/boot is full can't remove old kernel, cause dependencies of new failed install

[prokop1000]

Hello! distupdate failed due dependencies, cause /boot is full!
I found on the forum, how to remove old kernels, but when I want to remove it with purge, remove or autoremove, I got the following error

sudo apt-get autoremove linux-image-2.6.32-28-generic-pae
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-image-generic-pae : Depends: linux-image-3.2.0-41-generic-pae but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).


How can I solve the problem ?
thanks

prokop1000; Hi ! Welcome to the forum >

There are solutions, and then there are solutions. Let's take a look and see why you think you are short of operating head space.
Post back the output of the following terminal command as it is useful for finding out which directories are using all your space...

du -h --max-depth=1 | sort -hr

Once operating room is obtained, we can look at the other problems.

just try'n to help

Hi!

Thanks!

There are a few linux-image installed:

linux-image-3.2.0-35-generic-pae linux-image-3.2.0-40-generic-pae

I think this might be the problem, am I wrong?

There are many ways to remove old kernels. Seems everyone has a pet way to do it :)

My pet way is Synaptic Package Manager

prokop1000; Hey.

Yeah, your /boot partition is 100% full. Remove all but the latest 2 images and headers.
Terminal codes:


dpkg -l | grep linux-image-
sudo apt-get purge linux-image-2.6.32-{28,41,42,}-generic-pae
sudo apt-get purge linux-headers-2.6.32-{28,41,42,}-generic-pae
I would expect there to be many more kernel images/headers than this, remove all of them-less the two latest- using this format.

As you have encrypted file system, I can not really relate as to what is happening in the /root directory - 94% full -> no operating overhead there also - need to do some trimming for sure.
When all done with removals, run terminal command:

sudo apt-get --purge autoremove

regards

[prokop1000]

Thank for the answer, but the problem is, that autoremove will fails cause of the dependency

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
linux-image-generic-pae : Depends: linux-image-3.2.0-41-generic-pae but it is not installed
E: Unmet dependencies. Try using -f.

and not removing the old images. Since images are not removed -f install fails. catch 22

[prokop1000]

solved it, by moving manually the files /boot/initrd.img-2.*-*-generic-pae to a temp directory, then run apt-get -f install. When it finished with success (since it has space now in /boot), I removed some images I did not move from /boot. After it I moved the files back to /boot from temp and removed it with as well with apt-get.
