SoC EDS, compile uboot for Arria 10 SoC

Hi,

I have a  product with Arria 10 SoC, 10AS066H3F34I2SG.
I need to compile uboot.
I have a Linux Ubuntu 24.04.2 machine (x86 64-bit).
I previously used SoC EDS 19.1 on an older Linux machine.  I downloaded the Linux version for this and installed it.
As other discussions here have asked installing EDS appears to require dependencies such as
libc6:i386
libncurses5:i386
libstdc++6:i386
zlib1g:i386

Just installing EDS does not complete the DS-5 install (the ARM 32-bit libraries appear to be missing).  I assume the 32-bit ARM libraries are required to compile uboot.  Am I making correct assumptions on the required dependencies to compile uboot?

The i386 dependencies appear to no longer have valid fingerprint keys for Ubuntu 24.  How can I compile uboot?

Best regards,

Pete
