Grub Error after every update

[knozturk]

I am new to proxmox but I have been doing update since 6.x. Now I am getting the following error after updates. I am currently at latest version of 8.x

Hey,

what error do you mean? Is something not working?

It is only a warning. Please have a look at "/etc/default/grub". Maybe "GRUB_DISABLE_OS_PROBER" is on "true". This is only needed on dualboot systems.

Another good idea is to uninstall unused kernels and software packages. You can do this with the following command:

apt autoremove --purge

Now I am getting the following error after updates.
