computer-janitor needs option to remove unused linux kernels/headers

[Reynaldo Horsford (reynaldo-horsford)]

Yes, the Janitor basically does not find/remove any residual config files after packages are removed. I still use synaptic to remove these file as Computer-Janitor reports "Nothing was found to clean up". This would be a good function to add in keeping with the purpose of the tool.

I am on Ubuntu Desktop 64bit 2.6.28-15-generic. I have found that after my initial install and first upgrade from repositories that Janitor had included old kernel headers.

@yurik81, which version of computer-janitor do you use on which version of Ubuntu?

[yurik81 (yurik81)]

I am using latest version of computer-janitor (1.13.3-0ub) on Ubuntu 9.10 beta.

[yurik81 (yurik81)]

Another good idea would be to add options to clean apt cache and removing packages marked for automatic installation, that no longer in use.

I've just verified that computer-janitor, in karmic, does indeed suggest linux-headers-* and linux-image-* for removal.

I also verified that it still suggests packages that "apt-get autoremove" (packages marked as automatically installed, but nothing depending on them anymore).

For cleaning the apt cache, please file a wishlist bug.

With Ubuntu 9.10 installed afresh in double-boot (vista) and then updated, the computer has kernels 2.6.31-14 & 2.6.31-20.

9.10 installs grub-pc, which generates a menu with both kernels (& vista).

Computer-janitor 1.13.3 (which btw reports 1.11 in Help/About) offers to remove linux-headers-2.6.31-14 & linux-headers-2.6.31-14-generic, but not linux-image-*.

Consequently, when the selected tasks are executed, Computer-janitor finds no further packages to remove, but update-grub still finds 2.6.31-14 and generates a menu for both kernels:

Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.31-20-generic
Found initrd image: /boot/initrd.img-2.6.31-20-generic
Found linux image: /boot/vmlinuz-2.6.31-14-generic
Found initrd image: /boot/initrd.img-2.6.31-14-generic
Found memtest86+ image: /boot/memtest86+.bin
Found Windows Vista (loader) on /dev/sda1
done

It is possible to boot on either of the kernels.

I expected 2.6.31-14 to be removed completely from the computer, and grub updated by Computer-janitor to reflect this.
