[SOLVED] Older Linux Kernels

Post by Ragz »

Where are the older Linux kernels and how does one go about deleting them?

Hi, Ragz.

Launch Update Manager. Go to View => Linux-Kernel.
Locate all the (old) kernels, which Update Manager labels as "installed". Delete them by clicking on [Remove]. Update Manager will cleanly uninstall them.

The kernel location on your filesystem is /boot. But what you see there, the boot image files and the kernel files, are only a part of the truth, because the kernel installation packages bring along some more files than only the loadable kernel. So permit Update Manager to do the removal.

HTH,
Karl

What is the norm to keep at one time?

Hi, Ragz.

There is no strict norm. Yet, frequently, you will be advised to keep
+ the currently active kernel (obviously, you cannot uninstall it while it is running)
+ the previously used kernel (just for the case that the new kernel should start causing serious problems suddenly)

Personally, I usually keep a minimum of 3 generations. But this is just me.

Regards,
Karl
