Although I wasn't installing anything at the time, the crash reporter also popped up saying that a problem occurred while installing libopencore-amrwb0 0.1.3-2.1

Maybe that is related to apt crashing?


Changed in apt (Ubuntu):
importance: Undecided → Medium

Have you run memory checks? If everything crashes, it might be a faulty memory module.

I have downloaded Memtest86-7.5.iso but haven't yet got the 40_custom entry correct to launch it via loopback. I guess I could burn it to USB/CD.
