Proxmox Automatic Updates

It's propably better to start a new thread and include any relevant information aka error messages/logs
sadly i dont have logs :/
the command works manually but if i set crontab -e for every few hours and wait a few days no update is applied / upgraded :(
and this is the first Thread showing up in the websearch results
so i thought it would be nice if its up to date :)
 
The file looks valid but pveupgrade doesn't seem to be designed to run non-interactively. I think it can ask for confirmation, for example.
Have you tried checking the journal to see what it says around that time?
If you really want to test I'd set it to run every minute and then follow the logs via journalctl -f. You can also pipe (append) the output into a logfile
pveupdate is already scheduled to run via pve-daily-update.timer.
That said, dont. I generally do my main updates/upgrades manually (via ansible, mostly) but let my systems notify me about them with this.
I also use unattended-upgrades for security updates but that was mentioned already.
No need to quote a message you're directly replying to, by the way.
