Hello and thanks for this bug report. The upgrade fails because of:

  chown: changing ownership of '/etc/sssd/sssd.conf': Operation not permitted

which is strange, given that apt runs as root. Did you perhaps `chattr +i` that file, or something like that?

Are you able to reproduce the problem from a freshly installed Ubuntu system? Also, I see:

  InstallationMedia: 22.04.4 2024.05.04 "Joby Jammy Jellyfish" (20240504)

If you are using an Ubuntu derivative, then this bug may belong to the derivative.
