Error "version specified in config file is not an int" when checking

[collioud]

Describe the bug
Got this error when running command autorestic check:

Using config: 	 /home/collioud/.config/autorestic/.autorestic.yml
Using env:	 /home/collioud/.config/autorestic/.autorestic.env
version specified in config file is not an int
Using lock:	 /home/collioud/.config/autorestic/.autorestic.lock.yml

I tried with a full config file, or just with a one-line config file (echo "version: 2" > .autorestic.yml)... Got the same error.

Expected behavior
Check of config file without error.

Environment

• OS: Ubuntu
• Version: 24.04 (amd64)
• shell: zsh 5.9 (with zprezto installed)
• autorestic: 1.8.3
• restic: 0.17.3 compiled with go1.23.3 on linux/amd64

Additional context
This happens with an installation "from scratch". Tested also with autorestic 1.7.11 : same error.

Thank you for your help!
Best regards,
