Looks Like the kernel is pinned in some LXC.
Like the Message say, Check it or remove manually

I have the same problems on clean Proxmox 8.3.2 installations.
only manual deletion takes effect

I used these steps - after a GOOGLE search and was able to clean-up all the old Kernels (I got rid of all of them - except 'one back' from current).

To remove an old Proxmox kernel, use the command apt purge <kernel-package-name> in your terminal, where <kernel-package-name> is the specific package name of the old kernel you want to delete, which will usually be in the format "proxmox-kernel-x.x.x-pve".

Key steps:

  • Identify the old kernel: Use dpkg --list | grep proxmox-kernel to list all installed Proxmox kernels and identify the one you want to remove.
  • Remove the kernel: Execute the command sudo apt purge <kernel-package-name> (sudo is not needed if you are already logged in as 'root' and launch the )

Important considerations:

Always keep a backup kernel:
Before removing an old kernel, ensure you have at least one other functional kernel available on your system.
Check for dependencies:
Use apt autoremove after removing the kernel package to clean up any associated dependencies.

@jakemauer commented on GitHub (Dec 27, 2024):

I'm currently running Proxmox 8.3.2 with kernel 6.11.0-2-pve and am unable to remove old kernels. For example I get errors like: `Failed to remove kernel: proxmox-kernel-6.8.12-4-pve-signed. Check dependencies or manual removal``

When I attempt to manually remove a kernel using apt purge it attempts to remove the old kernel but then halts with the following error:

W: (pve-apt-hook) !! WARNING !!
W: (pve-apt-hook) You are attempting to remove the meta-package 'proxmox-ve'!

And then I obviously don't proceed. These errors occur for all three of the older kernels still on my system.

Thanks. Also finding the script would not remove anything at all. Removed them manually with your instructions no issue.

I'm getting the same issue after updating to 8.3.2 today. This is the first time I've had issues with this script, and no LXC has the kernel pinned.
I'm not sure why the issue was closed.
