Research direction

Start with the failed run log run_084337.227091578_n1-6_sh-c-sudo-DEBIANFRON.log and the artifacts under /artifacts/jepsen/bank/majority-ring-start-kill-2/cpu_arch=arm64/run_1. Read the roachtest README and compare the related apt_problem issues on other branches. Done means identifying the recurring cause and addressing the failure so the affected roachtest configuration no longer reports apt_problem.
