Like most of my posts here, this is mostly a note to myself so I don't forget how I did it.

I Moved to Debian 9 on my desktop box at home and everything works great except I occasionally use Mega.nz and they don't provide a Debian 9 build. It would be great if they just provided a statically linked generic Linux binary, but they don't. So, to make it work, grab their Debian 8 .deb file.
