My fresh Ubuntu install says I need some updates. Okay, but there are some problems.
First, it tells me to close the snap-store to update it, but the snap-store is not open.

@peterdrake Hmm, all I can think of is to use the good old command line:
sudo apt update && sudo apt upgrade && sudo snap refresh
@JensHannemann Update: after restarting the snap store, it's happy! Thanks!
