Not the poster you're replying to, but I've had a few issues occasionally. Biggest one was an Xorg update that was done incorrectly by the maintainers. The X server itself was updated, but GLX components weren't, which led to some incompatibility between the two. Net result being that the screen was blank after boot. I've also had issues where the Ubuntu's apt repos would somehow get themselves into a locked up state where it errored out and refused to work; I don't remember what was the exact error, something to do with the upstream repos and the local cache, I just remember it was very difficult to recover; I think it might've required a reinstall of Ubuntu and I do remember it happening more then once. Most of the other issues IIRC were annoyances more then anything else.
