Running Debian testing/sid (stretch), spotify-client from Spotify's testing repository no longer works.
spotify: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory
Looks like a recurring theme, as we have just recently survived the libssl0.9.8 to 1.0.0 transition, but we're going to have to enjoy 1.0.2. I doubt Debian will be easily persuated to stop upgrading their security related libraries so that we can run our favorite non-free software. Someone else will have to be flexible here :)
