Management of old Kernels and Boot Entries

[Noah0302]

Hi guys,

I was wondering how you handle old Kernels and Boot Entries in your Proxmox Host(s).

I usually keep one or two older Kernels, in Case I encounter Problems with the latest Kernel, similair to this Screenshot from another Forum-Post:


Do you even keep older Kernels, or do you just remove them, as soon as APT marks them for Removal?


Thanks for reading!

I install all upgrades when they come out and if there is a kernel upgrade I will reboot the node as soon as possible when there is a maintainance window.
Then I test if everything is still working and then I run the apt autoremove to remove the old kernels. PVE will make sure the last kernel and a very old kernel will be kept as a fallback option.

So the old Boot-Entries will still be availible, even if

apt autoremove

removes them?

If yes, thats exactly what I want.

No, what apt autoremove removes won't be available anymore. But apt autoremove won't remove all old kernels. It will always keep some recent and very old kernels back. An apt autoremove will show you what would be removed and you can then decide to continue or not.

Thank you for the explanation!
