I'm trying to install the Git-Trac command by following the instructions given here. When I run the command
git clone https://github.com/sagemath/git-trac-command.git
I get the following error message: "fatal: unable to access 'https://github.com/sagemath/git-trac-command.git/': SSL certificate problem: Invalid certificate chain"
Any suggestions on how to deal with this?
