Bug 576400 – app-crypt/letsencrypt-0.4.1 -- The 'parsedatetime<2.0' distribution was not found and is required by letsencrypt

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Gary E. Miller 2016-03-04 00:40:06 UTC]

letsencrypt-0.4.0 worked great for me.  After update to 0.4.1 not so much.

A re-emerge, python-updater, revdep-rebuild, etc. no help.

Here is the failure:

I see my parsedatetime is too new (>=2.0)

kong ~ # eix parsedatetime

Downgrading to dev-python/parsedatetime-1.5::gentoo fixes my letsencrypt 0.4.1
installation.

[Comment 3 Steve Herber 2016-03-05 07:37:48 UTC]

I had the same problem but downgrading my parsedatetime to 1.5
uncovered another version problem:

# letsencrypt
An unexpected error occurred:

Please try again with 0.4.2

[Comment 5 Gary E. Miller 2016-03-06 22:54:11 UTC]

0.4.2 works fine for me.  I tried on 2 unstable gentoo hosts.

Thanks!
