Enable Updates In Proxmox Without a Paid License
In Proxmox we can enable updates via apt without a paid license.
Establish a shell on your Proxmox server. Replace pve with the hostname or IP address of your Proxmox server.
ssh root@pve
I’m going to use vim to edit files, but nano is a better choice if you aren’t familiar with vim.
Edit your sources.list file.
vim /etc/apt/sources.list
Add this.
# pve-no-subscription repository provided by proxmox.com, not recommended for production use
deb http://download.proxmox.com/debian/pve buster pve-no-subscription
Edit your pve-enterprise.list file.
vim /etc/apt/sources.list.d/pve-enterprise.list
Comment out the single entry there.
#deb https://enterprise.proxmox.com/debian/pve buster pve-enterprise
Run the following commands.
wget http://download.proxmox.com/debian/proxmox-ve-release-6.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg
sha512sum /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg
apt update
That’s it.
Perform a distribution upgrade if you wish.
apt dist-upgrade
Get to work.
