The GUI does not detect btrfs-inside-LVM layout

[tripleo1]

Describe the bug
I have installed Arch manually

• I have then created a subvolumes @ and moved the files accordingly
• Now when I run timeshift, it does not detect my BTRFS filesystem, even though it is there and I have the Ubuntu layout (see

attached screenshots with the layout and error).

I do not have a /mnt/timeshift/backup.

I do not see any disks in the GUI at all to select from.

Expected behavior
I would like to be able to use timeshift on this system.

This seems to be the same behavior as #585.

At least, the error message would have to be remove to not generate doubt.

Best regards.

For some reason I am not getting this error anymore. I am getting the one where it says Live USB (or such) mode.
