(Couldn't do it using synaptic, but found some help in backing it out on the appdb page for WoW: http://appdb.winehq.org/objectManager.php?sClass=version&iId=24878) sudo apt-get remove wine1.5 && sudo dpkg -i `find /var/cache/apt/archives/ | grep "wine" | grep "1.5.4"` This command worked for me. Would still appreciate an answer to my original question, if there's someone with more knowledge of Synaptic who can help out.
