It seems that you are not aware that the "systemd-analyze blame" command starts a pager program.
If you do not know how to interact with a pager, then you probably better use
systemd-analyze --no-pager blame

Your output shows (among others) a whole bunch of loop mounts.
I do not think that they all are needed, and avoiding some of them will speed up the boot process.

What is the output of

df -h
snap list --all

Don't know nothing about the "pager program" I will find out what it is.
Do you need the results of systemd-analyze --no-pager blame?

That is one of the specifics of snap: there are up to two old versions of an application left, needing space and slowing down booting.

If you want, you can remove the superseded ("disabled") versions of the snaps on your system.

snap remove color-picker --revision=16
snap remove core --revision=11187
snap remove core18 --revision=2066
snap remove core20 --revision=975
snap remove firefox --revision=553
snap remove gnome-3-34-1804 --revision=66
snap remove gtk-common-themes --revision=1514
snap remove htop --revision=2185
snap remove qalculate --revision=360
snap remove qt551 --revision=31
snap remove snapd --revision=12159

That is unexpected. After removal of cruft the boot process takes longer than before.
I assume, that there was something else going on that slowed down booting.

What are now the top lines for the command
systemd-analyze --no-pager blame?

By the way, in my opinion 2 minutes for booting is acceptable, if you have slow disks (not SSD)

With stopwatch boot times:
It takes 3m 23s to show the main screen then it carrys on booting until 4m 32s that is when the
HDD led stops flashing.
I accept 2 minutes it is more or less the time of older Ubuntu versions.

luis@luis-desktop:~$ systemd-analyze --no-pager blame
34.712s snapd.service
32.050s plymouth-quit-wait.service
16.766s dev-sda5.device
16.022s systemd-journal-flush.service
13.616s networkd-dispatcher.service
10.102s NetworkManager-wait-online.service
 9.827s dev-loop11.device
 9.817s accounts-daemon.service
 8.957s dev-loop17.device

"that is when the HDD led stops flashing."

Is this a conventional platter-based disk or a SSD or NVMe device?

The most effective measure for speeding up the boot process probably is switching to a faster system (e.g. purchasing a SSD, eventually also adding additional memory).

It is a platter-based disk

There is not much that can be done on the current system except uninstalling software that you do not use.

I am surprise of this version taking so long I have other HDD one with Kubuntu 20.04 another
with Mint 20.1 and all take under 2 minutes to boot.
Thanks it was a good try.
