Can shrink capacity of snapped core and kde-frameworks packages?

Question

I wrote this python script sometime back and it shows me the following:

ALL (ACTIVE & DISABLED) SNAP PACKAGES IN SYSTEM:

Active      52031488    /var/lib/snapd/snaps/snapd_17883.snap

I noticed that these active packages:

Active      58314752    /var/lib/snapd/snaps/core18_2654.snap
Active      66301952    /var/lib/snapd/snaps/core20_1738.snap
Active      76398592    /var/lib/snapd/snaps/core22_444.snap
Active     122359808    /var/lib/snapd/snaps/core_14399.snap

and

Active     444772352    /var/lib/snapd/snaps/kde-frameworks-5-91-qt-5-15-3-core20_1.snap
Active     457498624    /var/lib/snapd/snaps/kde-frameworks-5-96-qt-5-15-5-core20_7.snap
Active     273375232    /var/lib/snapd/snaps/kde-frameworks-5-core18_32.snap
Active     444768256    /var/lib/snapd/snaps/kde-frameworks-5-qt-5-15-3-core20_8.snap

are taking up a lot of system storage space. Their size keeps growing and growing. For Ubuntu 22.04 to work, does it really need all the /var/lib/snapd/snaps/core and /var/lib/snapd/snaps/kde-frameworks packages? Can some of these be deleted?

I am ignorant of why there are so many snapped core files and snapped kde-frameworks files. Are they repeats?

Like deb-packages, snaps have dependencies (other snaps). You can try the commands in this answer to see the dependencies of your snaps. — mook765, Dec 16 '22 at 11:36
@mook765 I have added what I found using your comment and answer. It seems that core18 and core20 is in use. However, core22_444 and core_14399 do not seem to be in use and yet it appears as Active.Why is this so? Can core22_444 and core_14399 be removed then? — Sun Bear, Jan 07 '23 at 14:55
Looks like you don't need them. You might have a snap installed and then later removed which needed them, so now they are left over. You'll have to run sudo systemctl stop snap-core-14399.mount and sudo systemctl stop snap-core22-444.mount and then snap remove --purge core and snap remove --purge core22 if you want to remove them. — mook765, Jan 07 '23 at 15:49

Can shrink capacity of snapped core and kde-frameworks packages?
