Description Steve Zakulec 2022-10-31 16:08:46 UTC

SUMMARY
After upgrading to Neon 22.04, Skanlite was removed, and can't be reinstalled due to missing dependencies.

STEPS TO REPRODUCE
1. Search for Skanlite in Discover
2. Click install
3. Notice error messages going by

OBSERVED RESULT
Skanlite isn't installed due to missing dependencies

EXPECTED RESULT***
Skanlite installs without issue, pulling in any missing dependencies automatically.

Comment 1 Steve Zakulec 2022-11-04 02:08:13 UTC

Think I figured out what was going on- libpoppler-glib8 was getting blocked by a small number of packages I had on my system from 20.04 (possibly Wine-related packages).
Once I tried installing libpoppler-glib8 from a command prompt with "sudo pkcon install libpoppler-glib8", I was asked if it was okay if some packages were deleted in order for libpoppler-glib8 to install itself.
Once I said yes, the package installed, and then skanlite had no problems installing.
