Jira issue: CRDB-54876

Start with the run_133958.963651622_n1_sudo-aptget-qq-insta.log artifact under /artifacts/sqlalchemy/cpu_arch=fips, then read pkg/cmd/roachtest/README.md and the sqlalchemy test entry point referenced at sqlalchemy.go:69. Done means identifying why dependency installation returns apt_problem and making the roachtest pass reliably across the listed branches or documenting the confirmed infrastructure cause.
