Some variant of this has been asked before - emacs daemon crashing when it has been built with Gtk3 etc - but I couldn't find any solution to this.
I've built Emacs 27.1 from source on Xubuntu 20.04 with --with-x-toolkit=lucid. I then copied emacs.service into $HOME/.config/system/user/ and ran systemctl --user start emacs.service.
It ran for a while and crashed with the following message:
Job for emacs.service failed because a timeout was exceeded.
See "systemctl --user status emacs.service" and "journalctl --user -xe" for details.
Note: I don't need to open a file or resize emacs etc. The daemon fails even when I don't start an emacsclient.
The outputs of both the recommended commands are given below:
journalctl:
anaravi@anaravi-xxxxx:~$ journalctl --user -xe
