View Full Version : [ubuntu] /boot partition filling up quickly need to delete old kernels

July 6th, 2011, 07:15 PM
how would i go about deleting my old kernel? i have my ubuntu machine partitioned the way gentoo would partition a drive with a seperate boot directory. my boot directory is only 200 megs so i can probably fit 4 kernels max into it and need to eject the old ones.

I suggest next time you install, you get rid of a separate /boot partition, as it complicates things for most situations.

However, for now, you can remove old kernels most easily by using synaptic, search for the kernel number, eg 2.6.32-31, 2.6.32-29 etc etc, and remove all the packages with those exact old numbers, usually a linux-image and two linux-headers packages. It's best to keep the most recent and the one before that, just in case.

Here are some other ways to remove them, including via the GUI app Ubuntu Tweak:

not as urgent as you were expecting. simple maintenance question.... if i was REALLY in a pinch for space i would of rm -rf /boot/imagetoberemoved because i operate that way and am strugling with debian package management and can not get a source debed for the life of me

as a rule (and good nix practice) it is unadvisable to "rm -rf" anything - a little like shooting pigeons with buckshot :p.
sudo rm /boot*2.6.32.nn*

where <2.6.32.nn> is the kernel number - [starting with the lowest number first]

will remove the specific number related kernels in group format (config, vmlinuz etc) - typically linux - many ways to skin the cat.
