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.
