Please provide detailed steps to reproduce the issue.

1. check kernels via "dpkg --list|grep proxmox-kernel.-pve." - 6 in total, one iU, one not installed due to lack of disk space (6.8, tat's why I'm trying to clean it up), 4 more marked as ii
2. execute the script (as of 27.11) via bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/misc/kernel-clean.sh)"
3. reboot
4. check kernels via dpkg --list|grep proxmox-kernel.-pve.

Expected: the list after 4 will differ from that in step 1
Actual: the list is the same
I had to uninstall them manually via dpkg -P that worked just fine
