Setting up on Ubuntu 14.04, trusty

Question

This is my current version of Ubuntu:

root@vps132318:~# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.2 LTS
Release:    14.04
Codename:   trusty

I know this question has been asked several times and I checked them all. For all of their cases, the problem was their current version of Ubuntu. Although I use the 14.04 version, and when I type

root@ssss:~# sudo add-apt-repository ppa:kurento/kurento
kurento/kurento
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --
homedir /tmp/tmp.mvnesaHwib --no-auto-check-trustdb --trust-model always --
keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --
keyserver keyserver.ubuntu.com --recv-keys

root@ssss:~# sudo apt-get update
W: Failed to fetch      
http://ppa.launchpad.net/kurento/kurento/ubuntu/dists/lucid/main/binary-amd64/Packages  404  Not Found
W: Failed to fetch http://ppa.launchpad.net/kurento/kurento/ubuntu/dists/lucid/main/binary-i386/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

root@ssss:~# sudo apt-get install kurento-media-server
Reading package lists... Done

E: Unable to locate package kurento-media-server

The two solutions I found around were:

add-key one; but for their cases, the --recv-keys part was giving them a key, so they were adding the key. Mine doesn't. Missing key is not given to me.
sudo update apt-get, however, no luck for me again.
I have also tried to apt-upgrade, no luck eithe.
Lastly, I tried clearing trusted.gpg.d directory, but no luck again.

Automatically importing all missing GPG keys. But when I try sudo launchpad-getkeys, this is what I get:

Trying to import all the missing keys

launchpad-getkeys has finished importing all missing GPG keys. Try running sudo apt-get update - you shouldn't see any key  errors any more.

Note that launchpad-getkeys imports missing GPG keys but does not fix broken keys.

And then sudo apt-get update:

Am I missing out something or doing something wrong?

The issue is that it's looking for a Lucid Lynx folder to find the packages for the kurento ppa. Problem is, that folder doesn't exist (and you don't want to use it anyway). Try doing sudo apt-get install ppa-purge followed by sudo ppa-purge ppa:kurento/kurento followed by reinstalling it with sudo add-apt-repository ppa:kurento/kurento — Mitch, May 10 '15 at 17:06
I did what you said. Here are the terminal console logs: 1) sudo apt-get-install ppa-purge . I ended up with bunch of errors. 2) sudo ppa-purge ppa:kurento/kurento . Here is the console log... — senty, May 10 '15 at 17:21

For whatever reason, there is a 10.04 PPA in your sources. Look closely at the erring URL:

http://ppa.launchpad.net/kurento/kurento/ubuntu/dists/lucid/main/binary-amd64/Packages

lucid is 10.04.

It's possible you have two entries of that PPA, one for 14.04, which you added just now, and one for 10.04, probably a hangover of some upgrade. Do grep lucid /etc/apt/sources.list /etc/apt/sources.list.d/*.list, find the offending entries and delete them.
