Sometimes it may be desired to get packages from apt instead of snap,
e.g. the Chromium snap doesn't have hardware acceleration for video conferences.
# Remove all snap packages
snap list
sudo snap remove --purge $SNAP_NAME
# Remove cache
sudo rm -rf /var/cache/snapd/
sudo apt autoremove --purge snapd gnome-software-plugin-snap
rm -rf ~/snap
# Block snap from auto-installing
sudo apt-mark hold snapd
sudo apt install gnome-software
