SUMMARY
Whenever I install ubuntu, first thing I do is uninstall all snaps and snapd and then pin-priority -1 to snapd to prevent it from installing.  Discover Software Center always works on Lubuntu after doing this on 23.04, 23.10, etc.

With 24.04, after snapd is removed and all snaps are purged, Discover Software Center WILL NOT LAUNCH.
We try to identify why by running it through Terminal, terminal gives two errors. I can't remember what the first error was but it was something generic.

The second error dialogue in terminal I got was generated when I was running sudo plasma-discover, it said this:
kns-backend attempted (failed) and listed other backends in parathensis (snap, flatpack, etc).

I tried uninstalling and removing all files and re-installing with apt.  Didn't work.

What fixed it:  If you REMOVE snapd, you have to remove plasma-discover-snap-backend package.  The plasma-discover snap package that comes with installing Discover has to be removed.  Once I deleted the snap package related to Discover store (that auto installs with it), Discover Software Center launched.  This never happened before on older installations of Ubuntu.  Please fix this because the fix is not intuitive.  It complains that kns-backend and others are failing (when all the backends are installed), and the only backend that doesn't work is the snap one and needs to just be uninstalled.

Latest version of Lubuntu 24.04

ADDITIONAL INFORMATION
Please fix this so people won't wonder how to make Discover Software Center work after purging snapd. F*ck snaps.
