Thanks, this helped me figure out what was wrong. I had installed the program "upgrade-system" (from Konflux) to try it out. I believe this program created the etc/apt/preferences file, which gave high priority to stable, and low priority to everything else. I don't actually need this, since the unstable repositories are currently not active in my sources.list. So, removing upgrade-system, and deleting the preferences file has returned things back to normal. It's good to know that the option of having a mixed sources.list exists though.Look into "apt-pinning". you can "pin" a particular package to a specific version and control what apt does with it. something like: Package: freemind Pin: release a=experimental Pin-Priority: 1001in your /etc/apt/preferences file should do it. man apt_preferences. you could also specify a version withPin: v=0.8.0 A
