Picking 'tiff3' as source package instead of 'libtiff4'
E: Unable to find a source package for tiff3
If I add -f, it doesn't change the behavior. What is causing it to do this and how do I force it to download the package I want?
Based on a search, I can't even tell where it is getting the idea of tiff3
