I am trying to download gcc using apt-get install on Ubuntu 9.04 Jaunty, but when apt-get is trying to download the file I receive an error:

WARNING: The following packages cannot be authenticated!

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

apt-get update and --fix-missing are not solving the problem.

How can I solve it?

Answer 1

I managed to solved the problem by editing the /etc/apt/sources.list file and replacing all instances of archive.ubuntu.com and security.ubuntu.com with old-releases.ubuntu.com. After that, I ran sudo apt-get update to update the indexes.

Answer 2

See here: http://mt.archive.ubuntu.com/ubuntu/dists/ – Jaunty is missing.

Your Version of Ubuntu is too old. The Jaunty repository is not more available. I think you need to upgrade to a newer version of Ubuntu.

Answer 3

This little script performs the correct string replacements in sources.list and updates the package list:

cd /etc/apt
sudo cp sources.list sources.list.bak
sudo sed -i "s/archive./old-releases./g" sources.list
sudo sed -i "s/\/security./\/old-releases./g" sources.list
sudo apt-get update
