As a final sanity check, I built a new debian-installer monolithic netinstall ISO image, along with the usual vmlinuz / initrd.gz files. When I built them, I enabled -proposed, and debootstrap-udeb 1.0.95ubuntu0.7 was included in the generated MANIFEST.udeb file.
The ISO images and initrd.gz files are here: https://people.canonical.com/~mruffell/sf289200-proposed/ I did a test install with the mini.iso image, selecting [Advanced Install] then [Command Line Expert Install]. When it asked for package mirrors, I selected https, and used a local mirror that supports https, mirror.fsmg.org.nz. The install worked as expected with no errors. I checked /etc/apt/sources.list in the installed system, and all the apt sources pointed to deb https://mirror.fsmg.org.nz/ubuntu/ bionic main The package in -proposed fixes the problem, and works with https mirrors. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772556 Title: d-i netinstall fails due to missing apt-transport-https package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debootstrap/+bug/1772556/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
