Currently it’s important that we run UI tests on Python 3.5.4, so we use the
python-3.5.4-browsers image. Problem is, this doesn’t get rebuilt any more so its browser versions are very out-of-date (and doesn’t have the fixes to the
jessie repository issues experienced last month). Updating the browsers in a script is not ideal as introduces other failure points (like Chrome’s signing key becoming invalid last week), not to mention adding 30s or so on top of a build that should only take 1min.
Is there any way to get this particular build refreshed?
