Could be an issue with your internet connection.

Hello,
The only errors I see here appear to be permission related, not network related. I was unable to replicate any issues with reaching github.com when creating another droplet. You may want to review this information as it appears to have some tips for the first error I see

If you would also like to give us a ping/traceroute to github.com we can make sure you are able to communicate with them. You can run the following commands:

ping -c5 github.com
traceroute github.com

If you can give us those results we can ensure you have a connection to github.com.

Let us know if you have any other questions!
