This still fails for me: http://paste.ubuntu.com/p/vdN9dBxKBr/
.... Building bootmap in '/boot' Adding IPL section 'ubuntu' (default) Preparing boot device: vda (0000).

Note this is the new code, as in it's now asserting in hook.cc:184 which the new line where the assert has moved. I wonder if these things are racy or something. At the moment, this fails whilst trying to install the kernel, when running subiquity -> curtin on s390x. With ubuntu-advantage-tools 19.3 everywhere. ** Changed in: ubuntu-advantage-tools (Ubuntu) Status: Fix Released => Confirmed ** Changed in: ubuntu-advantage-tools (Ubuntu) Assignee: Andreas Hasenack (ahasenack) => (unassigned) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1824523 Title: Assertion error during iso build To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-advantage-tools/+bug/1824523/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
