I apologize: my case it's not OSP13, so it may not be relevant here. Still the error looks the same, so it may be something that changed in RHEL.
Update: I could reproduce the same issue on OSP13, and a reboot did not help. sahara-image-elements-8.0.1-2.el7ost.noarch diskimage-builder-2.16.0-2.el7ost.noarch dib-utils-0.0.11-1.el7ost.noarch
It will fail on every image build based on this RHEL 7.6 image, as there is currently a syntax error on their grub defaults: https://bugzilla.redhat.com/show_bug.cgi?id=1646976 > > GRUB_CMDLINE_LINUX="console=tty0 crashkernel=auto" console=ttyS0,115200n8 > > no_timer_check net.ifnames=0 > > > > As you can see, this syntax is wrong, as the quotes are not covering all the > > parameters. The exact syntax needs to be: > > > > GRUB_CMDLINE_LINUX="console=tty0 crashkernel=auto console=ttyS0,115200n8 > > no_timer_check net.ifnames=0"
I confirm that if I fix the content of /etc/default/grub on the image, sahara-image-create (aka diskimage-builder) works (on OSP13 and later). Should this bug be reassigned to the other product and closed as duplicate of rhbz#1646976 ?
Closing this out. https://bugzilla.redhat.com/show_bug.cgi?id=1643273 is the same issue and has also been closed. The RHEL 7.6 bug https://bugzilla.redhat.com/show_bug.cgi?id=1646976 is the issue here. *** This bug has been marked as a duplicate of bug 1646976 ***
