I can't reproduce this issue here; trying to install ubuntu-server and preseeding apt- setup/local0/repository="http://ppa.launchpad.net/cyphermox/ppa/ubuntu zesty main".
The preseeded repository is indeed showing in sources.list and is written correctly. If you can still reproduce this bug, please include both the exact preseed used, along with the full contents of /etc/apt/sources.list at the end of the install so we can see what happens. ** No longer affects: console-setup ** Changed in: console-setup (Ubuntu) Status: Confirmed => Invalid ** Package changed: debian-installer (Ubuntu) => apt-setup (Ubuntu) ** Changed in: apt-setup (Ubuntu) Importance: Critical => High ** Changed in: apt-setup (Ubuntu) Status: Confirmed => Incomplete ** Changed in: console-setup (Ubuntu) Importance: Critical => Undecided ** Changed in: hundredpapercuts Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to console-setup in Ubuntu. https://bugs.launchpad.net/bugs/1584685 Title: Xenial fails to install with Preseed d-i apt-setup/local0/repository set Status in One Hundred Papercuts: Incomplete Status in apt-setup package in Ubuntu: Incomplete Status in console-setup package in Ubuntu: Invalid Bug description: Preseed install of Ubuntu Xenial fails with d-i apt- setup/localX/repository option set. The problem is that debian installer does not concat the last string in sources.list correctly. The prefix "deb" is missing. So apt fails to update and the installer cannot continue because there are no valid package sources.
