I'm using Windows 10 and Ubuntu side by side on my HP Pavillion laptop with :
Intel® Core™ i7-8750H CPU @ 2.20GHz × 12 NVIDIA Corporation GP107M [GeForce GTX 1050 Ti Mobile] / GeForce GTX 1050 Ti/PCIe/SSE2and 16 GB of Ram.
According to 'systemd-analyze' :
Startup finished in 4.110s (kernel) + 1min 8.206s (userspace) = 1min 12.316s graphical.target reached after 1min 7.940s in userspace
if i type in 'systemd-analyze blame' :
39.619s man-db.service 38.758s plymouth-quit-wait.service 26.468s snapd.service 18.378s logrotate.service 18.269s dev-sda4.device 17.726s networkd-dispatcher.service 12.867s NetworkManager-wait-online.service 11.566s udisks2.service 10.604s dev-loop21.device 10.500s dev-loop25.device 10.321s dev-loop22.device 10.190s dev-loop3.device 9.950s dev-loop26.device 9.862s dev-loop31.device 9.718s dev-loop23.device 9.217s dev-loop28.device 9.184s dev-loop16.device ... it gets worse day by day and with each update. Saw a few threads about this problem but they were ancient by OS standarts (Ubuntu 12 or 14).
What can i do to get it back to speed again?
Edit: Paladin wanted me to do two things and here are the results of those:
#1 the result of sudo systemctl status man-db.service is :
● man-db.service - Daily man-db regeneration Loaded: loaded (/lib/systemd/system/man-db.service; static) Active: inactive (dead) TriggeredBy: ● man-db.timer Docs: man:mandb(8)
#2 Also after sudo journalctl | grep -i error > error.txt i got a 93997 line text file. I am including the log of the last boot below.

Also purged the snap-store and snapd. created the "nosnap" file so that it may not be installed again.(I could just go with linux mint) the boot time is now 1 min and 2 seconds. Which is not perfect but i am running the OS from a mechanical disk.
The top time takers on boot are
32.070s plymouth-quit-wait.service 15.017s systemd-journal-flush.service 13.740s networkd-dispatcher.service 13.304s NetworkManager-wait-online.service 10.085s accounts-daemon.service 8.072s udisks2.service 7.821s dev-sda4.device 7.050s smartmontools.service 6.787s NetworkManager.service 6.106s grub-initrd-fallback.service 5.930s polkit.service 5.258s avahi-daemon.service 5.256s bluetooth.service 5.243s iio-sensor-proxy.service 4.565s power-profiles-daemon.service 4.361s ModemManager.service 4.324s switcheroo-control.service 4.320s thermald.service 4.318s systemd-logind.service 4.086s wpa_supplicant.service 3.948s cups.service My systemd-journal seems to be 1016,2M (checked with journalctl --disk-usage) I did a journalctl --verify Invalid entries. After that i did a sudo journalctl --vacuum-size=1G --vacuum-time=5d --vacuum-files=5 and the journal size is reduced to 224M
after a reboot i see that i can boot in 50.189s.
Startup finished in 3.967s (kernel) + 46.221s (userspace) = 50.189s graphical.target reached after 46.086s in userspace Now the top time-spenders on boot are:
