I can't make new snapshots anymore, it always says:
E: The system partition has an unsupported subvolume layout. Only ubuntu-type layouts with @ and @home subvolumes are currently supported.
I checked the log files at /var/log/timeshift/ and compared a successful run with a failed run and found out that after Searching subvolume for system at path: / it no longer lists any of my subvolumes, which are @, @home and @swap (that last one I made)
This also happened on a different laptop where I had installed Arch Linux afresh and timeshift never worked the first time.
Does this happen to anyone else? Does anyone know how I can fix this? Is this something I need to report to the Linux Mint devs?

For timeshift to work with BTRFS your sub volumes need to adhere to strict requirements. Otherwise, it wont work: Arch Wiki: Timeshift. Make sure you are set up properly.

I already have another laptop that match the strict requirements of just @ and @home, but timeshift refuses to recognise that my btrfs partition has any subvolumes still.
Besides, it used to work as long as you had @ and @home. Then it wouldn't work if your swap was saved to any of those subvolumes. Then it would work as long as swap was saved to a different subvolume other than @ or @home. Since some update either at the tail end of 2024 or this year, that stopped working again, even a configuration that meets its strict requirements.

Since you have btrfs set up, have you considered moving over to snapper? It's really easy to set up, doesn't care about the configuration and gives you bootable snapshots. That's what I did on my system, because Timeshift for me has been a real PITA lately as well.

Fair enough, I'll give snapper a shot.

Follow the instructions here: https://www.lorenzobettini.it/2023/03/s … rch-linux/
Only took me like 15 Minutes and works like a charm.
