I was trying to install VirtualBox and when running the GDebi package installer my internet connection gave up and the installation got 'stuck'.
Now i realize none of the package managers are working...
Synaptic, apt-get, update-notifier, GDebi.
I get this error with Synaptic:
An error occured.
The following details are provided.
E: The package virtualbox needs to be reinstalled, but I can't find an archive for it.
E: Internal error opening cache (1). Please report.
