Using strace and friends is a bit too low level to debug execution of bash scripts =)
You can try: $ sudo bash -x update-initramfs -u -v And attaching log of that. And you can use also add "set -x" in the hooks that are called (and/or are hung); and attaching a log of that to see where/when it is hung. Rebooting should be safe, as you should have ubuntu old working boot loader entry. To be on the safe side you may want to execute $ sudo zipl, right now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1662187 Title: apt-get upgrade hung when it comes to update initramfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1662187/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
