I've just installed Ubuntu on a new build PC and I'm consistently experiencing long boot times of well over 2 minutes. I saw a lot of advice to use systemd-analyze, but wasn't sure how to interpret it for my situation. I've included the output of systemd-analyze and systemd-analyze critical-chain, below. Any help greatly appreciated.
$ systemd-analyze
Startup finished in 7.372s (firmware) + 5.319s (loader) + 3.706s (kernel) + 2min 22.911s (userspace) = 2min 39.309s
$ systemd-analyze critical-chain
The time when unit became active or started is printed after the "@" character.
The time the unit took to start is printed after the "+" character.
