How to update appliances

[bigbang]

I have three appliances based on Ubuntu. How do I update them?
I do not see a button for that in the GUI.
Do I have to update each one of them at the command line once they are running?
I searched everywhere I could without success.

I just upgraded my Proxmox VE to 7.4 without difficulty.

You neither told us what those appliances are, nor if you run them in a VM or LXC.
You should have a look at the documentation of those appliances. They usually will have a whole chapter on how to do major and minor upgrades.

I should have mentioned that they are LXCs .
I used the CT template Ubuntu 22.04 from Proxmox for all three. My question relates to updating those three Ubuntu setups. Two of them have additional software, the last one has none yet.

sudo apt update && sudo apt upgrade && sudo do-release-upgrade -d to upgrade a ubuntu to the next major version.

So I have to update EACH container individually (instead of asking Proxmox to do a group operation). That is what I was looking for.

Thank you for your quick help.

PVE just provides the virtual hardware, it doesn't manage the guest OSs. Moat of the LXC templates don't even come from proxmox but feom third parties.

You could try something like ansible to bulk manage your guests.
