release-26.3: roachtest: apt_problem failed

**Note:** This build has runtime assertions enabled. If the same failure was hit in a run without assertions enabled, there should be a similar failure without this message. If there isn't one, then this failure is likely due to an assertion violation or (assertion) timeout.

Jira issue: CRDB-64925

Start with the roachtest README, then inspect the artifacts under /artifacts/django/run_1 and the named run_164105.246996403_n1_sudo-aptget-qq-insta.log. Use the linked TeamCity output and the existing issue discussion to determine why dependency installation returns apt_problem; done means the django roachtest no longer fails for this cause.
