Being new to Ubuntu I try to avoid any install without looking for problems others have experienced. The upgrade to 12.04 seems to have had quite a few users experience problems. Do these generally get resolved or are they sometimes bugs? Is there an approach that can be used to determine the impact on particular applications, or a list of known problem apps?
Update: Desktop, new with on board graphics. I guess I am just trying to get a handle on how smoothly upgrades are in general with Ubuntu. I am on 11 and shortly after got advised of the upgrade to 12 being available.
I do not think I have any special apps yet, but did install kubuntu too. Although switched back to Ubuntu most of the time. But seeing lots of the problems relate to basics like ethernet connections got a little nervous as I have no idea of the size of userbase and whether the experienced problems are a rarity or common issues. Do such issues feed back to devs and result in a maintenance release if a bug is uncovered for example.
