[Bug 1914731] Re: [Errno 30] Read-only file system 'usr/bin' -> 'target/bin'

[Chris Guiver]

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

This installation looks like it was caused by a corrupted file system,
or device problems (sda6). I notice in the logs

Feb  5 02:46:35 ubuntu ubiquity:   Error reading device /dev/sda6 at 0 length 4096.
Feb  5 02:46:35 ubuntu kernel: [27830.148187] EXT4-fs error (device sda10): ext4_journal_check_start:83: Detected aborted journal
Feb  5 02:46:35 ubuntu kernel: [27830.148191] EXT4-fs (sda10): Remounting filesystem read-only
Feb  5 02:46:35 ubuntu ubiquity: mkdir: cannot create directory ‘/target/media’
Feb  5 02:46:35 ubuntu ubiquity: : Read-only file system

I've marked this bug as incomplete (due hardware issues), if you believe
I'm in error please leave a comment as to why, and you can return the
status to "New".

I suggest you validate the health of your hardware (esp. disk by
checking it's SMART status using `smartctl`, `gnome-disks` or whichever
tool you prefer), and possibly the integrity of your partition table
(https://help.ubuntu.com/community/Smartmontools). If you're unfamiliar
with these, I suggest seeking support, options available can be seen at
