I have followed this tutorial from snapcraft.io

I did the following commands:

sudo apt update
sudo apt install snapd

everything works.

but then I did this:

sudo snap install p7zip-desktop

and I receive an error:

error: snap "p7zip-desktop" has "install-snap" change in progress

This error means that snap is doing something in the background. You can see what is going on by typing the following in the terminal:

snap changes

If after some time the situation doesn't resolve itself you can abort any of the processes that are listed by typing:

sudo snap abort id

NOTE: "id" should be replaced by the number at the beginning of the row of the process you want to abort (e.g. sudo snap abort 123)
