certbot has a python problem on centos 7 about puppet-letsencrypt

[jhoblitt]

Installing python2-futures.noarch appears to resolve it. This is probably a metadata issue with certbot-1.6.0-1.el7.noarch but we may want to add an ensure_packages() if this is going to be a persistent issue.

I'd like to avoid adding workarounds here instead of fixing it upstream.

A trivial reproducer on CentOS 7:

yum -y install epel-release
yum -y install certbot
certbot --help # Note how this works
yum -y install python2-certbot-dns-route53
certbot --help # Not how this fails with DistributionNotFound: futures>=2.2.0,<4.0.0

In particular, this is listed in /usr/lib/python2.7/site-packages/s3transfer-0.1.13-py2.7.egg-info/requires.txt

# rpm -qf /usr/lib/python2.7/site-packages/s3transfer-0.1.13-py2.7.egg-info/requires.txt

A quick look in bugzilla, it appears this is https://bugzilla.redhat.com/show_bug.cgi?id=1834529

That suggests a packaging bug or possibly a locally installed pypi package where futures doesn't match that version spec. Not sure there's a lot we can do here.

This was on a fresh centos 7 test VM. I agree it could very well be a centos packaging problem. As this mod lists centos 7 in its metadata I thought it possible someone else had run into this. I will try to look into it today.

@ekohl Nice find! You beat me too it.

Note that the BZ issue has been open for over 2 months already.

[igalic]

soooooooo, how do we get someone who can do something about it to care?

[ekohl]

And by now the BZ has been closed as WONTFIX :(
