Are there recommend steps to apply patch for Debian/Proxmox VE vulnerability?

[devleti]

First of all, I'm a newbie to this program, so my questions might be very basic.

1. If Debian has vulnerability, I usually apply patch with apt-get update, apt-get upgrade, reboot (if needed). Is it the same for Proxmox VE?
2. Are there recommend steps when applying patch for Debian/Proxmox VE vulnerability?

Thank you.

PVE is build on top of debian so it works much the same way. See docs here. Don't use upgrade.
There's also the pveupdate and pveupgrade CLI tools and you can update via node > Updates in the GUI too.

upgrade should be dist-upgrade but yes, I would however change over to apt instead of apt-get. If you use apt-get, you would need an additiona apt-get clean to remove the downloaded packages, apt does this automatically.

No, upgrades to PVE are also dpkg based, so running apt will also install them. Restarting the VMs could be necessary, depending on the updates.
