[Pkg-virtualbox-devel] Bug#630772: dkms: "Use of uninitialized value" perl warning when removing a kernel with virtualbox modules

[Raphael Hertzog]

Package: dkms
Version: 2.1.1.2-6
Severity: normal

When removing an obsolete kernel, I got 6 warnings like this one:
Use of uninitialized value $command in lc at /usr/share/perl5/Debconf/ConfModule.pm line 123, <GEN0> line 3.

I don't know if dkms is at fault or if it's virtualbox that is not using dkms correctly.
See the log below:
