Error Snapshots cannot be created in Live CD mode

[ciosbel]

Describe the bug
When I use the GUI or run the CLI commands, I always receive the following error:
E: Snapshots cannot be created in Live CD mode
Of course my system is not a live one. It's a properly installed ubuntu 20.04 on an odroid arm64 machine.
The distro is a one officially supported https://wiki.odroid.com/odroid-c2/os_images/ubuntu/v4.1 installed a couple of days ago, hence quite fresh.
The GUI allows me to properly create the /etc/timeshift.json but the create button is always disabled.
The external drive is an ext4 drive (raid1) with sufficient disk space (configured with rsync).
I've manually created the /timeshift directory.
I've followed the README to properly install/setup.
Thank you in advance.

To Reproduce
Steps to reproduce the behavior:
Just run a simple sudo timeshift --check o sudo timeshift --create to always get the error message.

Expected behavior
It should allows me to take snapshot as per app goal.

Screenshots
I attach a log of a create command.

I'm running Timeshift on an RPi Model 4-8GB running Raspberry Pi OS Buster and I'm seeing basically the same issue only mine says Live USB Mode. Have you figured out how to get the Create button enabled?

Nope. I ended up using BackInTime.

same issue, timeshift cli arch linux

I am having the same issue with my Raspberry Pi 4b 1Gb. However, I am also using berryboot to dual boot two versions of raspbian, so that may be the issue in this case.

I think it just does not support linux arm64. Hope it can be fixed soon.

Okay, Ive fixed it, kind of. i just installed it from the AUR and cleared all my cache instead of compiling from source (rip if your not using arch :(.)
