Hi guys,

I have running a few Debian machines migrated to VZ containers (none native VZ container installations).

Now when trying to upgrade the existing packages by using apt-get upgrade, it's not possible because of the original installed kernel packages.
For an example, one of the Debian machine:

apt-get upgrade
Reading package lists... Done
Building dependency tree

The following packages will be REMOVED:
linux-image-3.2.0-4-amd64
The following packages will be upgraded:

un linux32 <none> (no description available)

The following kernel version will be used by the VZ container:

uname -a
2.6.32-042stab108.8 #1 SMP Wed Jul 22 17:23:23 MSK 2015 x86_64 GNU/Linux

To exclude the kernel package within the upgrade process I set the following package on hold:

apt-mark hold linux-image-3.2.0-4-amd64
linux-image-3.2.0-4-amd64 set on hold.

apt-mark showhold
linux-image-3.2.0-4-amd64

Now I get another error when trying to run apt-get upgrade:

apt-get upgrade
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-3.2.0-4-amd64 : Depends: linux-base (>= 3~) but it is not installed
Recommends: firmware-linux-free (>= 3~) but it is not installed
E: Unmet dependencies. Try using -f.

Therefore I would ask you how to proceed to get the upgrade working without upgrading the installed kernel packages?

Thanks,
Philipp

I would recommend uninstall linux-image, linux-base packages.

it maybe more dependencies but using common sense you can remove dependencies as well.
