Maintenance Tool problems
to somebody competent: Maintenance Tool has some problems on my Kubuntu 12.04, 64-bit:

Repeated fails to download a component:
This happens to me both at home and at work, so it's not a problem of my internet connection.
You are probably getting connected to a bad download mirror. See https://github.com/JKSH/QtSdkRepoChooser on how to choose a different mirror.
