KeyError: 'No metadata except PKG-INFO is available'


#1

Hi,

I’m encountering below error when installing using certbot-auto on Amazon Linux for Nginx. Previously I was able to install on another instance without this error. Anyone has an idea on this?

#./certbot-auto --nginx
Error: couldn't get currently installed version for /opt/eff.org/certbot/venv/bin/letsencrypt: 
An unexpected error occurred:
KeyError: 'No metadata except PKG-INFO is available'
Please see the logfile '/tmp/tmpJEWQLs' for more details.

I was getting the same issues with an Amazon Linux instance that was orginaly setup with cert-bot and worked fine. I tried to fix some other issues by follwing another post and this is the result I came too

In the end I had to do the following

rm -rf /opt/eff.org/*

It will probably fail on this one but setups a clean virtual enviroment
./certbot-auto --debug

cd /opt/eff.org/certbot/venv/lib64/python2.7

mv site-packages site-packages.sav

ln -s dist-packages/ site-packages

Your now ready to run certbot-auto again

./certbot-auto --debug

Wow this works well. Thanks a lot!
