Error with click, Python 3 & missing UTF-8 locale

I get the following error (for full details see here):

[Mar 19 11:45:25] ERRO Task processing failed: Unexpected exit code [1] of container [6ad88087a20b step-54cc080860], container preserved

However, in meta.yaml I have the following lines:

extra:
  container:
    # click requires a unicode locale when used with Python 3
    # extended-base generates en_US.UTF-8 locale and sets LC_ALL, LANG properly
    extended-base: true  # [py3k]

This used to work, what am I doing wrong? @bgruening any idea?

Looks like this issue bioconda/bioconda-utils#70 @epruesse

Update: I restarted the the CircleCI check and then it runs fine (at least the Linux build does).
