Fail to upgrade due to network/server problem

Asked by Han Shan on 2013-01-31

Good day!

When I try to upgrade from 11.10 to 12.04 in the update manager, first the release notes window pops up, then after clicking upgrade, the upgrade tool files are downloaded. Right after that, an error message I get, saying: 'Authenticating the upgrade failed. There may be a problem with the network or with the server.'
Could anyone find a solution to this?

Much appreciated,
Han Shan

The easiest solution to that problem is to download the .iso image of 12.04.1 LTS and burn in to a CD/DVD or USB . Boot from there and install Ubuntu from scratch.

Of course you must backup first all your sensitive data because everything will be lost.
Ubuntu 12.04 LTS has a 5 years of support and for that you will not be forced to upgrade again for next 5 years (until April 2017) if you don't want.

Download the iso from here:

Follow a guide on how to make a bootable Usb-stick , for example you can use Unetbootin:

Backup your personal data to an external HDD.

Configure your BIOS to boot first from USB-stick .
Boot with usb-stick attached and a Ethernet cable (more stable connection than WiFi) and install Ubuntu 12.04.1 LTS.

Enjoy !


What is the output of:

sudo apt-get update

To NikTh:

Thank you for your reply.
I am sorry I didn't specify that I had a kind of solution in mind that didn't involve backing up everything and doing a clean install.
That remains to be the final option, of course.

What is the output of:

lsb_release -a; uname -a


Han Shan (reynholm) said : #6

It says that no lsb modules are available

ok, what is the output of:

cat /etc/issue


Han Shan (reynholm) said : #8

This is what I got:

Ubuntu 11.10 \n \l

Disable the backports repo. Can help

Han Shan (reynholm) said : #10

Tried it. No luck. Thanks anyway.

Han Shan (reynholm) said : #11

Anyone else with a possible solution?

Manfred Hampl (m-hampl) said : #12

Before you can do a version upgrade, you have to make sure that you current release is up-to-date and that your package management system is clean.

The output of the apt-get update command shows that you have a wrong setting in the list of repositories. In addition to the oneiric sources, you still have maverick-backports enabled, which does not fit together.

My advice:
disable maverick-backports from your sources
try the following commands

sudo apt-get update
sudo apt-get upgrade

If there is any warning or error, please follow steps 1 to 6 of with the only exception that in step 6 you should not create a new question, but should continue in this current question document.

Can you help with this problem?
