Autoremove does not remove old headers

772

I have a 16.04 installation with a weird problem

sudo apt autoremove

removes old kernels except the current and a previous, but does not remove old headers.

On other 16.04 installations it removes both.

How can I find out what is wrong?

I've spent a lot of time on learning how kernel autoremove works, but did not find any differences between working and non-working machines.

After the previous run of apt autoremove all linux-image packages have been removed except 4.4.0-42 and 43, but the headers are kept.

This is the debug-autoremove.txt from the affected installation.

autoremove will remove any package that:

is auto installed
is not included in APT::NeverAutoRemove APT configuration
don't have any dependents

Here is the debuging steps we followed

Checked auto/manual installation
```
aptitude search '^linux* ?installed'
```
Checked currently declared versions under APT::NeverAutoRemove
```
cat /etc/apt/apt.conf.d/01autoremove-kernels
```

Checked dependency

apt-cache rdepends linux-headers-4.4.0-38-generic

brings nothing but

sudo apt-get -o Debug::pkgAutoRemove=1 -s autoremove 2> debug-autoremove.txt

So it's a dependency issue through the virtual package linux-headers

I'm in doubt here, It seems to me as bug.

Either in autoremove function, it can't deal with virtual package dependency.
Or in virtualbox package, that may need another way to declare dependency to Linux headers.

I generally do not trust much in automatically running system maintenance actions when it comes to important topics like kernel management. As I can see from your comments, there seems to be an interference with VirtualBox 5. So I recommend the most reliable way to clean up old kernels.

Check which kernel versions are installed : dpkg --get-selections | grep linux

To check especially for headers : dpkg --get-selections | grep linux-headers

Remove the ones you want to get rid of (replace * with the kernel version number) :

sudo apt purge linux-headers-* linux-headers-*-generic linux-image-*-generic linux-image-extra-*-generic linux-signed-image-*-generic

This is of course not an explanation what went wrong and why the automatic headers removal does not work when running the apt autoremove command, but in the end it is a solution to achieve what you want and it additionally makes sure that everything is cleaned up properly.
