Like a bunch of other questions, I can't run apt-get update
sometimes. Restarting or waiting for a while makes the problem go away. I never have issues pinging or visiting the respective URLs in a browser.
I've tried every up-voted answer to no avail. What is apt
doing that is so different to ping
or my browser? For example, when I run apt-get update
I see this:

And visiting the page in my browser works fine. How can I make apt-get
"just work"?
Here is the contents of my /etc/apt/resolv.conf
