Stopping and starting the agent or upgrading manually is no use.

Plesk on Ubuntu 22.04.2 LTS seems unaffected, python version differs

Ubuntu 20.04.6 LTS:
root@plesk52:~# dpkg -l python3 Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==============-==============-============-========================================================================= ii python3 3.8.2-0ubuntu2 amd64 interactive high-level object-oriented language (default python3 version)

Ubuntu 22.04.2 LTS:
root@plesk63:~# dpkg -l python3 Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==============-==============-============-========================================================================= ii python3 3.10.6-1~22.04 amd64 interactive high-level object-oriented language (default python3 version)

Anyone with the same problem?
