Travis Focal ubuntu image uses now expired mongodb 4.4 package

Hi @mattihelminen,

Try this as a fix:

dist: focal
language: minimal

before_install:
  - wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
  - echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
  - sudo apt-get update
  - sudo apt-get install -y mongodb-org

services:
  - mongodb

The rest of your .travis.yml here.

Let me know if this works, I’ll look into this internally and see if we can have it fetch the right version.
