FreeBSD error

[Fastidious]

After installing (from ports), I get this error:

An unexpected error occurred:
VersionConflict: (acme 0.8.1 (/usr/local/lib/python2.7/site-packages), Requirement.parse('acme==0.5.0'))
Please see the logfile 'certbot.log' for more details.

The certbot.log contains:

What condition are your ports in? I don't see the same as you.

I see:

root@piglet:~ # pkg which `which certbot`
/usr/local/bin/certbot was installed by package py27-certbot-0.8.1,1
root@piglet:~ # pkg info -d py27-certbot-0.8.1,1 | grep acme
        py27-acme-0.8.1,1
root@piglet:~ #

[Fastidious]

Brand new FreeBSD install. All ports up-to-date.

[Bobzikwick]

I'm not a python guru, but does your computer really say:

# pkg which `which certbot`
/usr/local/bin/certbot was installed by package py27-certbot-0.8.1,1

[Fastidious]

Yup.

root@daemon:/usr/ports/security/py-certbot # pkg which `which certbot`
/usr/local/bin/certbot was installed by package py27-certbot-0.8.1,1
root@daemon:/usr/ports/security/py-certbot # pkg info -d py27-certbot-0.8.1,1 | grep acme
    py27-acme-0.8.1,1
root@daemon:/usr/ports/security/py-certbot # 

[Bobzikwick]

Well, looking at your error:
VersionConflict: (acme 0.8.1 (/usr/local/lib/python2.7/site-packages), Requirement.parse('acme==0.5.0'))

In my /usr/local/lib/python2.7/site-packages/certbot-0.8.1-py2.7.egg-info/requires.txt file I have a line:
acme==0.8.1

What does yours say?

[Fastidious]

The same. Complete requires.txt:

To add to this, a portmaster -a will always render certbot as available to re-install:

root@daemon:~ # portmaster -a

    ===>>> The security/py-letsencrypt port moved to security/py-certbot

Your requires.txt is identical to mine
I just ran certbot renew again to be sure and it worked ok...

I would have thought portmaster would do the right thing. I didn't use it though. I use pkg or make. Looks like a FreeBSD ports problem to me rather than a certbot thing.

[Fastidious]

I have pinged the maintainer to see if he can shed some light.

[koobs]

Tracking in FreeBSD Issue #210617

If the root cause turns out to be the port, I'll reference this issue in the commit message

Long term, it would be great for all certbot requirements to be >=

[koobs]

Issue has been resolved.

Cause: stale/multiple letsencrypt versions due to use of pip to install/manage/update packages in system site-packages rather than strictly ports/packages. pkg_resources importing the older version, resulting in the mismatched (stale) version requirement

[bmw]

Great! I'm glad this was resolved.

[jmarca]

@koobs can you post a quick synopsis of how to clean up the issue? I am hitting the same problem on slackware linux, but my python skills are super weak.

update: What seems to work okay for me is:

sudo pip uninstall letsencrypt

then sudo pip list | grep encrypt and sudo pip list | grep certbot to make sure all is cleaned up.

[Fastidious]

@jmarca did as you wrote, yet each time I run portmaster -a it will re-install py27-certbot-0.8.1,1. Running pip list |grep encrypt renders no results, while pip list |grep cerbot renders certbot (0.8.1). Any idea on what to do from here, @koobs?

[koobs]

@Fastidious Don't use pip to manage system site-packages? :)

[Fastidious]

@koobs I didn't. I have not used pip, I first used the ports (make install), then I used pkg to install. Still py27-certbot will insist on re-installing each time.

[koobs]

@Fastidious Let's take this off upstreams issue tracker :) Email me the full log of pkg version -v | grep certbot -> install certbot with portmaster and we'll go from there. I'm koobs freebsd org

[vbotka]

For the record.:

 pkg_deinstall py27-certbot
 pkg_deinstall py27-letsencrypt
 portinstall -R py27-certbot

solved the problem.
