Users will sometimes run into errors performing updates on their system. Apport will usually detect these failures and file a bug in Launchpad. Unfortunately these bugs sometimes get assigned to the "linux" kernel package in Launchpad when really the issue is a result of a non-kernel related problem. It's best to examine the DpkgTerminalLog file that is usually attached to these bug reports as it contains descriptive error message output. Documented below are a few commonly reported issues, the DpkgTerminalLog messages that point to the real issue, and the bug number it should be marked a duplicate of.

Bug:105113 - No space left on device
