Warnings (and how to get rid of them) upgrading from 7 to 8

[LeChuck71]

Hello everyone,

I am going to upgradea my current Proxmox 7.4-19 to 8 but I struggle a bit with the precheck and its results.

INFO: Checking bootloader configuration..
WARN: System booted in uefi mode but grub-efi-amd64 meta-package not installed, new grub versions will not be installed to /boot/efi! Install grub-efi-amd64.
INFO: Check for dkms modules...
WARN: dkms modules found, this might cause issues during upgrade.
SKIP: NOTE: Expensive checks, like CT cgroupv2 compat, not performed without '--full' parameter

root@proxmox:~# dkms status
pivccu, 1.0.84: added

I have two warnings:
1. grub-efi-amd64
2. DKMS module pivccu

As I have no deeper understanding on Linux I was wondering how to get rid of the two warnings. So I did some research and came to this souluttion

1. Install correct grub

[ -d /sys/firmware/efi ] && apt install grub-efi-amd64

2. Remove DKMS module pivccu (dont need it - possible from an old Homematic installation)

dkms remove pivccu/1.0.84 --all

I am not sure if this is correct so I would greatly appreciate it if I can get a verification

Thx for all your help

Hi,

the easiest way to confirm is to run the pve7to8 tool again, if everything is fine, the warnings should be gone

Yeah that is correct I was just wondering if the commands I posted are the correct ones to solve the two warnings

yes, installing the package with apt is the right way, and if you remove the dkms module it can't fail anymore
(it depends on how you installed the dkms module in the first place, but if you added it straight with dkms, then removing it the same way is correct)
