# Upstream catmaid/catmaid-standalone bakes the PostgreSQL Global
# Development Group (PGDG) apt repo, but PGDG retired focal-pgdg when
# Ubuntu 20.04 hit standard EOL — its Release file is gone, so apt-get
# update aborts. Postgres is already installed in the base image, so we
# strip any apt source line referencing PGDG (filename varies across
# upstream builds — pgdg.list, pgdg-postgresql.list, etc.) before running
# update.
#
# focal is past standard support; we apply what patches still flow into
# focal-updates/focal-security with apt-get upgrade. ESM-only CVEs (e.g.
# many libssl, openssh, glibc fixes after April 2025) require an Ubuntu
# Pro token which we don't ship; the longer-term fix is to rebase
# catmaid-standalone on jammy or noble.
