How to: Upgrade from Proxmox 6.1 to Proxmox 6.2 (PVE)

Last Updated on

Make sure you have backup before upgrading if you are using Proxmox free/community version

1 Edit “/etc/apt/sources.list” to add Proxmox VE No-Subscription Repository (If haven’t done so)

nano /etc/apt/sources.list

Add following lines to the bottom of the file (For no-subscription users/community/free) [1]

# PVE pve-no-subscription repository provided by proxmox.com,
# NOT recommended for production use
deb http://download.proxmox.com/debian/pve buster pve-no-subscription

For Proxmox VE Enterprise users, add following lines instead [1]

deb https://enterprise.proxmox.com/debian/pve buster pve-enterprise

(The final version looks like following)

deb http://ftp.au.debian.org/debian buster main contrib
deb http://ftp.au.debian.org/debian buster-updates main contrib
#
# security updates
deb http://security.debian.org buster/updates main contrib
#
# PVE pve-no-subscription repository provided by proxmox.com,
# NOT recommended for production use
deb http://download.proxmox.com/debian/pve buster pve-no-subscription

Use, Ctrl + X, Y, Enter keys to Save and Exit

2 Open terminal from Proxmox host or via SSH

Use following command to upgrade Proxmox VE

apt update && apt dist-upgrade

(We can also login to Proxmox VE web gui, Navigate to Datacenter -> node/cluster Name -> Updates, click on “Refresh” then click on “>_ Upgrade”)

3 Restart Proxmox host

(Make sure there is no virtual machines running)

reboot

4 Now, we have Proxmox 6.2 running if the upgrade succeeded
