# Switch apt sources to Hetzner's public mirror.
# Ubicloud runners (Hetzner FSN1-DC21) hit reliable connection timeouts to
# archive.ubuntu.com:80 — observed 90+ second outages on multiple builds.
# Hetzner's mirror is publicly accessible from any cloud and route-local for
# Ubicloud, so this fixes both reliability and latency. Ubuntu 24.04 uses
# the deb822 sources format at /etc/apt/sources.list.d/ubuntu.sources.
#
# Using HTTP (not HTTPS) intentionally: the base ubuntu:24.04 image ships
# without ca-certificates, so HTTPS apt fails with "No system certificates
# available." Apt's security model verifies via GPG-signed Release files,
# not TLS, so HTTP here is no weaker than the upstream defaults.

# Node.js 22 LTS (needed for claude CLI).
# Install from the official nodejs.org tarball instead of NodeSource's apt setup.
# NodeSource's setup_22.x script runs its own `apt-get update` + `apt-get install gnupg`,
# both of which depend on archive.ubuntu.com / security.ubuntu.com being reachable.
# Ubicloud CI runners frequently can't reach those mirrors (connection timeouts),
# and "gnupg" was renamed to "gpg" on Ubuntu 24.04 anyway, so NodeSource's script
# fails before it can add its own repo. Direct tarball download is network-simpler
# (one host: nodejs.org) and doesn't touch apt at all.
