Ubuntu crashed regularly after the 1st installation and is impossible to reinstall

[Charles]

I have installed Ubuntu on a virgin SSD with an AMD Athlon, the OS bugged regularly, it was frozen then impossible to shut down. I also had lines of error messages

I have made a second attempt for installation wich failed (see this related bug report. It seems to come from the disk.

I have made those installations from a USB stick

The log suggests that the disk is having error, more likely an hardware/disk corruption problem than an ubiquity one...

Could you check your disk/filesystem and see if problems are reported?

Thank you for taking the time to report this bug and helping to make Ubuntu better.
