installation_crash

[mn]

This was a re-installation of Ubuntu 18.04.1 on a system that was unstable with many restarts without pattern. The motherboard eventually died. It was replaced, moving all hardware to the new motherboard.
Then the reinstallation was being made from a LiveCD of the same Ubuntu flavour 18.04.1. I used the "something else" option for partitioning and went to chose my existing partitions on different hard disk drives and only reformatting the root partition for a clean install. My /home is in an independent partition already.
Then proceeded with confirmation of selections and then started partitioning and then the crash.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. The following messages can be found in UbiquitySyslog.txt which was automatically attached to this bug report:

Dec 18 19:02:57 ubuntu kernel: [ 4814.637156] SQUASHFS error: zlib decompression failed, data probably corrupt

You probably had a bad write to your media and no doubt the issue was resolved some time ago. Should you have such a problem in the future please try the option to check the integrity of the image from the installer boot menu, and if this confirms that the media is corrupt, try re-writing it.
