Ubuntu software error "Error opening directory "/usr/share/appdata": No such file or directory"

Solution 1:

Ran into the same issue today, ending the process and re-opening it resolved it for me.

Steps to reproduce what I did:

  • Open System Monitor and search for snap-store
  • Select the snap-store process and hit End Process
  • Re-open Ubuntu Software

On the technical side of things this looks like a minor permissions issue, not much to worry about.

Solution 2:

I couldn't kill the snap-store process so I just restarted my computer to clear the error.
