I’m trying to add a collaborator to my project; They’re an MCECS student, but they don’t show up in the list. What’s going on?

Usernames don’t show up in the list until the user has tried to log into the projects web site at least once. If you’re not finding another student’s username in the list, ask them to log into Once they’ve done so, you will be able to add them successfully.

I can’t clone my git project through HTTPS – I keep getting a certificate error. What should I do?

Using git over HTTPS with your projects.cecs repository from a personal Linux computer

If you use HTTPS to access your git repository on, you may get an SSL verification error, which will look something like this:

error: SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed while accessing

If you get this error, you will need to install our Certification Authority certificate. Open a Terminal window (use Ctrl-Alt-T on Ubuntu systems), and follow these steps:

  • First, download the certificate file.  The file is found at “” and should be downloaded to “/usr/local/share/ca-certificates/projects.crt”:

    sudo curl -o /usr/local/share/ca-certificates/projects.crt

  • Second, update the computer’s certificate file to recognize the certificate we just downloaded:

    sudo update-ca-certificates

Alternate (insecure) method

If you simply cannot get the certificate process above to work, you may also configure git to ignore certificates completely. Note that this is not secure; use this method at your own risk!

If you decide to ignore certificates, add the following two lines to your ~/.gitconfig file:

ssl_verify = false
