As mentioned earlier in this chapter, in the recent Proxmox release, owing to a bug in the software, upgrading through the GUI caused some issues. The GUI is basically the frontend of the behind the scene commands that are run through Proxmox scripts. But still, updating or upgrading Proxmox through the CLI seems to be the safest path.
There are no special Proxmox-specific commands to update a Proxmox node. The standard apt-get
for all debian
-based distributions is used for the updating process. Log in to the Proxmox node directly on the node or through SSH, and then run the following command to update the list of new packages, as follows:
# apt-get update
After the package database is up to date, we can start the update process using the following command:
# apt-get dist-upgrade
