I have a custom boart based on T4241. Using LSDK 18.06 i was able to build u-boot, kernel, dtb, buildroot ramdiskfs and to bring the board up with ramdisk. There is ssd on my board, and I would like to install ubuntu rootfs there, but failed to build it:
root@fbubuntu:~# flex-builder -i mkrfs -a ppc64
/home/g10/peshkin/flexbuild/build/rfs/rootfs_ubuntu_bionic_ppc64 exist but imcomplete, regenerate it ...

E: Invalid Release file, no entry for main/binary-ppc64/Packages
Please suggest the way to obtain complete Ubuntu rootfs.
