Installing Google Music Manager on Fedora 21
If you're wondering why Google Music Manager isn't starting after you installed it from their website, here's the problem:
$ google-musicmanager /usr/bin/google-musicmanager: error while loading shared libraries: libQtWebKit.so.4: cannot open shared object file: No such file or directory
How to resolve it,
yum provides '*/libQtWebKit.so.4'
Repo : fedora Matched from: Filename : /usr/lib/libQtWebKit.so.4 Filename : /usr/lib/sse2/libQtWebKit.so.4 qtwebkit-2.3.4-1.fc21.x86_64 : Qt WebKit bindings Repo : fedora Matched from: Filename : /usr/lib64/libQtWebKit.so.4 qtwebkit-2.3.4-1.fc21.i686 : Qt WebKit bindings Repo : @fedora Matched from: Filename : /usr/lib/libQtWebKit.so.4 Filename : /usr/lib/sse2/libQtWebKit.so.4
sudo yum install qtwebkit qtwebkit-devel
Now it should load for you :) Would be damn helpful if Google just included it as a dependency with the rpm..
However once it's loaded, the problems aren't gone yet. There seems to be ANOTHER bug, with actually getting it to load, the current workaround seems to be, empty your Music directory first (or choose an EMPTY directory) to first upload your files. Don't worry if it says it failed to upload or there are less than 10 songs in the directory. Follow through and then reopen it again, and finally it'll load what we wanted to see.
If you don't follow these steps, you'll find you can't open it again..
Finally, if it goes missing again, check your message icon tray as it's probably just minimized itself. Windows Key + M, and you'll see that tiny headphone icon tucked away in the bottom right corner.
Enjoy the music
