Problems with https in submodule integration

[berndbischl]

We apparently need this for travis ci.
Why again? I forgot.

This now causes this problem on LIDO:

bischl@lidong2:~/cos/coseal-algsel-benchmark-repo> git submodule update
Cloning into 'algselbench/makeR'...
fatal: unable to access 'https://github.com/tudo-r/makeR.git/': SSL certificate
problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
Clone of 'https://github.com/tudo-r/makeR.git' into submodule path
'algselbench/makeR' failed

Why again? I forgot.

You cannot checkout a repository via git@github.com:* w/o your public ssh keys being registered as project admin, i.e. write access to the repository.

Is there any alternative way?

I also have to yet check the workaround that was suggested yesterday for lido, ie via sshfs on another system. That's tedious, but you would only need to do this EXTREMELY rarely as we nearly never have to update makeR anymore.
