That error message comes from debootstrap, not from lxc-create. lxc-create in your case calls the lxc-debian script which in turn calls debootstrap. On failure, lxc-debian cleans up the build environment which is why the log file disappears.
Anyway, the actual error is perfectly visible on screen, the error is that /proc can't be mounted which is usually a sign of you attempting to run lxc-create inside a container without having properly enabled nesting for that container. ** Changed in: lxc (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1671990 Title: failing lxc-create doesn't create log file mentioned in error message To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1671990/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
