Update rpmbuild version in Travis CI build using apt

Hi team,

I want to use rpmbuild >= 4.13 which can be installed via apt-get install rpm on linux. I tried to update and then install using apt. But it says 4.11 is the latest version. Can someone tell me how I can update the rpmbuild to latest version?

Travis ci build: https://travis-ci.org/leopardslab/dunner/jobs/538587412#L644
Travis config: https://github.com/leopardslab/dunner/blob/deb-package/.travis.yml

Thanks

I you upgrade to dist: xenial, you’ll get rpm 4.12.0.1.

Newer versions are not available out of the box since Travis doesn’t support Bionic.
