Even though there have been a few updates, I am still having problems getting Discover to work in Plasma 6.3 on Neon as it hangs at the end of the search. I have discovered a workaround for the problem.
- Open discover and wait until it hangs at the end of the search.
- Close discover.
- Turn off networking
- Open discover. You should get an error message about the network.
- Navigate to the update tab. You should now see the file list and working update button.
- Leave discover open on the update page and turn networking back on.
- Go back to discover and click update.
This works for me. Discover is still broken after the updates, but at least it seems to work better than doing all via command line, which has failed in a couple of ways on my rig.
