Why install a new ispconfig server on an old Ubuntu version?!? Ubuntu 20.04 is end of life since May this year.
That's probably what is causing install failures for several packages.
At least for php packages, because that repository also dropped Ubuntu 20.04 support.

As ispconfig needs to be installed on an clean base system just reinstall your vps with the latest Ubuntu LTS version, 24.04.
Or upgrade your current version to 24.04. Though reinstalling will be easier and faster.

If you than install ispconfig again there shouldn't be any problems.

 

Ok yeah its showing like this in ssh, now which to upgrade 22.04 or 24.04

Code:

New release '22.04.5 LTS' available.
Run 'do-release-upgrade' to upgrade to it.
