Thanks for your bug report. I am reassigning this to the installer, but it seems more likely that this is a result of user error, given that there have not been any relevant changes in focal's installer. For user support, please use askubuntu, discourse, the ubuntu-user mailing lists, or the #ubuntu IRC channel on Libera.
If you believe this to be an installer bug, to collect additional data for the bug report, run `apport-collect 1965121` in a terminal and follow the instructions. This will provide us the installer log. Also please attach the incomplete sources.list that was supposedly generated by the installer. ** Package changed: apt (Ubuntu) => ubiquity (Ubuntu) ** Changed in: ubiquity (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1965121 Title: "archive.ubuntu.com" was missing in "/etc/apt/sources.list" Status in ubiquity package in Ubuntu: Incomplete Bug description: Right after clean install, "archive.ubuntu.com" was missing in "/etc/apt/sources.list" as summary.
