I have a working workaround
if you can : upgrade your ubuntu to 22.04.2 in place if possible
or reinstall a server with ubuntu 20.04 with zammad then install latest zammad package
the command is :

do-release-upgrade

this will take about 40min
then modify your repo file : /etc/apt/sources.list.d/zammad.list
change 20.04 to 22.04

then do a apt update and a apt upgrade, this will update zammad to the right ubuntu

you can do a backup and restore to the newest ubuntu or stay in the new ubuntu if you’ve from scratch.
and voilà!
hope there will be a fix for this issue

Just for your information… the steps you’ve taken are not needed. The documentation actually guides you through exactly this use case:
https://docs.zammad.org/en/latest/appendix/backup-and-restore/migrate-hosts.html

The issues you have clearly indicate that you backed up as FULL_FS_DUMP=yes (default) which overwrites OS and version dependend files on the host you restore to.

For the next time, the config settings and their description can be found here:
