I have a problem with the app manager - simply I can't install or uninstall anything and when I try to update the list of application to download or update it tells me that there are no applications or updates. When I type "apt-get clean" in terminal I get an error: "E: Lists directory /var/lib/apt/lists/partial is missing". What's going on? It started suddenly and I don't think I installed anything dangerous recently.
root mkdir -p /var/lib/apt/lists/partial
