[Bug 1857649] Re: installation displays error "cannot remove xxxx (file adress) read-only file", then installer crashes

[Chris Guiver]

Checking through the Syslog, IO errors are repetitive. Because of
numerous IO errors the file system flips to RO to protect any data on
it.

Dec 26 23:26:00 ubuntu kernel: [    8.716013] EXT4-fs warning (device sda1): ext4_clear_journal_err:5115: Filesystem error recorded from previous mount: IO failure
..
Dec 26 23:59:01 ubuntu kernel: [ 2003.111196] blk_update_request: I/O error, dev sda, sector 9393041 op 0x0:(READ) flags 0x3000 phys_seg 1 prio class 0

I would check your hardware's health (using your drives SMART
capabilities etc), then once corrected, try again.
