Cydia updating sources stuck

If you are on Windows, you may have to install a device driver to talk to your Android device over USB.
If your device is not detected, use Impactor's USB Driver Scan feature to attempt to automatically construct and install a driver for your device.

(This feature is currently not available in the Linux versions.) If you are having problems using Cydia Impactor (it crashes, doesn't work on your device, or simply doesn't make any sense) please join #android on irc.(for Android questions) or #iphone on irc.(for i Phone/i Pad/i Pod questions).
Cydia Impactor is a GUI tool for working with mobile devices.
It has features already, but is still very much a work-in-progress. You can use this tool to install IPA files on i OS and APK files on Android.
If you have already downloaded these packages, you must reinstall the Helper app manually.
This section will walk you through the upgrade process.
Step 4 Once the installation is over, restart the Springboard by tapping Respring.
