update/upgrade issue with kernel PMG 7

[bogdan.kulish]

Hi, I have PMG 7
After some update, I don't remember exactly which. I get errors when updating the kernel. Also, these errors appear when I want to upgrade from version 7 to version 8. When I try to configure the kernel, update, I get the same errors.

uname -r

Did you install on top of Debian? In that case it is recommended to use the proxmox kernel and remove the default debian kernel. Also, please follow the upgrade guide carefully and execute also the pmg7to8 helper script, see https://pmg.proxmox.com/wiki/index.php/Upgrade_from_7_to_8

Did you install on top of Debian? - I don't know, because this was done by the previous specialist, most likely, yes. Let's assume that it is installed on top of Debian.
Yes, I use the instructions, I have already updated one different PMG according to the instructions, but I have problems with this.
Please advise me on how to check which kernel is for the proxmox kernel, and how to remove the ones that are not needed?

Please try apt remove linux-image-amd64 && apt update && apt dist-upgrade

it seems /etc/kernel/postrm.d/proxmox-auto-removal doesn't allow to remove this

I managed to fix it, maybe a little rough, but everything worked.
these files did not allow me to delete the kernel via apt
removed files
/etc/apt/apt.conf.d/01autoremove
/etc/apt/apt.conf.d/01autoremove-kernels

removed folders
/lib/modules/5-*-amd64
/lib/modules/4-*-amd64
/boot/linux-image*-amd

did not delete the folders/files
/lib/modules/*-pve
/boot/*-pve

apt-get --purge remove linux-image-*-amd64
dpkg --purge linux-image-*-amd64

apt reinstall gdisk proxmox-kernel-helper pve-firmware pve-kernel-5.15 pve-kernel-5.15.158-2-pve
apt reinstall proxmox-mailgateway

after these manipulations everything updated without problems.
I hope this helps someone.
