That's an Ubuntu packaging problem. Wine developers provide only source for the program and don't do any packages for distributions also winetricks is a separate project. You could install the latest version of winetricks by yourself without any packaging. I'm doing it this way: wget http://winetricks.googlecode.com/svn/trunk/src/winetricks sudo cp winetricks /usr/bin if it's not working you probably need to make it executable: sudo chmod +x /usr/bin/winetricks When you want to update it you have to remove the old winetricks because if you don't the new downloaded with wget will be named winetricks.1 rm -f winetricks or delete it from file manager (Nautilus, Dolphin) and then repeat the above steps. This way you always have the latest winetricks with updates and new recipes (for example for dotnet40 or rayman2_demo).
