Install Google Play Music Plugin for Rythmbox on Ubuntu 12.04

Question

I've tried to install Google Play Music Plugin for Rythmbox. I've first tried to install it via PPA as described here.

After executing

sudo apt-get install rhythmbox-gmusic

I get an error message wich says (might not be the correct output in english since I hadd to translate it from german, but I think everyone knows whats happening)

packagelists are read... done
dependencytree gets build
statusinformation are read... done
some packages could not be installed[...]
the following information might help you, to solve your problem:

the following packages have unmet dependencies
 rhythmbox-gmusic : depends on: python-validictory but is not installable
E: problems can not be corrected, you have hold back damaged packages

So after this I've tried installing the plugin via via PIP as described here

This succeeded but I've try to enable the plugin I get a warning sign (red sign with wide horizontal line) like described in this Question

Note: I've tried all 3 solutions given in this thread

But if I try installing python-validictory with

sudo apt-get install python-validictory

I get following output (again translated from german)

packagelists are read... done
dependencytree gets build
statusinformation are read... done
package python-validictory is not available, but is referenced in another package.
This can mean that the package is missing, that it got redeemed or is only available from another source.

E: package »python-validictory« has no installation candidate

Can someone please tell me how I can get python-validictory or how I get this plugin to work. Thank you in advance.

[Update] I forgot to mention that I also looked at this site but don't know what

These packages can all be installed fron universe/main.

means.

Solution

These packages can all be installed from universe.

You have to enable universe repository.So that the python-validictory package would be installed.

sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"        # command to enable Universe repository

sudo apt-get update                                                                               # Command to update all repositories
sudo apt-get install python-validictory                                                           # Command to install python-validictory package

Edit

sudo add-apt-repository ppa:dput-ng-maint/daily
sudo apt-get update
sudo apt-get install python-validictory

Edit

After those commands run

sudo -i
curl https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py | python
exit
sudo apt-get install python-pip
sudo pip install gmusicapi --upgrade

Now open your Rythmbox and enable the Google Play Music plugin.

I've tried your solution it seems that this repository was already enabled and it still couldn't install python-validictory. I still get the same error message

Now try my edit.

after I tried your edit, I was able to install python-validictory. But still couldn't enable the Google Play Music plugin. So I tried any solution from the above mentioned Question and for some reason when I executed sudo pip install gmusicapi --upgrade I got an error message telling me ImportError: no module named pkg_resources But could solve this problem by using this answer Note: I had to execute the command in this answer with sudo -i to make it work

[Jamie-505]

so after those steps I executed sudo apt-get install python-pip and sudo pip install gmusicapi --upgrade which finally did the trick
