I typed the command

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

and got the following error

W: Failed to fetch http://old-releases.ubuntu.com/ubuntu/dists/precise/main/source/Sources  404  Not Found

and similar other messages

Previously, I had typed the following commands from an answer on this site Upgrading to a no longer supported version

username-M:~$ sudo cp -v /etc/apt/sources.{list,backup}
[sudo] password for username: 
'/etc/apt/sources.list' -> '/etc/apt/sources.backup'

username:~$ sudo sed -i 's/us.archive/old-releases/' /etc/apt/sources.list

the problematic sources.list file

Your should reset your repository by resetting sources.list file which will be in /etc/apt/sources.list

Visit http://repogen.simplylinux.ch/ to generate the new sources.list file according to your Ubuntu version

Backup sources.list before you do something destructive like an in-place sed replace on it in the future

e.g. sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup.

The problem is that your trying to use the process for updating from an unsupported release, when your release is still supported.

This is shown by your error line

W: Failed to fetch http://old-releases.ubuntu.com/ubuntu/dists/precise/main/source/Sources  404  Not Found

It has the release name 'precise' in there, which relates to 12.04, a still supported release. The precise repositories will still be available in us.archive.ubuntu.com and hasn't yet been moved to the old-releases server.

You can reset your sources.list file from your backup with the command:

sudo cp /etc/apt/sources.backup /etc/apt/sources.list

After that your apt-get commands should work.

Edit:

It looks like your /etc/apt/sources.backup file contains the same lines as the /etc/apt/sources.list file, so it would be prudent to make another backup of this sources.list file, then try to correct the switch from us.archive.ubuntu.com to old-releases.ubuntu.com.

Make a new backup with:

sudo cp -a /etc/apt/sources.list /etc/apt/sources.secondbackup

And do the reverse of your previous sed command:

sudo sed -i 's/old-releases/us.archive/' /etc/apt/sources.list

Then to check that it has worked, just do the update part of your apt-getcommand:

sudo apt-get update
