GPG errors with ubuntugis

Languages R

I am trying to set up an environment that contains ubuntugis and I get a GPG Error for two repositories: ‘http://dl.google.com/linux/chrome/deb stable InRelease’ and ‘https://packagecloud.io/github/git-lfs/ubuntu trusty InRelease’.

The .travis.yml looks as follows

# R for travis: see documentation at https://docs.travis-ci.com/user/languages/r

language: R
sudo: required
cache: packages
warnings_are_errors: true
dist: trusty
r:
  - release
  - devel

before_install:
  - sudo add-apt-repository ppa:ubuntugis/ppa --yes
  - sudo apt-get --yes --force-yes update -qq
  - sudo apt-get install --yes libudunits2-dev libproj-dev libgeos-dev libgdal-dev
  - Rscript -e 'install.packages("rgdal", repos="https://r-forge.r-project.org/")'

after_success:
  - Rscript -e 'covr::codecov()'

and the exact error messsage is the following:

$ sudo add-apt-repository ppa:ubuntugis/ppa --yes
$ sudo apt-get --yes --force-yes update -qq

Does this require adding the keys to the docker image? @jeroen, @jimhester

You need to remove dist: trusty from your .travis.yml file. This is an old version of Ubuntu that is EOL and no longer supported by PPAs.
