I have not figured out why it was hanging, but I have discovered that wrapping the call in debconf-apt-progress not only presents a proper progress bar, but also somehow avoids the hang.
So, my full late_command is: d-i preseed/late_command string in-target sh -c "debconf-apt-progress --logstderr -- aptitude -q --without-recommends -y -o DPkg::options =--force-confnew full-upgrade" (The options that I'm using are there because I copied them from the pkgsel code handling the pkgsel/upgrade step.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/605149 Title: Upgrade to cups-bsd_1.4.3-1ubuntu1.2 hangs during preseeded install -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
