I must say, I ditched Ubuntu 18.04 as it comes with a lot of issues (related to other libs and tools). So, I did the test on a VM.

I guess the fix works but my installation fails with the Lmod version check, see below..

@mcakircali Do you mind retesting after defining $EASYBUILD_BOOTSTRAP_FORCE_VERSION such that the bootstrap script installs the previous version of EasyBuild (which doesn't require Lmod 6.6.3 yet):

export EASYBUILD_BOOTSTRAP_FORCE_VERSION=3.6.2

with 3.6.2, it works as expected..

Thanks for the feedback @mcakircali!

@akesandgren Were you planning to test this too? Should be good to go...
