Let’s take a closer look at defining the steps to remove old kernels from the Proxmox system. At Bobcares, with our Proxmox Support Service, we can handle your issues.

Steps to Remove Old Kernels from the Proxmox

It’s critical to find out which kernels are present on the Proxmox system before deleting old kernels. We can use the following command to get a list of current kernels:

Now, we’ll get a list of the current kernels in use. In order to remove the old ones, we must carry out the following steps:

1. Make sure we’re not deleting the kernel that the system is using at the moment. While deleting old kernels, be sure to leave the current one running. To find out which kernel is currently in use, run:

2. After choosing which old kernels we need to get rid of, we can use the apt package manager to uninstall them. We can use the below command for all the kernels we want to remove:

3. We may also want to remove the related header packages and other items in addition to the kernel image packages. The same apt remove command can be used for this, but with the proper package names.

4. Updating the GRUB bootloader config to reflect any changes made after uninstalling older kernels is a good idea. To upgrade GRUB, run:

Using the installed kernels as an outline, this command will recreate the GRUB config file.

5. Rebooting the Proxmox system after deleting outdated kernels and updating GRUB is a good idea, but it’s not always required, to make sure that the changes take effect.

6. Rebooting will allow us to confirm that the old kernels have been successfully removed by listing the installed kernel packages with the following command.
