Use Linode mirror for apt to avoid archive.ubuntu.com outages

2b3b38cd by Isaac Bythewood · 25 days ago

Use Linode mirror for apt to avoid archive.ubuntu.com outages archive.ubuntu.com and security.ubuntu.com have been intermittently slow or unavailable, causing build-time apt-get install steps to fail with exit 100 mid-download. Linode runs an officially-documented mirror in every datacenter, on the same network as the host with free traffic. Rewrite both endpoints in /etc/apt/sources.list.d/ubuntu.sources before the install step.
