Ich habe versucht, Etherpad zu installieren, aber es war nicht erfolgreich. Danach bootet mein Ubuntu 20.04 sehr langsam und es dauert zu lange, bis es bootet. Wenn ich die Systemanalysezeit sehe, $ systemd-analyze timewird Folgendes angezeigt:
Startup finished in 3.852s (kernel) + 1min 36.385s (userspace) = 1min 40.237s
graphical.target reached after 1min 36.375s in userspace```How can I fix this and make to boot fast as before. `systemd-analyze blame` results as 1min 34.672s plymouth-quit-wait.service
6.332s NetworkManager-wait-online.service
5.805s fwupd.service
