Failed to fetch update on Ubuntu 14.04 LTS (Trusty Tahr) [duplicate]

In short, I haven't been able to update any of my Linux Mint/Cinnamon 17.1 installs (3 installs on 3 different machines) for the last 3 days due to being unable to connect to any "

archive.ubuntu

" or "

security.ubuntu

" source either by the terminal (apt-get update) or by MintUpdate (the Update Manager). Accessing Mint sources or sources from Launchpad from a PPA is no problem. It's only the "

archive.ubuntu

" or the "

security.ubuntu

" sources as defined by the "/etc/apt/sources.list.d/official-package-repositories.list".

These are all recent installs and updating was working 3 days ago and ever since initial installation without a single problem and there's been no change to any of the installs over the last 3 days.

There is only one PPA installed (Mozilla security PPA for Firefox and Thunderbird) and it's not the problem.

Also, I'm hardly a "Newbie" no offense to anyone) as I have several years experience running Linux Mint but there...

I'm running Ubuntu Server 14.04.2 LTS
When running sudo apt-get update, most of the packages install, but some are rejected. I had my network guy open port 80 to those IP addresses but a number of them still failed. Is that because they don't exist anymore or is there likely more that I need to do network/server side to get the update to complete?

Running $ sudo apt-get update takes about 6 hours. When it's done, I generally come across a number of errors including 404 Not found errors and others.
I tried $ sudo apt-get upgrade after running update; I get
"Reading package lists... Error!"
"Encountered a section with no package: header"
"Problem with MergeList /var/lib/apt/lists/..."
"The package lists or status file could not be parsed or opened"
(I get the same thing with a $ sudo apt-get check)

I have found a few discussions on this topic that suggest running:
$ sudo rm /var/lib/apt/lists/* -vf
Then running update again, which,...

Hiya Monk-

Sorry I missed the followup question, must have been a busy day for me.

As for backing up, personally I like to boot off of a Linux boot CD like an Ubuntu live or Knoppix disk, attach an external hard drive of large enough capcity, and use 'dd' to image the entire drive block by block. Let's say the drive you want to image is /dev/hda and your removable disk shows up as /dev/hde, you'd use the following:

dd if=/dev/hda of=/dev/hde conv=sync,noerror bs=1k

Tar is great for a lot of things, but a rollback would involve reinstalling the old OS to a base state, whereas with the 'dd' method, though a bit arcane, you can just boot back with the boot cd and reverse the 'if' and 'of' (input-file and output-file) arguments and reboot:

dd if=/dev/hde of=/dev/hda conv=sync,noerror bs=1k

Now, one thing tar is phenomenal for is the fact that you can use it in conjunction with dd to compress the dd image and pipe it directly to a file on...

This guide has been deprecated and is no longer being maintained.

Ubuntu 14.04 is a long-term support (LTS) release that will be supported until April 2019. This guide explains how to upgrade your Linode from Ubuntu 12.04 (Precise Pangolin) to Ubuntu 14.04 (Trusty Tahr).

Distribution upgrades can yield unpredictable results, due to variations in software stacks. When possible, we recommend:

Creating a new Linode with the latest disk templateRebuilding your stackTransferring your dataSwapping IP addresses

In addition, you should use LISH to perform this upgrade as, in the event your internet connection is disconnected, your system may end up corrupted or the upgrade may be incomplete.

This guide was written assuming that you have root access to your Linode. If you do not have root access, you will need to prepend each command with sudo.

Since the release of the 5th Ubuntu LTS, Ubuntu 14.04, two other versions have emmerged, Ubuntu 15.04 (Vivid Vervet) and Ubuntu 15.10 (Wily Werewolf). Many have upgraded their ubuntu versions to the Ubuntu 15s except the core users of LTS who wouldn’t trade anything for the LTS because of its stability and most importantly, the Long Term Support that comes with it.

I’m using Ubuntu server 14.04.1 LTS and have installed Docker 1.4.1 by adding the official Docker repo to apt. So far so good. After installation I have added my user to the Docker group, so I’m able to run docker with my own user. Docker version output is:

Client version: 1.4.1 Client API version: 1.16 Go version (client): go1.3.3 Git commit (client): 5bc2ff8 OS/Arch (client): linux/amd64 Server version: 1.4.1 Server API version: 1.16 Go version (server): go1.3.3 Git commit (server): 5bc2ff8

Now my problem: when I run the docker command below, the container is unable to connect to the Ubuntu host. Some Googling told me that it has to do with IP6, but unfortunately I was unable to fix this.

Docker command:

docker run --name="test" ubuntu:14.04 apt-get update

And the corresponding output:

How to upgrade Ubuntu 14.04 LTS to Ubuntu 14.10

Upgrade Ubuntu 14.014 to Ubuntu 14.10 Guide

Canonical won’t be nudging users of 14.04 LTS to upgrade to the interim release of 14.10.

But that doesn’t mean that you can’t upgrade your rock solid Trusty Tahr desktop to the (slightly underwhelming) Utopic Unicorn.

To get notified of new non-LTS Ubuntu releases you need to “opt-in” via the Software & Updates tool. This is straightforward.

Open ‘Software & Updates’ Select the ‘Updates’ tab Locate section titled ‘Notify me of a new Ubuntu version’ In the dropdown menu switch from ‘For long-term support versions‘ to ‘For any new version’

After switching you’ll want to run a quick update.

Now you’re all set! The moment Canonical send out the “upgrade” prompt to...

Bower is package management solution. It runs on Node.js and uses Git to fetch and install most packages. In this tutorial we will install Bower on Ubuntu 14.04 LTS.

Install bower on your Ubuntu

Bower requires git to be installed as some bower packages require it. First thing is to install Git. You can install it with the following command:

$ sudo apt-get install git-core

Bower depends on Node and npm so first you will need install NodeJs.

$ sudo apt-get install nodejs

Now is NodeJs installed and executable as /usr/bin/nodejs

If you try run /usr/bin/env node this end with error:

$ /usr/bin/env node /usr/bin/env: node: No such file or directory

Forget something like symlink. (ln -s /usr/bin/nodejs /usr/bin/node) Just install nodejs-legacy. This package create a symlink for you.

$ sudo apt-get install npm-legacy

Symptoms

: When using

apt-get

or some other GUI package management application to install a new package on Ubuntu or Debian Linux the following error message appears:

W:Failed to fetch cdrom://Ubuntu 14.04 LTS _Trusty Tahr_ - Release amd64 (20140416)/dists/trusty/main/binary-amd64/Packages Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs

Solution

: When Ubuntu or Debian Linux are installed using CD-ROM media this system will retain CD-ROM in its

/etc/apt/sources.list

file as a repository source. To avoid this error message is to re-insert your Ubuntu/Debian Linux installation media before running

apt-get

command or remove/comment this CD-ROM repository source directly from

/etc/apt/sources.list

. Using your text editor open

/etc/apt/sources.list

file and comment or remove lines that include CD-ROM. eg:

I'm running Ubuntu 14.04 and havent run sudo apt-get update for many months.
When I try to update local /etc/apt/sources.list apt-get can connect to many repos no problem, but many (maybe 15% of total) return errors like this

W: Failed to fetch http://nz.archive.ubuntu.com/ubuntu/dists/trusty-backports/multiverse/binary-i386/Packages 403 Forbidden W: Some index files failed to download. They have been ignored, or old ones used instead.

I'm wondering if the repo addresses or configurations have changed since my machine last made contact, and therefore I need to go through some process to completely flush and then re-establish the /etc/apt/sources.list? I'm thinking something like

sudo apt-cache clean

But I don't want to bork my system any more than it already is.
How can I resolve this 403 Forbidden error?
