Removing snap and snapd

Code:


snap list # to list all the existing snap packages

sudo snap remove <name-of-the-package> # to remove the snap package

sudo snap remove snap-store # as example, to remove the snap-store package

Note: you can’t remove the ‘core’ snap package with sudo snap remove core, but we’ll do it later. Also kudos to Kevin Custer for the next step on snap core unmount!

Code:

sudo umount /snap/snapd/XXXX # to unmount the snap core service

Note: replace the XXXX with the ID number inside the core directory on your system. You can find it by running the df command and getting something like /dev/loop4 27776 27776 0 100% /snap/snapd/7264.

Code:

sudo apt purge snapd # to remove and purge the snapd package and all of its related services

Code:

sudo rm -rf ~/snap /snap /var/snap /var/lib/snapd # to remove all the folder related to snap, if existing

Now see what else is worth removing with this

Code:

sudo pip install glances

glances
