Hi Seeteena,

Yes the Ubuntu builds are the latest ones available in bionic site as per the date:
We get daily images here:
http://ports.ubuntu.com/dists/bionic/main/installer-ppc64el/current/images/netboot/

Also, the netboot.tar.gz is dated 2018-02-08 even today!

netboot images are not updated after Feb 8,2018.

The images at http://ports.ubuntu.com/dists/bionic/main/installer-ppc64el/current/images/netboot/ are updated to a version from today (22 Feb), which should resolve this issue.

Note that the images are only updated whenever the debian-installer package changes. In principle, that should happen each time the linux package is updated in the release pocket. Looking at the history, it is unclear to me why things were out of sync for you; however, as all of these packages have revved since then, the original issue should be resolved. Please reopen if you find that it recurs.

but unlike before, the installation could proceed without loading kernel modules completed and system came up with ubuntu18.04
