Oh! I just spotted the problem here. When running in d-i, debootstrap uses base-installer/pkgdetails.c to provide progress output. That looks for anything vaguely like a percentage, which matches the URL-encoded colon ("%3a").
I still have some work to do for this, but it has my attention now that I've figured out that particularly inscrutable failure. ** Also affects: base-installer (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1172101 Title: wget-udeb should install to /usr/bin/wget instead of /usr/bin/wget.gnu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/base-installer/+bug/1172101/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
