Comment 9 for bug 1606238

On the desktop machine (from where I reported this bug for the first time)
I just removed every file inside ~/.local/share/gnome-software/ folder.
A moment later (didn't touch the machine), I installed the updates. "sudo apt update && sudo apt full-upgrade -y"
Then I had to go, so I shutted down the computer.
When I turned it on again, I could open ubuntu|gnome software from the dash and installed mypaint without any problem...
The laptop is not mine, so I'll try with it next week.
