# `apt-get update` can exit non-zero when an unrelated third-party
# repo baked into the runner image (e.g. dl.google.com/chrome) serves
# a stale index (Hash Sum mismatch). That must not fail our build —
# the Ubuntu archive lists still refresh, so tmux installs cleanly.
# `tmux -V` then asserts tmux is actually present, so a genuine
# install failure still fails the job loudly.
