Dear Maintainer, When starting up, I get the following message in /var/log/lightdm/lightdm.log: [+0.26s] DEBUG: Could not run plymouth --ping: Failed to execute child process "plymouth" (No such file or directory) As far as I can tell, there is no package that lightdm depends on, recommends or even suggests that provides this program.
Yes, that's harmless. Regards,
