fix spotify error (libgcrypt)
Fix Spotify not launching issue:
Ubuntu 15.04 misses the libgcrypt11 package in its official repositories, so that Spotify won’t launch and you’ll get below error message if you start it from terminal:
spotify: error while loading shared libraries: libgcrypt.so.11: cannot open shared object file: No such file or directory
To fix the issue, just download and install the package from the repository of Ubuntu 14.04 LTS.
libgcrypt11 for 64-bit OS
libgcrypt11 for 32-bit OS
Don’t know your OS type? Check it out at top-right corner shutdown menu -> About This Computer.
Once downloaded, click the package to open with Ubuntu Software Center and install it. Finally launch Spotify client from the Dash/App Menu.
