Comment # 3 on bug 1226109 from Richard Brown

Hi, thanks for the bug report, but its lacking some important details that as a
reporter you should have included:

During your first installation (at 12:19 on 08-06-2024)

- You were prompted that an existing backup existed (when it did not)
- You chose 'No' to delete the backup that didn't exist
- You got an error message "Command /usr/bin/rmdir /var/lib/tik/mig/mnt FAILED"
and that's how your install ended

During your second installation (at 12:29 on 08-06-2024)

- You were again prompted that an existing backup existed (when it did not)
- You chose 'Yes' to use the backup that didn't exist
- You got the error message you used to report this bug with

Now I'm not writing all this to scald you, but just to help you write good bug
reports in the future..I nearly wasted a lot of time debugging the second
installation when infact ALL your issues were related to the first

During your first installation, the installer was probing your existing
installation on your target disk

For some reason, after probing, your system refused to unmount the disk
cleanly. This left a mount point lingering in /var/lib/tik

tik's migration module assumes if there is ANY files in /var/lib/tik then
that's a backup which can be used.. but there was no backup..just the broken
mount point from your misbehaving existing filesystem

Every other problem came after that point - your first installation failed
because of the misbehaving filesystem , and your second installation failed
because your tried to use a backup that wasn't actually there so it was trying
to restore files that didn't exist

So, we need to address the core bug(s)

tik should use somewhere else for it's mounting than the same location we check
for backups

and we need to figure out a way of more gracefully handing misbehaving existing
filesystems

We'll get on it..meanwhile, a quick and dirty work around would be to backup
anything you want from your existing installation, format the disk you want to
install, and then Aeon will install fine.
