ovmf build fails on Ubuntu 20.04

Hi,

when running the command

nice build -v --cmd-len=64436 -DDEBUG_ON_SERIAL_PORT=TRUE -n 32 -t GCC5 -a X64 -p OvmfPkg/OvmfPkgX64.dsc

I get the following error:

[OUTPUT SKIPPED]

Any clues what might cause this?

EDK2 has recently changed the minimum required NASM level. See https://edk2.groups.io/g/devel/topic/89637409#87359

You will need to install 2.15.05 in order to build on Ubuntu 20.04.
