How do I restore APT defaults?
Download the file, back up the current one in /etc/apt/sources.list, replace it, then reload or restart APT.
Is sources.list safe for production?
It is the vendor default for Ubuntu 18.04 LTS (Bionic Beaver). Treat it as a baseline and review security and performance settings before production use.
How does this differ from other OS versions?
Defaults vary by distro and version. This copy matches Ubuntu 18.04 LTS (Bionic Beaver).
Can I use this for APT troubleshooting?
Yes. Diff it against yours to find drift, then restore only the sections you need.
