What do I need to do to get Software Updater to work though I'm connected and can browse the internet?
Each time I try to update I'm met with the message
Failed to download repository information. Check your internet connection.
My browsers work just fine and I know I'm connected. However, updater is not. Now I see on my desktop menu bar this caution symbol (⚠) that when click states along the lines that my software needs updated.
I'm using a wired connection through a router to a modem to the ISP. I'm using Ubutnu 14.04 LTS. The icon indicates that my software is out of date. It's a vicious circle, how do I fix this?
Edit: I would post the paste from terminal when I used
grep --ignore-case trusty-updates /etc/apt/sources.list
but it says I need ten reputation to post more than two links. It lists the us.ubuntu.com links six times and lists them in pairs saying main restricted, universe and multiverse.
