Pantheon: unable to logout from session

davidak commented 5 years ago

Issue description

I reproducibly get this log message when trying to log out from wingpanel.

Apr 30 17:00:14 ethmoid io.elementary.cerbere.desktop[6410]: GDBus.Error:org.freedesktop.login1.NoUserForPID: Caller does not belong to any logged in user or lingering user

When i try to lock the screen:

Apr 30 17:05:52 ethmoid io.elementary.cerbere.desktop[6410]: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ScreenSaver was not provided by any .service files

When i try to suspend:

Apr 30 17:06:18 ethmoid io.elementary.cerbere.desktop[6410]: GDBus.Error:org.freedesktop.DBus.Error.InteractiveAuthorizationRequired: Interactive authentication required.

When i try to shut down:

Apr 30 17:06:52 ethmoid io.elementary.cerbere.desktop[6410]: GDBus.Error:org.freedesktop.DBus.Error.InteractiveAuthorizationRequired: Interactive authentication required.

When i try to restart:

Apr 30 17:07:26 ethmoid io.elementary.cerbere.desktop[6410]: GDBus.Error:org.freedesktop.DBus.Error.InteractiveAuthorizationRequired: Interactive authentication required.

Workaround

Create another user and switch to that user. The login screen appears and the system is practically locked. Just login with your user the next time you need the system.

Steps to reproduce

open journalctl -f
try to logout
see only the log message

I lost that strange session by:

switch user
try to log back in to the current user
session crash https://github.com/NixOS/nixpkgs/issues/60082

In a new session, i'm unable to reproduce the behavior.

By seeing org.freedesktop.ScreenSaver was not provided by any .service files I'm almost certain that lightlocker isn't running or crashed somehow.

And I can just quickly reproduce the locking issue by killing its daemon and trying to lock the session.

 GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ScreenSaver was not provided by any .service files

For the issues with suspend, shutdown, and restart

GDBus.Error:org.freedesktop.DBus.Error.InteractiveAuthorizationRequired: Interactive authentication required.

means

Access to the requested operation is not permitted. However, it might be available after interactive authentication. This is usually returned by method calls supporting a framework for additional interactive authorization, when interactive authorization was not enabled with the sd_bus_message_set_allow_interactive_authorization(3) for the method call message.

usually it's because you need to be root. Maybe something was inhibiting it?

Maybe something was inhibiting it?

I have closed every desktop program, but maybe something is broken in the background.

Anything i can do to debug when i encounter it next time?

How can i check if it's running? Is it a service?

All systemd services are running except some "session-*.scope".

[root@ethmoid:~]# systemctl --failed

"session-9.scope" is active running. "Session 9 of user davidak"

I added a workaround i use now to the issue description.

same problem here on shutdown Unable to shutdown: GDBus.Error:org.freedesktop.DBus.Error.InteractiveAuthorizationRequired: Interactive authentication required.

if found an issue to this topic: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1847896

is there a workaround?
