[Bug 2092438] Re: System fails to restart after install

[Olivier Gayot]

I compared the behavior with oracular, where the inhibit exists as well:

on oracular
-----------
* ubuntu at ubuntu:~$ reboot        -> fails (inhibited)
* ubuntu at ubuntu:~$ sudo reboot   -> succeeds


on plucky
---------
* ubuntu at ubuntu:~$ reboot        -> fails (inhibited)
* ubuntu at ubuntu:~$ sudo reboot   -> fails (inhibited)



Indeed, the behavior has changed in systemd 257. quote from the release notes [1]:

        * systemd-logind now always obeys block inhibitor locks, where previously
          it ignored locks taken by the caller or when the caller was root. A
          privileged caller can always close the other sessions, remove the
          inhibitor locks, or use --force or --check-inhibitors=no to ignore the
          inhibitors. This change thus doesn't affect security, since everything
          that was possible before at a given privilege level is still possible,
          but it should make the inhibitor logic easier to use and understand,
          and also help avoiding accidental reboots and shutdowns. New 'block-weak'
          inhibitor modes were added, if taken they will make the inhibitor lock
          work as in the previous versions. Inhibitor locks can also be taken by
          remote users (subject to polkit policy).

Title:
  System fails to restart after install

Status in subiquity:
  New
Status in subiquity package in Ubuntu:
  In Progress

Bug description:
  Testing Ubuntu Plucky Desktop daily ISO dated 24-12-24

  Upon completion of the installation the system fails to restart -
  instead it re-enters the desktop.

  If the system is then restarted by selecting "restart" (in the upper
  right-hand corner)then all works as normal - a message appears to
  remove the media and the system reboots.
