Wow. I installed Kubuntu on my laptop just to play with it just now.
I hate it. I get errors when packages install successfully. They make some thing (/etc/fstab, for one) completely stupid. For some idiotic reason, they decided that using UUIDs to reference the partitions in a PC partition table would be a good idea despite the fact that it doesn't make any fucking sense (easy to change back, but still dumb), it flagged a distribution upgrade despite me having the latest version, then bombed when it realized that my distribution was, in fact, up-to-date.
Screw this.
