Impossible to install Ubuntu (no clear error messages - crashes at partitioning)
by obobskivich from LinuxQuestions.org on (#5MZCY)
Sorry for the vague title - but there's no clear error messages coming back from Ubiquity, and I'm stumped, hopefully a human can better parse this than my attempts at searching the web:
- Trying to install Ubuntu 20.04.2 LTS on a machine that was previously running Xubuntu with no issues.
- Installer consistently fails and crashes (hardlock system or 'unexpected error now exiting' with no error code, log entries, etc) after setting partition options (with/without encryption makes no difference but selecting encryption creates 'unexpected error with encryption').
I've tried swapping disks, tried setting SATA to IDE and AHCI in the UEFI, tried swapping RAM, created clean install image from fresh download, erasing disks (via wipefs and cfdisk), disabling/enabling IOMMU in BIOS, manually creating partitions, etc consistently it still always fails with no real explanation (but at least its always at the same point).
It will live boot with no problems, will run programs, mount the disks, do whatever, it just consistently fails with no explanation when attempting to actually install. I've never encountered this in 3+ years of working with Ubuntu, and it's got me stumped. Searching online for this non-error message of course returns nothing (or inchoate results). :banghead:
In the installer itself I'm always un-checking 'install updates' and 'install third party' and going for 'minimal install' as well, FWIW (and I've never seen this be an issue before, either with this machine or others).
Any help would be appreciated - like I said I can boot into a live environment just fine, so I can 'do things' with the system, I'm just not sure what else to try or do to move this along.
