I am trying to build Wine from source on an X64 Hardy Ubuntu system in order to do some regression testing. I am having trouble however to build the dependencies for that. I already did these a while ago, but I re-applied just in case the instructions from this page for the apt repository http://www.winehq.org/site/download-deb. I constantly get this error: xavier@Xavier:~$ sudo apt-get build-dep wine [sudo] password for xavier: Reading package lists... Done Building dependency tree Reading state information... Done E: Build-dependencies for wine could not be satisfied. I tried another command, and here is the result. xavier@Xavier:~$ sudo apt-get --build source wine Reading package lists... Done Building dependency tree Reading state information... Done Need to get 18.7MB of source archives.

But how is it that even when the apt repository is in my sources list, the dependencies cannot be met anyways?
