hostkey doesn't work for github

[sebastiaandegeus]

I added a hostkey for github the automatic way: dokku hostkeys:shared:autoadd github.com

This adds the key and during deployment it says:

----> Installing Hostkeys in build environment ...
       No app keys available.
       Adding shared keys.
-----> Done Installing Hostkeys in build environment ...
       Added the following keys:
       |1|mYAxNC3vsEL66uhKGDgh9LwDoZQ=|V/D7XlZCX/voWV+FjbUo7nKAV+E= ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAq2A7hRGmdnm9tUDbO9IDSwBK6TbQa+PXYPCPy6rbTrTtw7PHkccKrpp0yVhp5HdEIcKr6pLlVDBfOLX9QUsyCOV0wzfjIJNlGEYsdlLJizHhbn2mUjvSAHQqZETYP81eFzLQNnPHt4EVVUh7VfDESU84KezmD5QlWpXLmvU31/yMf+Se8xhHTvKSCZIFImWwoG6mbUoWf9nzpIoaSjB+weqqUUmpaaasXVal72J+UX2B+2RPW3RcT0eOzQgqlJL3RKrTJvdsjE3JEAvGq3lGHSZXy28G3skua2SmVi/w4yCE6gbODqnTWlg7+wC604ydGXA8VJiS5ap43JXiUFFAaQ==

Which seems ok.

       Failed to execute git clone --no-checkout 'git@github.com:deliciousbrains/wp-amazon-s3-and-cloudfront.git' 'web/app/plugins/wp-amazon-s3-and-cloudfront/' && cd 'web/app/plugins/wp-amazon-s3-and-cloudfront/' && git remote add composer 'git@github.com:deliciousbrains/wp-amazon-s3-and-cloudfront.git' && git fetch composer

Weird thing is this works for another server. But on this one it keeps failing. I tried deploying without any composer git packages and then it works fine. So it's absolutely some error during cloning.

But still during deployment it throws the error:

       [RuntimeException]

One thing I've noticed is that - at least for the current version of dokku - the github.com domain seems to be resolved and then the git clone fails. Every so often I add a new hostkey, though thats a bit annoying :(

Maybe we can get hold of a list of popular hostkeys somehow? I could imagine a list of hosts for github and bitbucket maybe.
