> Fedora 30: ImportError: libnsl.so.1 when importing apache_beam in Python 3
> --------------------------------------------------------------------------
>
> Key: BEAM-8110
> URL: https://issues.apache.org/jira/browse/BEAM-8110
> Project: Beam
> Issue Type: Bug
> Components: dependencies, sdk-py-core
> Affects Versions: 2.15.0
> Environment: Fedora 30, Singularity container
> Reporter: Robert Lugg
> Priority: Minor
>
> {{When importing apache_beam in python, it fails because it can't find
> libnsl.so.1.}}
