Backup error since upgrading to 9

[Mace68]

Ever since upgrading to 9 I get this email every day. Is this a known issue?

/etc/cron.daily/pvehost-backup:
tar: /etc/sysctl.conf: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors

Is this a known issue?

Maybe.

Did you check if "/etc/sysctl.conf" does (not) actually exist?

The error was generated by tar, called in your "/etc/cron.daily/pvehost-backup". Don't you think it would be a great idea to post that script, to give us a chance to grasp what you are doing?

It used to belong to the package "procps", by the way. You can find this information by asking dpkg on an older Debian, e.g. Bookworm (here: a not yet upgraded PBS3):

~# dpkg -S /etc/sysctl.conf
procps: /etc/sysctl.conf

On my PVE9 (upgraded from 8.x) it has vanished:

~# lsb_release -c; dpkg -S /etc/sysctl.conf
Codename:       trixie
dpkg-query: no path found matching pattern /etc/sysctl.conf

The "procps" package does still exist, of course:

~# apt policy procps
procps:
  Installed: 2:4.0.4-9
  Candidate: 2:4.0.4-9
  Version table:
 *** 2:4.0.4-9 500
        500 http://ftp.de.debian.org/debian trixie/main amd64 Packages

So yes, checking one of my systems it seems that sysctl.conf is gone with the upgrade from Bookworm to Trixie...

This is a Debian Trixie change as shown here.

During the PVE 8 to 9 upgrade process, the pve8to9 --full script will have warned you of such, as I have documented here.

Good luck.
