Build errored when updating publication list

Hi there, Our project website is hosted on Github (
Recently I have been trying to update the publication lists and I keep getting errors during the build. Here is the most recent one: Travis CI - Test and Deploy with Confidence

Any ideas what could be causing this?

Hi @johannag126,

Out of curiosity can you try defining focal in your .travis.yml. See if that solves the problem.

Remember, when Travis restores the cache, sometimes you’re left with a mix of preinstalled and cached files, with unpredictable results in a case of the slightest change.

Thanks @Montana, appreciate the help ! I was not 100% how to define focal in .travis.yml
Based on documentation I found, I added the line “dist: focal” in .travis.yml. I still got a build error unfortunately: Travis CI - Test and Deploy with Confidence
Please let me know if I should have done anything different or if I should try something else entirely…

Hi there, just checking again if anyone has any ideas on what to try to fix this bug. Thanks!

Hi @johannag126,

I’ve switched your dist to xenial here’s a .travis.yml you should try and get back to me:

# Doctr requires python >=3.5
language: python
  - 3.6

# * gh-pages need to be deployed to master
# sphinx source lives in "source" branch

# safelist
  # don't build the docs on master because that's just the html source
  - master

# This gives Doctr the key we've generated
sudo: false
    # Doctr deploy key for ocean-eddy-cpt/
