  1. Just what I was looking for–thanks! Makes the upgrade look pretty painless.

  2. Hi Ji m.
    Thanks for your article.
    Should this work with Kubuntu 18.04.1 LTS?
    Because I just tried that and my plasma stayed in 5.12.7. Can’t remember what version it had before I installed the PPA and updated through the command line.
    Hope you can help me.
    Cheers
