after installing Ubuntu 12.04.1 and 12.10 respectively for over a few times, i noticed that within the Software Sources, by default, the Unsupported Updates (precise backports / quantal backports) are ticked.
By removing that source BEFORE applying the system updates, i can clearly say that it stopped many issues, like a lack of wifi driver recognition (see here: WiFi problem after Ubuntu 12.10 update ) or other issues - from originally occurring.
Is there any plan to update this issue towards Raring? By this i call to simply tick the *-security and *-updates only.
cheers.
This is by design.
From the 12.04 Release Notes
PS: I very much doubt there is anything related to wireless (or any kind of drivers) in the backports.
PPS: Not sure what's going to happen in Raring.
