I recently found /snap/gnome-3-26-1604/
on my Ubuntu 18.04.1 machine. I found this other related question, but not much else to explain what it is used for. I also seem to have several versions of it: /snap/gnome-3-26-1604/70
, /snap/gnome-3-26-1604/74
and /snap/gnome-3-26-1604/current
.
What does this snap do? And can it be removed without breaking anything significant?
It should be this snap: https://snapcraft.io/gnome-3-26-1604
So, unless you have another gnome stack in usage, you should not remove it.
Edit: As snap always downloads a whole new version instead of updating and does not auto-delete the old ones, yes, you can delete the old ones. Check which are disabled with
snap list --all
and remove withsnap remove --revision XXX gnome-3-26-1604
where XXX is the revision number (eg 70).
