Ubuntu
bleachbit package

Please could you advise which of the following kernels I may remove, and the terminal commands to do so

Asked by jegpad

Hi there, I'm using over 70% of my installation drive and need to free space. I will use Bleachbit (with safer settings than last time when I deleted irrevocably all my Amazon account history and other stuff) but saw in a previous Q&A that old kernels may be deleted. Please could you check out this read out and advise what commands I can run in terminal to free up some space. Many thanks in advance...

sudo apt-get --purge remove `dpkg -l | awk {'print $2'} | grep -v linux-image-generic | grep -v 3.2.0-29`

In short, you remove any kernels which aren't running and not the 'linux-image-generic' package.

Thanks HeadVeg, that's done the trick. FYI, found main reason drive was full was a number of undeleted *.iso files. Hmmm.

Hi jegpad. I know, that you've solved this "problem", but I think, that you should/could also remove for example 'linux-headers-3.2.0-36' package and so on, besides normal 'linux-image' package.

,-----[ an example ]
| sudo apt-get --purge remove linux-headers-3.2.0-36

Cheers.

Hi jegpad. It is just about that, with the removal only of 'linux-image-generic', 'linux-headers' are not removed automatically, but also takes a lot of disk space.
