404 errors from apt-get update

**qcdisciple** · October 8th, 2011

I'm using natty 64 bit on a lenovo laptop. I tried to install google chrome by downloading the deb and opening it in the Software Center. It said package files didn't download. I looked online and decided to try to fix my sources.list file. I used a generator to make a new file with just the basic repositories. When I tried to update, this came out:

Hi and welcome to the forums

You may need to try switching to the Main Server from whatever is set as your current download mirror.

You can do this either in Synaptic or the Ubuntu Software Center.

**qcdisciple** · October 17th, 2011

It worked at first, but when I tried to upgrade to 11.10 it said that it couldn't authenticate a bunch of packages.

**subehsharma** · November 10th, 2011

Best method to getaway from this problem is to install fix404. You can read about it more here:

Under Ubuntu, the APT package index is a database containing all packages of repositories (PPAs) defined in the /etc/apt/sources.list file. To update this database after adding some repositories, we need to use this command from the Terminal:

sudo apt-get update

Sometimes, when running the command given above, we get error messages (404 Not Found) that are the result of wrong PPAs, which may slow down the update process via the Terminal. In fact, this 404 Not Found error messages are not harmful at all, but you can use Fix404 to detect and remove these PPAs.

To install Fix404 on Ubuntu 11.04, launch the Terminal and run these commands:

sudo apt-add-repository ppa:lkjoel/fix404
sudo apt-get update
sudo apt-get install fix404

To install on Ubuntu 10.10/10.04, download this deb package here.

To start using Fix404, run this command (root privileges required):

sudo fix404

Then follow displayed instructions to disable PPAs causing the 404 Not Found Error.

I'm still having trouble. There is an error authenticating packages when I try to update or upgrade. Look at the sceenshot to see exactly what happens.

**oldos2er** · November 11th, 2011

Can you run

Code:

sudo apt-get update

in a terminal, and post the output here?

**qcdisciple** · November 12th, 2011

I've tried it a bunch of times before. I always get the same errors.
