Bug ID: 456790
Summary: "Cannot create unix session" - polkit-kde fails to
start
Product: policykit-kde-agent-1
Version: 5.25.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: jacek.jag...@outlook.com
CC: d...@kde.org, jgrul...@redhat.com, jrez...@redhat.com
Target Milestone: ---
SUMMARY
On my fresh install of Solus 4.3 `polkit-kde` stopped working at all, no matter
what I do. It did stop working around the time I updated to latest Plasma, but
I updated my laptop with a year old installation and nothing broke.
How can I gather more logs? I really want to fix it!
STEPS TO REPRODUCE
1. Last thing I did is I went to Startup -> SDDM settings and I changed
automatic login from X11 to Wayland. It was after I updated Plasma but not
rebooted yet. (probably it is not what caused it)
2. Reboot, it still booted into X11, not Wayland
3. See the error in journalctl, try to run `polkit-kde-authentication-agent-1`
manually with the same results.
OBSERVED RESULT
The box to input root password doesn't appear at any point, when using software
centre or trying to change options in Plasma Settings that should require root
privilidges. This is the output of `sudo journalctl -b | grep polkit`:
