Proxmox Update Error bullseye InRelease 401 Unauthorized [IP: 443]

Are you getting this error in Proxmox while trying to apt update or install Ceph?

apt update
Hit:1 bullseye-security InRelease
Err:2 bullseye InRelease             
  401  Unauthorized [IP: 443]
Hit:3 bullseye InRelease                       
Hit:4 bullseye-updates InRelease
Hit:5 bullseye InRelease
Reading package lists... Done
E: Failed to fetch  401  Unauthorized [IP: 443]
E: The repository ' bullseye InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.


This error is caused by not having an enterprise Proxmox subscription/license. However, Proxmox can use Free/Testing/Non-Enterprise packages for Ceph.

For older versions of Proxmox like 7.1

This is normally caused by the fact that you don't have an Enterprise Subscription, either update your subscription or comment the Enterprise repo out in /etc/apt/sources.list.d/pve-enterprise.list

Alternatively you can simply just delete /etc/apt/sources.list.d/pve-enterprise.list and you'll be ok.

Here is how /etc/apt/sources.list should look (assuming you are using Bullseye):

deb bullseye main contrib

deb bullseye-updates main contrib

# security updates
deb bullseye-security main contrib


Here is how /etc/apt/sources.list.d/ceph.list should look:

deb bullseye main


For newer versions of Proxmox (eg. 8+)

You may also need to enable the no-subscription repo:

sources.list for version 8 of Proxmox with no-subscription repo:

deb bookworm main contrib
deb bookworm-updates main contrib

# Proxmox VE pve-no-subscription repository provided by,
# NOT recommended for production use
deb bookworm pve-no-subscription

# security updates
deb bookworm-security main contrib

Also edit /etc/apt/sources.list.d/ceph.list

deb bookworm no-subscription
