I'm unable to upgrade using the instructions here: https://help.ubuntu.com/community/PreciseUpgrades/Kubuntu
I've installed all updates, but I cannot see any new version available. I had to change muon-updater to see normal dist upgrades even though 12.04 should be a LTS. After changing this, I'm able upgrade to Ubuntu 12.04 LTS, not Kubuntu. I'm afraid to just press install... Running the following command (found on the earlier linked page) also want's to upgrade to Ubuntu rather than Kubuntu..
do-release-upgrade -m desktop -f kde -d
Any idea what might be wrong? Or should I just go for Ubuntu and hope for the best?
