Okay good then.  I am closing the ticket. Thanks!

Oh, sorry, should have been more clear: yes, it worked ever since I re-uploaded the last key.

At least one of the other keys is in use as well, but I'd have to check all my machines to figure out if it is the only one. Only ever had trouble connecting from the newly installed Ubuntu 16.04 (with the .ssh directory copied over from the working 14.04 no less), so I'll better keep everything as it is :-).

Is this still a problem for you? When I look at your stored ssh keys it looks like they still have problematic spaces in them.

I knew it was something stupid on my side! :-)

Thanks for figuring this out so quickly, Bob!

Hello Kai, Your uploaded key has spaces in them. Please double check that your paste is a clean paste of your ssh key. I think the presentation may have wrapped the key and this has crept into the paste. Double check the last two keys which both have spaces in them.  Let us know if that fixes things or not.

And there's a second issue I recently ran into. I've recently installed Ubuntu 16.04 and copied over my old .ssh/ configuration, with which I am able to access cvs just fine.

Doesn't work on the fresh install of 16.04, however. I tried creating a new key, but even a few days after uploading still no luck. Here's the relevant info

Pretty sure it's something stupid on my end, but cannot figure out what's wrong, and switching back and forth between OSes just to commit or check out some changes is getting inconvenient. So any help with that would be greatly appreciated. Thanks!
