I just did an update to https://wl.widelands.org/wiki/Download/ wiki page regarding a topic coming up probably very soon in the wild: TroubleshootingIf you have problems getting the sources, failing with a message like "Unable to negotiate with <IP>: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1": This is probably because you are using a new version of OpenSSH (>= 7.0), which has it disabled as default because of security reasons. You can add the following lines into your /etc/ssh/ssh_config or ~/.ssh/config file (on Linux at least, don't know about Windows or MacOS): This enables the old encryption method for the very specific host where Launchpad hosts its sources, while not allowing it for other hosts, thus not compromising your overall security too much. Hopefully, those guys at Launchpad are fixing the encryption soon. Edited: 2015-11-07, 13:25

I ran into this for month...
It seems that the launchpad developers couldn't fix this soon, because several third-party apps are involved: https://bugs.launchpad.net/launchpad/+bug/1445619/ So thanks for the wikiedit Edit: Link to whole bug instead of one comment Edited: 2015-11-07, 13:36

Thanks for clarification I've not tested it yet but your suggestion would prevent uploading code to widelands-dev or to my user branches, wouldn't it? What about: ? Fight simulator for Widelands:
