I had the same error. I simply removed the lib32-db
package and then everything worked just fine.
The only thing I’ve really noticed so far is that the Kate widget is now gone, for those of you who’ve added it to a panel or had it visible in the system tray. The icon can be put back, but it is no longer a widget now — it is now merely a launcher for Kate.
Everything else still appears to look fine in Plasma 5.24.7 LTS.
There was however a problem when using pamac
to try and update the AUR packages, while yay
had no problem doing so. See the following thread.
Syncing database through Refresh database in pamac results in a pop-up that states, “Failed to synchronize AUR database”. In a terminal I ran yay -Syyu, and it synced fine and updated my AUR packages, but I still get the error message in pamac.
