When switching to python3_6, acme is missing requests-toolbelt as dependency, causing following traceback when calling certbot: # certbot Traceback (most recent call last): File

which version of acme?
(In reply to Matthew Thode ( prometheanfire ) from comment #1) > which version of acme? app-crypt/acme-9999 (sorry for the late answer, i did not see your question).
all versions of acme in tree require it (and have it). Looks like I fixed it a while back. Closeing (thanks for the update)
