I can now reproduce the failure by running the test with nosetests3 manually.
Removing the "--log-path=/tmp/chromedriver.log" service arg fixes the issue. The confined chromedriver bails out when it fails to write there: $ /snap/bin/chromium.chromedriver --log-path=/tmp/chromedriver.log Starting ChromeDriver 75.0.3770.90 (a6dcaf7e3ec6f70a194cc25e8149475c6590e025-refs/branch-heads/3770@{#1003}) on port 9515 Only local connections are allowed. Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code. Failed to redirect stderr to log file. Unable to initialize logging. Exiting... Given that the log file isn't exposed as a retrievable artefact when autopkgtests are run, I suggest we just remove it. If it turns out that a significant number of existing selenium tests do the same, we could consider patching chromedriver in the snap to ignore that argument, instead of bailing out. ** Changed in: chromium-browser (Ubuntu) Status: New => Confirmed ** Changed in: chromium-browser (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834052 Title: autopkgtest failures: Chromium-Related in Tests To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1834052/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
