I have a Linux Mint 17.1 Rebecca - Release amd64 20141126]/ trusty contrib main non-free installed, and the apt-get install wine wont do the trick. it returns the following:
Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: wine : Depends: wine1.6 but it is not going to be installed E: Unable to correct problems, you have held broken packages.
then I tried everything I found on this thread here
I disabled, and removed all ppa-s.
still I cannot install wine (nor skype)
