Thank you for taking the time to report this bug and helping to make Ubuntu better.
Lubuntu has used sddm for all LXQt releases (ie. since Lubuntu 18.10), and the upgrade from an release that used lightdm/LXDE is unsupported due to breakage as was warned about in documentation, eg. https://lubuntu.me/focal-2-released/ "Note, due to the extensive changes required for the shift in desktop environments, the Lubuntu team does not support upgrading from 18.04 or below to any greater release. Doing so will result in a broken system. If you are on 18.04 or below and would like to upgrade, please do a fresh install." The error you are describing is a user-created issue by using unsupported upgrade procedures that were documented as creating issues later, and this is warned about breakage. The fresh install would have prevented this. As such I've marked this bug report as "opinion". If you believe I'm in error, please leave a comment explaining why and the bug report can then be returned to "New" (you may find it'll then be marked as "Won't Fix") ** Changed in: lightdm (Ubuntu) Status: New => Opinion -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1977683 Title: Lubuntu error has_option: command not found / no ssh-agent after updating to 22.04 Status in lightdm package in Ubuntu: Opinion Bug description: 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.
