release-26.3.1-rc: 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-66777

Start with the failure log run_101631.814610771_n1_sudo-aptget-qq-insta.log and the roachtest README, then inspect the apt_problem report and the django test entry point at django.go:70. Determine why dependency installation exits with status 100 and verify the apt_problem failure no longer reproduces on the affected release branch.
