Problem

Tried to install LuaSec on a new machine recently and got the following error:

luarocks install luasec
Warning: Failed searching manifest: Failed loading manifest: Failed fetching manifest for http://luarocks.org/repositories/rocks - Error fetching file: Failed downloading http://luarocks.org/repositories/rocks/manifest - URL redirected to unsupported protocol - install luasec to get HTTPS support.

So all I need to do to install LuaSec is install LuaSec first,  brilliant!

Solution

One solution is buried here https://github.com/luarocks/luarocks-site/issues/6

and is to specify the server directly:

luarocks install --only-server=http://rocks.moonscript.org luasec
