Unity 5.1.0f3, Ubuntu 16.10, libgpg-error.so.0

Error message:

/opt/Unity/Editor/Data/Tools/libgpg-error.so.0: no version information available (required by /lib/x86_64-linux-gnu/libgcrypt.so.20)

The fix (for me at least):

sudo rm /opt/Unity/Editor/Data/Tools/libgpg-error.so.0
sudo ln -s /lib/x86_64-linux-gnu/libgpg-error.so.0 /opt/Unity/Editor/Data/Tools/libgpg-error.so.0
