There might be a small issue with installing FixedMathSharp in Unity 6.5. For me, installing with Git causes the package manager to get stuck on "Installing a new package".
It looks like the cause might be that in the package manifest, the path for the sample points to a specific scene, whereas Unity is expecting it to point to a folder. However, for me at least there's no indication of this when trying to install from Git, so it may not be obvious to users why installation appears to be getting hung up.
If you're interested, you can find further info and discussion in this Unity forum thread.
