Add GPG pub key to apt repo.
Remove GPG key, does not work.
Will fix it.
Add back Public Key.
Still does not work, I do not know why (same key as packages).
Update zsdx package.
I accidentally removed the source package.
I will put in a source package for 1.9 zsdx.
Recommit zsxd and solarus packages.
32-bit may work.
