Download new version in KDE&#x27;s update tool. Same as doing apt-get dist-upgrade as far as I know. It was certainly offered to me.<p>In the end I reinstalled regular old Ubuntu, because there are no real alternatives, and it&#x27;s at least marginally less in need of grandma-hard maintenance. (I still had to go into Grub&#x27;s hidden boot menu and fiddle with the boot flags to get it to work - Ubuntu&#x27;s installer doesn&#x27;t do nomodeset by default, even though many brand new graphics cards will boot you into a black screen without it).
