I'm here to ask the following:
Everytime I update (no matter on what computer), i get errors such as broken desktop, kernel panics, i have no sound (although i can solve it by forcing the reload of alsa-base), Ubuntu didn't power off after fresh installation (again i could solve it by altering the speech-dispatcher configuration)... The installations were broken after: Updating from unknown (and strange) version of ubuntu to 12.04, then to 12.10 LTS, and finally to 13.04 and everyting stopped from working normally on a netbook. And i got a kernel panic after upgrading to the latest kernel, i could only enter ubuntu by logging into an older kernel, Then i reinstalled ubuntu and got no sound, and ubuntu couldn't power off on a notebook.
The only way i know my computer keeps being stable, is to reject the updates from the update manager telling it to remember me later. Is there a way to update Ubuntu without getting these errors?
Far from that, Ubuntu and its community are great.
Sorry for my english if its bad and hard to read...
