Tips and Tricks
1

If your clipboard history is gone after upgrade to Plasma 6.3, you can try this solution.

  1. Check ~/.local/share/klipper/ . If history3.sqlite is in the folder, you probably just hit 483136 – plasmashell doesn't wait for kconf_update , so you can try to restart plasmashell to see if the history is back.
  2. If Step 1 doesn’t work, follow the steps below:
    • Quit plasmashell (run kquitapp6 plasmashell)
    • Delete ~/.local/share/klipper/history3.sqlite
    • Manually run /usr/lib64/kconf_update_bin/plasma6.3-update-clipboard-database-2-to-3
    • and start plasmashell after the process is done.
