So, for sure python-qtmobility is available on the N9 repo mirror. Looks like some other dependency is the problem. Maybe we derail this thread, maybe not. What you can/should do is install everything manually: devel-su apt-get install modrana - error thrown about python-qtmobility, then apt-cache search python-qtmobility -see that it is available, and continue with apt-get install python-qtmobility read the log, find out which package is problem and continue with last two steps (apt-cache search ... and apt-get install ...) Maybe this way we can narrow it down to the real problem.
