Default on Travis is Ubuntu 16.04 (Xenial). Given the somewhat flaky support of rgdal for GDAL<3 & PROJ <6 (see ), an easy fix is to upgrade GDAL & PROJ. They are at version 3 and 6 on the Ubuntu Focal repositories, so that should suffice. If upgrading to 20.04 works for r-language on travis!!
It seemed Focal was not supported; automatically uses Xenial. Let's try bionic!
This is a more logical way of adding PPA and deb packages. It is done before cloning the github repo and before loading the build cache. Its effect can be seen in https://travis-ci.com/github/inbo/inborutils/jobs/396969884#L789-L808. This was done with help of Jeroen Ooms, see travis-ci/travis-build#1962.
It seems this package was already included in the Travis image. I drew wrong conclusion from it being missing in my local Focal installation.

This builds further on #89 (comment). Roughly the following steps were made:
rgdal,spandsfuse GDAL 3 and PROJ >= 6. If r.rb: use ubuntugis-unstable PPA travis-ci/travis-build#1962 would be accepted, then the 'unstable' PPA would become the default (hence not needed anymore in the yml file here).libfribidi-dev, necessary to compile the package dependencytextshapingofpkgdown
