Backups not working after Ubuntu 26.04 upgrade

[sponch]

Hi,
after upgrading to Ubuntu 26.04 one of my instances can't backup anymore (EXT4, SSHFS). Creating a new backup storage ends in the same problem, Backups break up immediately:

@sponch this is because of sudo-rs , you have to remove it. See https://docs.cloudron.io/guides/upgrade-ubuntu-26/#post-upgrade
