[Chicago] Digital Ocean, pip, and UFW on Ubuntu

[Aaron Elmquist]

Sure thing.

pip install requests

Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after
connection broken by
'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection
object at 0x7f01a85fa390>: Failed to establish a new connection: [Errno -3]
Temporary failure in name resolution',)': /simple/requests/

This repeats 4 more times.  I see 5 times is the default in the docs.

Could not find a version that satisfies the requirement requests (from
versions: )
No matching distribution found for requests

By the way temporarily disabling the firewall resolves this.

sudo ufw disable

Collecting requests

sudo ufw enable

Toggling the firewall is probably bad.

Output from  sudo ufw status:

Thanks for the help.
