Ich habe mit einer sehr langsamen Bootzeit bei der Verwendung von Ubuntu zu kämpfen.
$ systemd-analyze time
Startup finished in 9.143s (kernel) + 2min 4.895s (userspace) = 2min 14.038s
graphical.target reached after 2min 4.885s in userspace
das ist furchtbar lang, ich verwende auch keine prähistorische Maschine, der Prozessor ist ein Intel i5-4200M, das ist ok, sollte keine 2 Minuten dauern.
Außerdem besteht dieses Problem seit der ersten Installation von Ubuntu auf dieser Maschine (vor etwa einem Jahr). Ich habe Ubuntu zuvor viele Male neu installiert, aber das Problem besteht immer noch.

von hier aus kann ich sehen, dass

39,768 Sek. snapd.service
33,076 Sek. dev-sda6.device
21,262 Sek. networkd-dispatcher.service
16,373 Sek. udisks2.service
sind höchstwahrscheinlich die Übeltäter. Gibt es jetzt eine Möglichkeit, sie zu deaktivieren? Soll ich sie vollständig deaktivieren? Ich habe ein /dev/sda6, daher glaube ich nicht, dass das deaktiviert werden sollte.
