Hi! I tried to check out iron ruby sources following the instructions in [IronRuby.net / Get IronRuby](http://www.ironruby.net/Download) but bumped into problems: nak@NW32 /cygdrive/c/programs/dotnet/ironruby $ git clone git://github.com/ironruby/ironruby.git Initialized empty Git repository in /cygdrive/c/programs/dotnet/ironruby/ironruby/.git/ remote: Counting objects: 23971, done. remote: Compressing objects: 100% (14767/14767), done. remote: Total 23971 (delta 7698), reused 23764 (delta 7544) Receiving objects: 100% (23971/23971), 33.40 MiB | 242 KiB/s, done.

No idea. Can you clone any other GIT repo? Did you Google for it? Btw, I found that the GIT tutorial at [gittutorial(7)](http://www.kernel.org/pub/software/scm/git/docs/gittutorial.html) is very helpful for ramping up on GIT concepts. Thanks, Shri ---

No, iron ruby is my first contact with git. Now that you mentioned it I tried to clone a random project from github and it gives the same error, so the problem is probably with my git installation. > Did you Google for it? Yes, but didn’t find anything that would solve the problem. There were some reports of the same problem on different projects, but no solution. > Btw, I found that the GIT tutorial at > [gittutorial(7)](http://www.kernel.org/pub/software/scm/git/docs/gittutorial.html) is very > helpful for ramping up on GIT concepts. Thanks. I’ll take a look once I get the basic cloning working… ``` ::Antti:: ``` ---

If the cygwin installation keeps messing up, try the Msysgit one at [Google Code Archive - Long-term storage for Google Code Project Hosting.](http://code.google.com/p/msysgit). If you select the second option when it asks you where to run Git from, you can use it from CMD. JD ---

I actually already tried it, but it gives the same error. 😕 There is something very strange about this: two different versions of git (cygwin and mingw) both fail on all the git projects I tried to clone (iron ruby, jruby and some random one I picked from github). This seems to indicate there is something wrong with my environment, but I can’t think what it could be - I’m running a quite regular win xp sp 2. I also tried disabling windows defender and symantec firewall (as I found someone suggesting this in a similar issue I found when googling) but that made no difference. ``` ::Antti:: ```
