Incorrect Other/PIP Cron Instructions
In the instructions for other/pip for automatic renewal cron job should be sudo certbot renew -q instead of sudo renew -q

Hello, thank you for letting us know. We are correcting this issue with an internal ticket. Will update when fixed.
Another issue with the pip instructions.
The upgrade command is:
sudo /opt/certbot/bin/pip install --upgrade
but it should include package names to be upgraded. That would be, certbot, and if Apache, nginx, or a DNS plugin is selected, that package as well. See the original PR: https://github.com/certbot/website/pull/698.
@zoracon it looks like this most of this has been fixed. There's one little thing missing.
On https://certbot.eff.org/instructions?ws=nginx&os=pip the upgrade instruction is currently:
sudo /opt/certbot/bin/pip install --upgrade certbot-nginx
The certbot package should be included, in addition to any relevant plugin. This would be:
sudo /opt/certbot/bin/pip install --upgrade certbot certbot-nginx
