If you don't pay for support,. you don't have access the subscription repos that are configured by default. Then you need to go into Updates - Repositories and turn off the subscription repos and add the non-subscription repo instead. You can then manually update there. https://pve.proxmox.com/pve-docs/chapter-sysadmin.html#sysadmin_no_subscription_repo
(Anything you wonder about in Proxmox, just click the Help button top right, it takes you to the relevant section in the manual at all times).
As for auto upgrading, not sure I would ever want that. I don't know if Proxmox has anything above regular Linux/Debian methods you can easily configure.
Hi Neobin,
I am using No-Subscription Repository.
When I log in to proxmox on the server I get the message "No valid subscription". I am looking for a solution to disable it
Thanks for the response.
