Public bug reported:
Hi,
I have updated several machines from Lubuntu 20.04 to Lubuntu 22.04 with
do-release-update -d
On all but one machine this worked well, but one machine, that formerly worked
without problems, now has no ssh-agent running after login, and the
~/.xsession-errors shows several xsession files to fail for the same reason:
/etc/X11/Xsession.d/30x11-common_xresources: Zeile 16: has_option: Befehl nicht
gefunden
/etc/X11/Xsession.d/75dbus_dbus-launch: Zeile 9: has_option: Befehl nicht
gefunden
/etc/X11/Xsession.d/90x11-common_ssh-agent: Zeile 9: has_option: Befehl nicht
gefunden
(german for: has_option: command not found)
Formerly mentioned in bug #1922414 (marked as solved) and its duplicate
#1940779 , but it isn't solved.
That's why there is no ssh-agent.
I have done some debugging to find, why it works on all but one of my
machines, and what's the reason.
Reason:
has_option is not a command, but a shell function defined in
/etc/X11/Xsession
On the good machines, the display manager is sddm, which seems to do the
job well.
The machine, that fails, is somewhat older and had formerly 18.04 running and
been updated to 20.04 then. It runs the display manager lightdm.
That's the problem:
lightdm runs /usr/bin/lxqt-session
and /usr/bin/lxqt-session directly opens and executes the scripts in
/etc/X11/Xsession.d without running /etc/X11/Xsession.
Therefore, the shell function has_option is never defined, but used
in the scripts, which do fail then.
Therefore, either lxqt-session needs to be made compatible with
/etc/X11/Xsession, or the upgrade-procedure 20.04 to 22.04 must replace
lightdm by sddm.
