Update SQLite in travis CI

Question

On python 3.6 and 3.7 (django 2.2) I am getting django.core.exceptions.ImproperlyConfigured: SQLite 3.8.3 or later is required (found 3.8.2). On TravisCI

What I Did

• I tried installing it with addons:

addons:
  apt:
    sources:
      - travis-ci/sqlite3
    packages:
      - sqlite3

The sources here got ignored

Disallowing sources: travis-ci/sqlite3
To add unlisted APT sources, follow instructions in https://docs.travis-ci.com/user/installing-dependencies#Installing-Packages-with-the-APT-Addon

• And with ppa in before_install

before_install:
  - sudo apt-add-repository -y ppa:travis-ci/sqlite3
  - sudo apt-get -y update
  - sudo apt-get -y install sqlite3=3.7.15.1-1~travis1

error:

Cannot add PPA: 'ppa:travis-ci/sqlite3'.
Please check that the PPA name or format is correct.

How can I get it to work?

Update your build enironment to Xenial. Trusty contains only SQLite 3.8.2.

dist: xenial
language: python
