Can't remove pve-kernel-5.15.116-1-pve Package in Debian 11

[Adrianozk]

Hello Proxmox community,

I'm currently facing an issue when trying to remove the `pve-kernel-5.15.116-1-pve` package on Debian 11. Here's the context of my problem:

- Operating System: Debian 11
- Context: I initially attempted to install Proxmox alongside OpenMediaVault (OMV) on this Debian 11 system. However, I encountered an error during the installation process, and my primary issue now is related to removing the problematic package.

Issue Description:
I attempted to remove the `pve-kernel-5.15.116-1-pve` package using the following command:

sudo dpkg --remove --force-remove-reinstreq pve-kernel-5.15.116-1-pve

However, I received the following error:

Removing pve-kernel-5.15.116-1-pve (5.15.116-1) ...
Examining /etc/kernel/postrm.d.

Errors were encountered while processing:
 pve-kernel-5.15.116-1-pve
Processing was halted because there were too many errors.
E: Sub-process /usr/bin/dpkg returned an error code (1)

I've tried installing proxmox-kernel-helper as suggested by others, but it didn't resolve the issue. It seems like the post-removal script for pve-kernel-5.15.116-1-pve is encountering problems.

If anyone has encountered a similar issue or has any insights on how to resolve this, your assistance would be greatly appreciated. My goal is to successfully remove the pve-kernel-5.15.116-1-pve package from my Debian 11 system.

Thank you in advance for your help!

I wanted to share the solution that worked for me regarding the removal of the pve-kernel-5.15.116-1-pve package on Debian 11.

Here's what worked for me:

1. I commented out the /var/lib/dpkg/info/pve-kernel-5.15.116-1-pve.postrm file to prevent the post-removal script from running during removal.
2. I ran the following command to forcefully remove the package:
   sudo dpkg -P --force-all pve-kernel-5.15.116-1-pve
3. Then, I ran the following command to fix any broken dependencies:
   sudo apt --fix-broken install

This successfully removed the problematic package from my Debian 11 system.

I hope this solution helps others who might encounter a similar issue. If you have any questions or need further assistance, please feel free to ask.
