Question
-
Is it possible to install Plesk on Ubuntu 20.04?
Answer
Plesk now supports Ubuntu 20.04 LTS (Focal Fossa) starting from Plesk Obsidian 18.0.29
However, keep in mind the following limitations:
-
Plesk does not support dist-upgrade from any previous versions of Ubuntu. A guide for dist-upgrade from versions 16 to 18 and 18 to 20 will be available on Plesk Obsidian 18.0.31.
-
Plesk installation fails if mysql8 is installed on the server;
- Ubuntu 20.04 ships with OpenSSL which does not support TLSv1.1 and below. Because of that: TLSv1 and TLSv1.1 ciphers cannot be enabled on services via server_pref command;
- psa-watchdog component is not available, since it requires a major update to use TLSv1.2 or higher;
- The following components are deprecated or EOLed by Plesk or their respective vendors: mod_bw ( deprecated ), php <= 7.0 ( EOLed );
- Atomic (tortix) ModSecurity ruleset is not available because Atomic doesn’t support Ubuntu 20.04 yet;
- Time synchronization is not available on Tools & Settings > System Time because Ubuntu 20.04 uses chronyd service (enabled by default) for time synchronization. Same as on CentOS 8 and Debian 10;
- Connection to the server might be interrupted the first time Plesk Firewall rules are activated;
-
There are warning about fail2ban and spamassassin services from systemd in the logs:
CONFIG_TEXT: PIDFile= references path below legacy directory /var/run/
These messages can be ignored.

Plesk does not support dist-upgrade from any previous versions of Ubuntu;
Does this means there is no way to updated from 18.04 lts to 20.04lts ? only via fresh install ?

Yes, currently update via migration to a new server is only available. But it is planned to add in future possibility of dist-upgrade from 18 to 20
Ich bekomme nach der Neuinstallation folgende Meldung:
Hi Anton Maslov,
sorry for the old, stupid question about do release upgrade from Ubuntu 18 to 20. In the top of this site Plesk support says:
A guide for dist-upgrade from versions 16 to 18 and 18 to 20 will be available on Plesk Obsidian 18.0.31.
Now, we have 18.0.31 since a few days, but in change log nothing about dist-upgrade 18 to 20. No problem if Plesk is already working on it, I have respect for the hard work by Plesk all the time. Perhaps, or sometimes, the documentation is only forgotten. That's why I ask.
Lots of greets
Hello Markus
Work on this is still in progress.

According to the Plesk Premium Email extension page, Plesk Premium Email does not support Ubuntu 20.04 yet. It supports the following operating systems:
Wir haben jetzt 18.0.32, wann denkt Ihr, wird das dist-upgrade von Ubuntu 18 auf 20 möglich sein?
Hi!
Has the upgrade process between Ubuntu 18 to Ubuntu 20 been finished? Or is there any estimate when it will be?
Thanks in advance
Any news would be great, when it is planned to have it running.
Hi, Marc please check this article. During testing 18>20 upgrade we found additional items requiring attention, thus it is expected with 18.0.33 release in February.
Great news, thanks a lot for your note and work.
Ubuntu 20.04 now Supported by Atomic?
