GSRDCompilingLinux fails

Hi.
I attempted to build linux on Ubuntu 18.04 according to Compiling Linux | Documentation | RocketBoards.org
At bitbake console-image-minimal
it failed with

“ERROR: Layer meta-altera-refdes is not compatible with the core layer which only supports these series: warrior (layer is compatible with zeus)”

Does anyonw know how to build that angstrom-build? Any fixes? Meanwhile it seems that there is no working procedure.
Thanks.
Ilya

Try this Building Yocto Rootfs ERROR

ERROR: Layer meta-altera-refdes is not compatible with the core layer which only supports these series: warrior (layer is compatible with zeus)

This error means that the meta-altera-refdes layer supports only zeus release which will not work when building the older warrior release distribution.

Try switching the meta-altera-refdes to an earlier branch of the github repository.
