</div>You could have taken a much shorter route by directly upgrading from<br>
10.04 LTS to 12.04 LTS - but unfortunately it is too late now.<br>

</div>The problem with these ancient releases is that the repositories were<br>
moved from the standard server to <a href="http://old-releases.ubuntu.com" target="_blank">old-releases.ubuntu.com</a>. In the file<br>
/etc/apt/sources.list you should change the server names accordingly.<br>
Then the entries would look like this:<br>
<br>
deb <a href="http://old-releases.ubuntu.com/ubuntu/" target="_blank">http://old-releases.ubuntu.com/ubuntu/</a> maverick main restricted multiverse universe<br>
<br>
To edit the file you need root privilege. You can do it with a command<br>
like<br>
<br>
gksu gedit /etc/apt/sources.list<br>
<br>
in a terminal. And you will probably have to do the same for some more<br>
upgrades. For more details have a look at [1].<br>
<br>
But I would suggest that you save yourself a lot of time and do a fresh<br>
install of the latest version directly. Either 12.10 which was released<br>
a few days ago, or 12.04 LTS if you prefer to keep one release for a<br>
longer time. You can preserve the files in your home directory if you<br>
select manual partitioning and select the currently used partition(s)<br>
but NOT format them.<br>
<br>
