Jira issue: CRDB-54308

Start with the roachtest README and the run_105535.368044081_n1-6_sh-c-sudo-DEBIANFRON.log artifact for jepsen/sets/subcritical-skews, then compare the related apt_problem issues on other branches. Done means the underlying apt_problem failure is understood and the roachtest passes without the transient apt error.
