- Plesk for Linux
Is it possible to install Plesk on Ubuntu 20.04?
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.
