Ubuntu recently introduced
snaps. Snaps are a new way of packaging applications in a way that there will be no dependency conflicts (because all dependencies are included). The only problem is that Ubuntu will create a
snap folder in your home folder that you will most likely never need to access.
If you, like me, find this folder annoying, you can hide it from Nautilus:
1 2 cd ~ echo snap >> ~/.hidden
This makes the folder invisible in Nautilus, but it will still be visible in other places (The terminal, for example).
