Fix CI trouble during apt-get install chromium-browser
It is often impossible to install all dependencies required by command
apt-get install chromium-browser.
The browser is used headless during acceptance tests to check we can get html as expected.
It looks possible to install the browser without
apt : https://github.com/scheib/chromium-latest-linux/blob/master/update.sh
And to run it in this way : https://github.com/scheib/chromium-latest-linux/blob/master/run.sh
An other way could be to use
firefox --headless from https://download.mozilla.org/?product=firefox-esr-latest&os=linux64&lang=fr
