Unable to shutdown or restart from log-in screen

[Paul White]

[Impact]

 * Shutdown and restart options don't work from the login screen, when the user is not logged in.

[Test Case]

 * Start the system and don't log in, or log out in case the system is set up with autologin.
 * Restart, then shut down the system using the option in the upper right corner of the login screen.
 * Observe both operations working.

[Regression Potential]

 * The fix is treating treating the greeter as user display sessions by cherry-picking upstream's change released in v243. The fix itself is very small, but there may be non-obvious security implications.

[Original Bug Text]

When selecting the shutdown icon from the log-in screen you are prompted with a dialog that allows you to either cancel, restart or shutdown.

It has been noted that the restart and shutdown options no longer work.

[Iain Lane (laney)]

I haven't tested this, but since seb128 pasted the relevant messages in IRC.

I bet you that it's because polkit isn't considering the D-Bus session of the greeter to be 'active', because it's not finding it.

If someone would like to test build a systemd with this commit included:

https://github.com/systemd/systemd/commit/a2dcb1d78737d3daa301ee63fbdd02837acb71a8

I suspect the problem would be fixed.

[Iain Lane (laney)]

s/D-Bus session/logind session/

[Iain Lane (laney)]

yeah ok just checked, that totally fixes it, have asked the systemd maintainer if that patch can be included in the next update

[Sebastien Bacher (seb128)]

I've tested it as well (saw you asking yesterday and kicked a build but I didn't see you tested as well meanwhile), I can confirm it fixes the issue

[Balint Reczey (rbalint)]

I've pushed the fix to schedule it for the next upload:
https://code.launchpad.net/~ubuntu-core-dev/ubuntu/+source/systemd/+git/systemd/+ref/ubuntu-eoan

I'm waiting a few days to see if there are other fixes showing up to include in the same upload.

[Balint Reczey (rbalint)]

Fixed in Focal, to be SRU-d to Eoan.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Scott Dennis (sdennis91)]

i got an email about released. I also notice on here that a fix has been released. I don't see it as an update via software updates. How to I get the fix.

[Paul White (paulw2u)]

Comment #10 means fixed in focal (20.04) only for now.
Stable Release Update in eoan (19.10) to follow in due course.

[Łukasz Zemczak (sil2100)]

Hello Paul, or anyone else affected,

Accepted systemd into eoan-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/242-7ubuntu3.2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-eoan to verification-done-eoan. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-eoan. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

[Efthimios Chaskaris (echaskaris)]

The feature works now. You might want to release it earlier than 7 days.

[Paul White (paulw2u)]

Looks like I was a little slow in testing and changing the tags but for the record:

Rebooted into Ubuntu 19.10 to confirm Restart and Poweroff options were not working
Logged in, enabled -proposed, updated systemd to version 242-7ubuntu3.2
Logged out and confirmed 'Poweroff' now works
Started PC and without logging in confirmed 'Restart' now works

Thanks for the fix.

[Ubuntu SRU Bot (ubuntu-sru-bot)]

All autopkgtests for the newly accepted systemd (242-7ubuntu3.2) for eoan have finished running.
The following regressions have been reported in tests triggered by the package:

gvfs/1.42.1-1ubuntu1 (amd64)
systemd/242-7ubuntu3.2 (ppc64el)
ndctl/unknown (armhf)

Thank you!

[Scott Dennis (sdennis91)]

Thanks for the fix. I tested it on my end and I confirmed this bug as being fixed. I can now restart and shutdown via gdm.

[Miroslav Zaťko (mirec-z)]

still there with ubuntu 19.10 everything & freshly upgraded

[Md Ayquassar (mdayquassar)]

Same for me as of this today: logging off, then navigating through the menu in the right upper screen corner till the turn-off button and then clicking it produces no effect in eoan.

[Paul White (paulw2u)]

The fix has not yet been released but is in a period of testing. Did you follow the instructions in comment #15? The updated package is in -proposed and will be for a *minimum* of seven days from the date of comment #15.

If you want to test whether the update works for you then please follow the instructions in comment #15. If that update doesn't work for you then please confirm that you have enabled -proposed and downloaded the updated package.

[Md Ayquassar (mdayquassar)]

@paulw2u My apologies. After double-checking, I found out that (for whatever reason) eoan-proposed were disabled for me. I'll retest and report here if an update doesn't help.

[Md Ayquassar (mdayquassar)]

After a few tests, I confirm that the bug looked fixed to me.
