No changes made in the config, but it’s a couple of weeks that the jruby 1.7 and 9.0 builds fail with an installation error.
Example of failed build [here](https://travis-ci.org/ddnexus/pagy/jobs/571225796)

Probably a side effect of the default changing from Trusty to Xenial.

It’s not entirely clear to me how you would make this work on Xenial, but you could try choosing different versions of JDK, and/or pinning to older versions of JRuby.
