[elbe-devel] [PATCH v2 14/22] virtapt: add apt_pkg.DepCache member and mathods using it

[Bastian Germann]

Typo in the title (mathods -> methods)

> make virtapt more similar to how RPCAptCache works.
> 
> the only user "elbe check_updates" has the DepCache as private variable
> currently. But, for downloading of packages, the DepCache is also needed.
> 
> Create self.depcache and read the pinning file, which is already generated
> by the VirtApt constructor.
> Then add methods, taking pkgnames as parameters.
