The travis job is killed at 2hrs, is it possible to ask travis to increase the build time limit?

Yes, but 2h is already an extension. Is there some tool where conda install takes ages? Some R deps? Github actions offer 5h build-time. But this also might time out if conda resolution is the problem.

Ok, I thought that 2h was the default.
I don't see a single install being much slower, it's just most of them that take some time
Maybe I'll try migrating to github actions. Anyway for now the tests would fail after the install step (bgruening/docker-galaxy#560)

So nice!

All green now, and tested locally, so time to merge :)
