This explains why it is not available anymore, but still its 1.08 version can be installed from deb, only it plays nothing.
The idea is that the player is orphaned since 2011 without an adopter and depends on gstreamer 0.10, which is scheduled for removal. If installed from deb, it is unable to play any type of file.
Looking for gstreamer 0.10 I have found and installed gstreamer0.10-nice
, to no effect.
Its future seems grim, but I want to use it as long as I can, because I like the way its file manager can access and manipulate different music directories.
~ In Manjaro it can be easily installed and works great.
