Eclipse authorization problems

We updated GitLab last night and updated the OS too - unfortunately at the same time. We were running on 7.11.4 and apt-get took us straight to version 9. Needless to say this has left CI unusable until I can figure out how to get that rolling again, but the larger issue this morning is that almost everyone has trouble doing fetches/pulls/pushes from Eclipse. Not being anyone special, I’m also affected. I’ve attached a screen shot of what I get when I attempt a fetch from one of my repositories. Anything I can try?

Thanks to a co-worker we found that GitLab 9 wants an RSA key and not DSA, what we previously had configured. At least I got the answer!
