Apparently missing some files from the repository? Can't proceed any further so Polarr can't be installed.

Turns out an update to the system was required. I had forgotten that Linux requires a manual check for such things. There were quite a number of updates and, after a restart, the snapd installation proceeded as expected. So no bug.

Just needed a system update. Delete the bug report if you wish.
