Boot takes a long time due to "plymouth-quit-wait"

[Michal Hečko]

Fresh install of Ubuntu 24.04. Boot takes too long. Everything seems corrent, plymount's loading screen disapears after a while (few seconds) and black screen happends. This is the time when GDM3 should shows up. I have to wait few minutes and then after changing TTY by pressing i.e. CTRL+ALT+F2 and then immediately switch back by CTRL+ALT+F1 GDM3 shows up.

I figured out, that "plymouth-quit-wait.service" took too much (4+ minutes).

Is there any evidence of plymouth crashing in /var/crash?

[Michal Hečko (michalhecko)]

No evidence unfortunately.

Next time the problem happens and you can finally log in, please run:

  journalctl -b0 > journal.txt

and attach the resulting text file here.

Another boot another lag (just a little less than last time):

2min 32.337s plymouth-quit-wait.service

But in journal there are a lot of interesting delays. But nothing in /var/crash again.
