I just tried installing the same snap, and the infrastructure and snap are fine, so it is likely a local issue.
Have you tried again? It's possible this was a transient issue.
Also, try snap download gimp and see if it downloads a .snap file and a .assert file.
Yes it still happens the only way to install gimp was to install another version using
sudo snap install gimp --channel=preview/edge gimp 2.99.10 397 preview/edge snapcrafters✪ -
rt@sys76:~$ snap info gimp

to install oldest from last line type below:
sudo snap install gimp --channel=preview/edge
I purged gimp twice to make sure is wasn't there:
rt@sys76:/tmp/0$ sudo snap remove --purge gimp
snap "gimp" is not installed
rt@sys76:/tmp/0$ sudo snap install gimp
error: cannot perform the following tasks:
- Fetch and check assertions for snap "gimp" (412) (cannot verify snap "gimp", no matching signatures found)
It's like the "signature keys" aren't matching with the application.
Is there a way to reset the settings to see if that's causing it? What do I do with the .snap file and the .assert file?
if snap download gimp worked then you can snap ack (followed by the assert filename) then snap install ./gimp*.snap
