I thought it would be perfect to have the “Minion” NAS always watching the shared Music folder to keep my music up to date. The following instructions assume you have a current Debian 8 “Jessie” and the LXDE desktop environment, although the latter condition may not be required to find this post useful.
First, download the Google Play Music Manager from here,selecting the appropriate architecture.
Then install dependencies
sudo apt-get install libqt4-opengl libqt4-xmlpatterns libqt4-network libqtwebkit4
Finally, dpkg the downloaded .deb (syntax assumes x64, .deb file in ~/Downloads)
sudo dpkg -i ~/Downloads/google-musicmanager-beta_current_amd64.deb
When I launched Google Music Manager from the LXDE “start menu” it only launched a player, which didn’t give me any options for sync. I had to manually open the application to get to the dialog to select folders. There was a few ways of doing this I found as I am still learning Linux, maybe someone can weigh in on a better solution. By GUI you can launch the Google Music Manager in /usr/share/applications or /opt/google/musicmanager/ (which the former points to). I also found a CLI way to launch it:
The last thing is to make sure that you start with choosing upload, rather than download as that will break the options menu for some reason. I can confirm. Here is a blog post about it where I found the solution. Thats it! As always, please post here any criticisms, workarounds, observations and complaints! I would rather be corrected than have incomplete information.
