"sudo apt-get update" packages 404ing in linux mint nadia

Solution 1:

In some cases if you switch to 'Server for United Stages' solves your problem. Because, the selected server if not synced with the mains would result in 404s.

Solution 2:

I haven't verified this article, but check it out and see if modifying the /etc/apt/sources.list will fix your problem.

Solution 3:

What you should do is edit your /etc/apt/sources.list file to make it look like this: (you can edit with gedit as superuser, or vim using sudo or however you like it the most)

deb http://packages.linuxmint.com/ nadia main upstream import
deb http://archive.ubuntu.com/ubuntu/ quantal main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ quantal-updates main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu/ quantal-security main restricted universe multiverse
deb http://archive.canonical.com/ubuntu/ quantal partner
deb http://packages.medibuntu.org/ quantal free non-free

#deb http://archive.getdeb.net/ubuntu quantal-getdeb apps
#deb http://archive.getdeb.net/ubuntu quantal-getdeb games

then make an update

sudo apt-get update

and the upgrade

sudo apt-get upgrade

You shouldn't see that error anymore...
