Noticed that the new LTS is out and got a notification pop-up, but when I try and upgrade it Comes up with the following:

W:Failed to fetch http://ports.ubuntu.com/dists/xenial/main/binary-amd64/Packages  404  Not Found [IP: 91.189.88.150 80]
W:Failed to fetch http://ports.ubuntu.com/dists/xenial/restricted/binary-amd64/Packages  404  Not Found [IP: 91.189.88.150 80]

W:Failed to fetch http://ports.ubuntu.com/dists/xenial/restricted/binary-i386/Packages  404  Not Found [IP: 91.189.88.150 80]
E:Some index files failed to download. They have been ignored, or old ones used instead.

Then, when I click close it reverts any changes its made. I have the update server as 'Main Server'. Our internet connection is stable

concise sources.list: (i removed the double commented lines)

  • Ok, try replacing ports in the last two lines of sources.list with archive and then running the sudo apt-get upgrade.

  • Actually, you could just comment out the second to last line and replace the ports with archive in the last line.

Reset to default

You can try this: Enter the follow commands in a Terminal

sudo rm /var/lib/apt/lists/* -vf

Then:

sudo apt-get update

The first command will delete your local repo cache (it seems sometimes they can get into an inconsistent state) and apt-get update will refresh the whole thing from source.
