I had issues with the PVE web portal after these updates (no issues with SSH, VMs or containers):


Bash: 
Start-Date: 2025-09-29  21:49:31
Commandline: apt-get dist-upgrade
Install: proxmox-kernel-6.14.11-3-pve-signed:amd64 (6.14.11-3, automatic)
Upgrade: proxmox-widget-toolkit:amd64 (5.0.5, 5.0.6), pve-firmware:amd64 (3.16-4, 3.17-1), proxmox-kernel-6.14:amd64 (6.14.11-2, 6.14.11-3), libpve-common-perl:amd64 (9.0.10, 9.0.11)
End-Date: 2025-09-29  21:49:54

In browsers (Chrome,Edge,Librewolf) I would just get a blank page. Dev tools revealed errors:
Failed to load resources, no such file '/PVE/StdWorkspace.js'

After rolling back the updates I could access the web interface again. Not sure how to troubleshoot this further,
 
Hi @uppsju , welcome to the forum.

Out of curiosity: what do you mean "rolling back the updates"?

You best way to troubleshoot the situation is by reaching out to the authors of the PVE modifications that you likely installed to remove a reminder that non-subscription repository is not suitable for production.

The best way to avoid such situation in the future is by not installing out-of-tree modifications if you don't fully analyze what they do, and how they affect you.

Hi @bbgeek17 , thanks! By rolling back the updates I mean I had to SSH to the node, then using the standard apt install package=version to downgrade to the old version mentioned in the apt log. I've had no issues with previous updates, such as upgrade from PVE 8 to 9, or any of the minor point releases up until today.
I did try some other suggestions that I saw from other (older) forum posts with similar web portal issues, such as re-installing the proxmox-widget-toolkit, also checking network issues etc. But it seems the only casualty from the update was the web portal itself, no issues with VMs or LXC containers or other functionality of PVE.
