Bug 13499

Following two steps are executed:
repo init -u https://github.com/Angstrom-distribution/angstrom-manifest -b angstrom-v2018.12-thud
repo sync
Also tried:
sudo sysctl -w net.ipv4.tcp_window_scaling=0
repo --trace sync -j1

Below link is no longer available:
http://git.yoctoproject.org/git/meta-freescale
Where do i update in the setup to correctly build the yocto setup?

Getting below Error message:
