Read the roachtest README and inspect django.go at line 70, then review the linked TeamCity artifacts, especially run_071339.247098402_n1_sudo-aptget-qq-insta.log under /artifacts/django/run_1. Determine why dependency installation repeatedly returns apt_problem and verify the apt_problem test completes successfully.
