Before the upgrade, make a full server backup (which is includes a full backup of all the databases). Also notify the customers about upcoming downtime of one to three hours.

  2. Remote management module must be installed on the server (This is because in some tests, sshd service could not be started during the process)

  3. Connect and perform the process connected as root or by using the # su - or # sudo su -command.

  4. Uninstall unsupported components like docker, PHP below 7.0, Watchdog (Ubuntu users only)... It can be done through Plesk installer.

    Note: More information can be found here: Software Requirements for Plesk Obsidian

  5. Temporary install msmtp copmponent instead of Postfix. It can be done through Plesk installer or by using the command:

    # plesk installer add --components msmtp

  6. Add to the mariadb config file (Usually /etc/mysql/my.cnf) the string innodb_fast_shutdown=0 in the [mysqld] section.

  7. Restart the DB server to apply changes:

    # systemctl stop mariadb.service ; systemctl start mariadb.service

  8. Update the current system to the latest available versions:

    # apt-get update && apt-get upgrade

  9. Remove all plesk-related repos from /etc/apt/sources.list.d/

  10. Stop grafana service:

    # systemctl stop grafana-server.service

Performing the dist-upgrade

  1. Update source.list file and configure the repository for the OS release that is going to upgrade to:

    Note: The example above is for an installed version of Plesk Obsidian 18.0.33. The correct link for each installed version must be modified accordingly.

    For example: http://autoinstall.plesk.com/PSA_x.y.z/ 

    Whereas the version x.y.z is the current Plesk installed version, which can be found in the output of the command:

    # plesk -v

  2. Update the repositories:

    # apt-get update

  3. Upgrade the kernel:

    # apt-get install linux-generic

  4. Update MariaDB to the next major version provided by vendor:

    # apt-get install mariadb-server-10.3

  5. Remove from the mariadb config file (Usually /etc/mysql/my.cnf) the string innodb_fast_shutdown=0 in the [mysqld] section, added at the begining of this process.

  6. Install udev package:

    # apt-get install udev

    Warning: The udev package installation may fail on Ubuntu systems which may be needed to be solved manually. If that is the case, the following should be checked and applied:

    1. At line 26 in the /lib/systemd/system/systemd-udevd.service file, the following string should be changed:

    2. From:

      CONFIG_TEXT: ExecReload=udevadm control --reload --timeout 0

    3. To:

      CONFIG_TEXT: ExecReload=/bin/udevadm control --reload --timeout 0

    4. And execute the following command:

      # apt-get -f install

  7. Install Systemd package:

    # apt-get install systemd

  8. Reboot the server to the new kernel:

    # shutdown -r now

    Note: This will help to avoid problems with services that already loaded old libc6/libstdc libraries

    Warning: MariaDB won't start till the reboot is performed.

  9. Remove packages that were installed by dependencies and not needed anymore:

    # apt-get autoremove

  10. Upgrade packages:

    # apt-get upgrade

    Note: If prompted, choose "latest" for LXD if this is unknown.

    Note: When prompted, you should keep the previous version of Spamassassin configuration file.

  11. Remove packages that were installed by dependencies and not needed anymore:

    # apt-get autoremove

  12. Execute the dist-upgrade command:

    # apt-get dist-upgrade

    Note: At this point, plesk-mail-pc-driver, postfix, drweb, kav packages will be removed because there is already a vendor's Postfix that will be used in Ubuntu 20 (which version is lower that the psa-postfix installed in Ubuntu 18)

  13. Remove packages that were installed by dependencies and not needed anymore:

    # apt-get autoremove

  14. Update Plesk to the next available version finishing the dist-upgrade process:

    # plesk installer update

  15. Check that all the Plesk components are installed and if not (Like for example in case there were components uninstalled like the ones in the dist upgrade step), select and re-install them again through the plesk installer along with Postfix which was replaced by msmtp at the beginning:

    # plesk installer

  16. Reboot the server:

    # shutdown -r now

  17. Check that Plesk and all its services are working.

Debian distributions

Dist-upgrade from Debian 8 to Debian 9

Warning: dist-upgrade from Debian 8 to Debian 9 is supported by Plesk Onyx 17.8 version.

Warning: if PHP by OS vendor was updated from third-party sources prior to dist-upgrade, it may break webmail functionality.

Preparing server for upgrade

  1. Create a full server backup. Before the upgrade, make a full server backup. Also notify the customers about upcoming downtime of one to three hours.

  2. Consider to remove sources list backup files which might be left from the previous dist-upgrade:

    • /etc/apt/sources.list.saved_by_plesk_distupgrade
    • /etc/apt/sources.list.d/50sw_autoinstaller.list.saved_by_plesk_distupgrade`

  3. Run pre-upgrade helper script and prepare Plesk and the system for the upgrade:

    # /opt/psa/bin/distupgrade.helper.deb8-deb9_pre.x64.sh

    The script logs all its actions in /var/log/plesk/install/plesk-distupgrade.log.

Performing the dist-upgrade

  1. Update source.list file and configure repository for the OS release that is going to upgrade to:

    # cat /etc/apt/sources.list
    deb http://deb.debian.org/debian stretch main contrib non-free
    deb http://security.debian.org/debian-security/ stretch/updates main contrib non-free
    deb http://deb.debian.org/debian stretch-updates main contrib non-free

  2. Update information about system packages:

    # apt-get update

  3. Upgrade the system:

    # /opt/psa/bin/distupgrade.helper.deb8-deb9.x64.sh

    This command will perform a complete upgrade of the system, install the newest available versions of all packages and resolve all possible dependency changes between packages in different releases.

    During the upgrade the system might produce prompts like:

    CONFIG_TEXT: Configuration file /etc/mysql/my.cnf
    ==> Modified (by you or by a script) since installation.
    ==> Package distributor has shipped an updated version.
    What would you like to do about it ?
    Your options are:
    Y or I : install the package maintainer's version
    N or O : keep your currently-installed version
    D : show the differences between the versions
    Z : start a shell to examine the situation
    The default action is to keep your current version.
    *** my.cnf (Y/I/N/O/D/Z) [default=N] ?

    Choose to replace configuration files with a new one (answer Y).

Finalizing the upgrade

  1. Run post-upgrade helper script:

    # /opt/psa/bin/distupgrade.helper.deb8-deb9_post.x64.sh

    Note: This script is already called during the execution of /opt/psa/bin/distupgrade.helper.deb8-deb9.x64.sh, run it to verify that everything was successfully done. Its actions are logged in /var/log/plesk/install/plesk-distupgrade.log too.

  2. Reboot the server.

  3. Check that Plesk and all its services are working.

    # apt-get autoremove

  9. Execute the dist-upgrade command:

    # apt-get dist-upgrade

    Note: At this point, there is a possibility that components are removed, like for example: php7.0-curl plesk-mail-pc-driver postfix psa-drweb-configurator psa-spamassassin which is because on Debian 10 vendor's postfix is used and its version is lower than postfix shipped by Plesk for Debian 9

  10. Update Plesk to next available version finishing the dist-upgrade process:

    # plesk installer update

  11. Check that all the Plesk components are installed and if not (Like for example in case there were components uninstalled like the ones in the dist upgrade step), select and re-install them again through the plesk installer along with Postfix which was replaced by msmtp at the beginning:

    # plesk installer

  12. Reboot the server:

    # shutdown -r now

  13. Check that Plesk and all its services are working.

  14. Use the following commands to regenerate web server as well as DNS configuration files if needed:

    # plesk repair web

    # plesk repair dns

Warning: Most of APS application will not work with PHP 7.x

    Unfortunately my vserver hosted by hosteurope does not come online again after running

    # /opt/psa/bin/distupgrade.helper.ubt14-ubt16.x64.sh

    and rebooting after. Although there were no errors.

    Only the pre-installed version and their updates are usable.
    A dist-upgrade attempt will result in a system that is no longer running after a reboot.

    I'm still waiting for the backup process of 300 gigabytes (for 6 hours) to repair this bullshit ... please put a hint right over the call.


    Reason: 
    The virtualization software of hosteurope is probably not compatible with the updated kernel and no longer find the VM.

    Prevent do-release-upgrade to be run directly or at least inject on it a clear warning message requesting confirmation.

    Plesk adds its pretty text to the SSH greeting message, so it should be doable. As per this KB article, you have to run a Plesk script; forgetting that and running do-release-upgrade directly may cause high troubles.

    Updating from Ubuntu 14.04 to Ubuntu 16.04.1 using do-release-upgrade will fail because MySQL is updated from 5.5 to 5.7, that is unsupported update path as per MySQL official documentation. Your script should do these pre-checks and prevent upgrade or automatically solve the issue before the upgrade.

    @Marco, did you check Dist-upgrade potential issues article? Maybe it contains the issue you are talking about and the solution for that.

    @Bulat Tsydenov Yes I do and this is not listed. It seems like a bug, infact running the script as described in this article on a clean Ubuntu 14.04 installation, will upgrade MySQL 5.5 to 5.7 that is an unsupported upgrade. Too, command 'update-alternatives' is not run. This will work only if MySQL was manually upgraded to 5.6 before, but this is not mentioned anywhere.

    Beware after upgrading from Ubuntu 14 to 16, cron jos set to be run with "PHP from OS vendor" won't run anymore, failing with error "/bin/sh: /usr/bin/php5: No such file or directory" because PHP 5 is not available anymore.

    "plesk repair" tool won't regenerate cron jobs.

    You have to fix them manually, just open them one by one from Plesk UI, and hit OK button. This will be enough to regenerate cron files.

    The issue maybe related to the fact that the "Use PHP version" dropdown still shows PHP 5.5.9 from OS vendor after upgrade. This maybe happens because there are residual 5.5.9 packages in the system that wasn't purged during upgrade.

    Please note that after upgrade, MySQL event scheduler won't be enabled again, if it was before the upgrade, and you should fix that manually.

    @Trung, such errors are usually caused by incompatibility of Plesk with repositories that are configured on the server.

    Please, make sure that standard repositories only are configured on the server and restart the script.

    Hi, since Ubuntu 18.04.1 was released a month ago, when the upgrade will be available ?

    + Do you recommend an upgrade or a migration on a fresh install ?

    Thanks

    Hello @Florent, the upgrade will be available soon. There is no exact ETA but this article will be updated with the corresponding information.

    > Do you recommend an upgrade or a migration on a fresh install?

    Both methods are ok and the choice is up to you.

    I attempted today the upgrade from debian 8 to 9 following the above instructions. All went fine (except in the beginning that I had to manually remove some atomicorp repos [1] which were stopping the procedure), until at the end of the dist-upgrade that I got:

    Fetched 76.2 MB in 21s (3472 kB/s)
    Reading package lists...
    Reading package lists...
    Building dependency tree...
    Reading state information...
    E: Unable to locate package psa-php-configurator
    Some error during dist-upgrade middle stage have occurred.
    Check /var/log/plesk/install/plesk-distupgrade.log for error details.
    Visit https://docs.plesk.com/en-US/current/administrator-guide/server-administration/distupgrade-support.74627/ for information about troubleshooting and recovering from failed dist-upgrade.
    STOP Distupgrade

    Just out of curiosity I tried to run the post upgrade script (# /opt/psa/bin/distupgrade.helper.deb8-deb9_post.x64.sh) but there was no such script.

    I rebooted the server, everything looked fine, I entered Plesk and at the home screen I saw:
    Debian 9.8‬
    Product Plesk Onyx
    Version 17.8.11 Update #45

    It looked as if the upgrade had succeeded. But this being a critical server, I could not risk it, so I restored the server from the snapshot I had taken just before.

    So, what happened? Why those errors? Should I try again changing something?

    Hi @Alexandr.

    Thanks for your offer, but I cannot submit a ticket since I'm on a licence key bought from Hetzner, which does not provide free support. And my company is not willing to pay for support on a thing that looks like a plesk bug... It's a deadlock! Can you help otherwise?
