Something is still wrong? I got still following messages: Building dependency tree Reading state information... Done libqtm-11-location is already the newest version. qtquickcompat is already the newest version. You might want to run `apt-get -f install' to correct these: The following packages have unmet dependencies: mapsi: Depends: libqtm-11 but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). /home/user # Actually Mapsi without icon is installed, but when I click it, only black screen is shown.
