Lubuntu very slow boot with an SSD for an unknown reason, systemd-analyze not helping

I have a laptop with a 250GB SSD and dual boot Windows 10 and Lubuntu.



Windows takes less than a minute to boot, but Lubuntu takes more than three.



I tried finding the reason why, though systemd-analyze blame says that the service taking more time to load takes only 6 seconds.



systemd-analyze blame

5.920s NetworkManager-wait-online.service
911ms dev-sda5.device
409ms snap-repair.service
266ms systemd-resolved.service
228ms networking.service

110ms plymouth-quit-wait.service
108ms NetworkManager.service
92ms ModemManager.service
79ms grub-common.service
77ms preload.service
...


Although it takes more than 3 minutes to boot:



systemd-analyze time

Startup finished in 8.659s (kernel) + 3min 636ms (userspace) = 3min 9.295s


This is the systemd-analyze plot graph, it shows a huge gap, but it doesn't show any process taking a lot of time.



How can I find out what's causing the system to take so long to boot and how can I improve it?



(this is systemd-analyze critical-chain)

          Disabling swap fixed the problem.



          Comment out the swap line in /etc/fstab and /etc/crypttab and reboot.
