[Bug 1905474] Re: error at installation

[Chris Guiver]

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

I see squashfs errors -

Nov 24 21:43:54 ubuntu kernel: [  538.269782] SQUASHFS error: zlib decompression failed, data probably corrupt
Nov 24 21:43:54 ubuntu kernel: [  538.269788] SQUASHFS error: squashfs_read_data failed to read block 0x1e9c75cc

Your system is reported to have passed it's md5scan
"CasperMD5CheckResult: pass", however if the device/hardware/VM you are
using has insufficient ram for the setup, squashfs errors have occurred
before. Providing more RAM *may* fix the issue.

Squashfs errors are usually faulty installation media (bad ISO or given
the pass, flaky/bad write to media, or failing installation media
holding the expanded ISO). I would re-check that.
