Q{"Paid<br/>subscription?"} -- No --> A["Disable enterprise repos<br/>Enable no-subscription"] --> U["Update + reboot"]
Q -- Yes --> K["Keep enterprise<br/>Add key in UI"] --> UProxmox VE 9 runs on Debian 13 (Trixie) and keeps apt sources as deb822 files
in /etc/apt/sources.list.d/.
1. Repositories (no subscription)¶
Enterprise repos return 401 without a key. Skip this step if you have a subscription.
Enabled: false stays inside the stanza
A blank line before it starts a new stanza and apt reports

2. Upgrade¶
apt-get update
DEBIAN_FRONTEND=noninteractive apt-get -y dist-upgrade
pveversion
Hit:1 http://deb.debian.org/debian trixie InRelease
Get:2 http://download.proxmox.com/debian/pve trixie InRelease …
…
pve-manager/9.2.x/… (running kernel: …)
apt-get update must finish with no 401 or Malformed stanza.
3. Reboot if the kernel changed¶
If pveversion shows an older running kernel than the one just installed,
reboot.
reboot
# once it is back:
pveversion
pve-manager/9.2.x/… (running kernel: <new version>-pve)
