User:Closeapple/new/Wikipedia:FTCG on Mono

This is a document about using For The Common Good with Mono, which should allow FTCG to work on Linux and other non-Microsoft operating systems.

Using with Mono

Mono is a non-Microsoft implementation of .NET Framework. Non-Microsoft operating systems, such as Linux and MacOS, should be able to run For The Common Good using Mono.

1. Install Mono on your system.
   • For Debian and Ubuntu distributions: Install the mono-runtime and mono-devel packages with whatever package manager you wish. (You need mono-devel temporarily only because you need the certmgr program to get Wikimedia's SSL certificates because FTCG uses HTTPS to communicate instead of HTTP.) If you don't have a package manager preference, go to the command line and do this:
     1. sudo aptitude -u
     2. sudo aptitude install mono-runtime mono-devel
     3. When you are asked if you want to install some large number of packages (probably 190) or so, type y and hit Enter.
   • Mono's download page has download information for other platforms.
2. Run certmgr to get the SSL certificates for Wikipedia:
   1. certmgr -ssl https://en.wikipedia.org/
   2. certmgr -ssl https://commons.wikimedia.org/
   • You might be asked Import this certificate into the Trust store ? — type y and press Enter each time you are asked.
   • If certmgr dont work you can use mozroots to import certificates.
3. Run FTCG. From the command line, it's as easy as running the command "mono" with the location of the FTCG executable file:
   • mono ForTheCommonGood_1.0.4.exe

Problems

When I hit Go on a Wikipedia file, I get an error dialog that says "An Internet request failed. Error getting response stream (Write: The authentication or decryption has failed.): SendFailure".

You didn't import the SSL certificates for Wikimedia sites into Mono yet. See the certmgr part of the instructions above.

When I hit Go on a Wikipedia file, FTCG crashes and exits. The diagnostic messages in the terminal window begin with Unhandled Exception: System.Net.ProtocolViolationException: The number of bytes to be written is greater than the specified ContentLength. I've already installed the certificiates.

Here's where we have a problem!
