HTTPError: 400 client Error: user 'x' has no verified email addresses while pushing python package to pypi

HTTPError: 400 Client Error: User 'sampleuser' has no verified email addresse
s, please verify at least one address before registering a new project on PyPI.
See https://pypi.org/help/#verified-email for more information. for url: https:/
/upload.pypi.org/legacy/
The above error I am getting when I run " twine upload dist/* " command
Alright, I figured out:
You need to login to https://pypi.org/ instead of the old https://pypi.python.org/pypi.
https://pypi.org shows a "pre-production" warning on top, but that doesn't matter. Login to your account, go to account setting, and verify your email. The old site doesn't have a way to check whether your email is verified or not.
I am experiencing the same problem right now while trying to update a repo that's already on PyPi.
But I found this link on my profile page and on clicking it I read
we are experiencing issues with pypi.org and the upload.pypi.org
endpoint. we're actively working to resolve the issue and will update
here as we're able.

Cannot run VOLTTRON weather agent

Recently, we have been working on publishing and subscribing weather information for building load prediction. When we try to run the weather agent, there are errors as shown below:
We stick to every instruction in the VOLLTRON 3.0 user guide and it still doesn't work. How to fix that problem? Thank you!
This usually means that there is a problem with the key or a problem connecting with weatherunderground.
You can manually verify your key and connection with:
Replace with your own key
curl http://api.wunderground.com/api/<your key>/conditions/q/37918.json

Migrated Magento site from Localhost to Live. Getting and error

I have followed the relatively simple steps to migrating a Magento 2 site from my localhost to a live server. When I type in my new URL to see the site, I get an error screen with a message directing me to an error log.
From inside the error log I see the following error message:
a:4:{i:0;s:48:"SQLSTATE[HY000] [2002] No such file or directory";i:1;s:3133:"#0 /homepages/25/d336955856/htdocs/mfg_oldSite/product-catalog/lib/Zend/Db/Adapter/Pdo/Mysql.php(111): Zend_Db_Adapter_Pdo_Abstract->_connect()
I am not able to access either the regular public pages because of this error. I also get a 404 error when trying to access the admin page.
Any ideas? Any further info needed to make my question clear?
Check your host setting in /app/etc/local.xml
Try with changing it from "localhost" to "your server host"
have a look PDOException SQLSTATE[HY000] [2002] No such file or directory
EDIT
As per the whole discussion we have done. I am assuming that you have wrong credentials. this is why you are not able to connect to your DB.
have you checked your local.xml under app/etc or if you already done that then rename your local.xml and enter your website url on browser ,you will see installation panel, install your website again with right credentials i hope this work!!!
Hey please follow the following step it will remove the error
1) Rename the your local.xml file,
2) Delete all cache files form your system.
3) Run your site in your browser it will ask for the configuration steps.
4) Follow the steps and select the add database detail which you have updated in your live site.
It will setup all thing and the data will be same as it is.

Try cleaning your browser cache. By the message you've received, it can be a problem with your firewall also, you should disable it and try to reconnect to the bbb.
