I am trying to update Ubuntu 12.10 to version 13.04 but I have a download problem. I am using Lubuntu and use the 'software updater' but get the error during update:
W:Failed to fetch http://nz.archive.ubuntu.com/ubuntu/dists/maverick-backports/main/source/Sources 404 Not Found
, W:Failed to fetch http://nz.archive.ubuntu.com/ubuntu/dists/maverick-backports/restricted/source/Sources 404 Not Found
, W:Failed to fetch http://nz.archive.ubuntu.com/ubuntu/dists/maverick-backports/universe/source/Sources 404 Not Found
, W:Failed to fetch http://nz.archive.ubuntu.com/ubuntu/dists/maverick-backports/multiverse/source/Sources 404 Not Found
, E:Some index files failed to download. They have been ignored, or old ones used instead.
I have changed the download mirror to the main server but I still get the same error message. If you go the the page nz.archive.ubuntu.com etc the 404 not found error occurs. How can I get rid of the nz.archive.ubuntu.com URL.

Software Centre, Edit, Software Sources. Change "Download from... " to Main Server. Maybe?

If you are tying to update Ubuntu, why are you using Lubuntu to do it?

Just disable\delete them from the sources list.

Maverick is ancient anyway. Why the heck do you have that enabled in 13.04?

Yes, Maverick Meerkat (10.10) end-of-life reached on April 10, 2012.

You should definite delete the maverick-backports from your sources list.

Sometimes the source package lists become corrupted ... it happens occasionally. Try the following to refresh the package lists (after removing the Maverick backport source):



sudo -i
cd /var/lib/apt
mv lists lists.old
mkdir -p lists/partial
apt-get update
apt-get upgrade


Then if the above completes successfully you could try



apt-get dist-upgrade

to upgrade to 13.04.

Personally I'm a fan of doing clean installs with a newly downloaded iso. I keep my /home on a separate partition (so it is left untouched) but I'm being conservative in doing that as my priority is a stable system and I don't completely trust the dist-upgrade process.

I'm using an Ubuntu variant called Kubuntu (Ubuntu with KDE desktop environment) and my updates come from the same place (http://nz.archive.ubuntu.com)

Lubuntu is the 'light' Ubuntu. I have used Ubuntu 12.04 without any problem on my NEC versa L2200. When I upgraded to 12.10 I have many crashes and on a forum it was suggested the graphics card was not Ok for 12.10. Rebooted into Lubuntu and it has been working like a charm. Must admit I prefer the menu better that Ubuntu but then I could be a bit old fashion as i have XP on my PC! Now that the update to 13.04 is available the trouble in downloading has appeared.

Like you I prefer a start menu and is the main reason I switched from Ubuntu (with Unity) to Kubuntu (KDE). As you say, Lubuntu is a 'light' version of Ubuntu and will certainly run better on older PC's. I installed another 'light' version of Ubuntu called Xubuntu (XFCE) on my nieces old laptop some time ago and it ran rings around Windows XP that was on it before.

I like to stick to the LTS versions of 'buntus and ignore the interim releases because I've found they are just not so stable as the LTS versions. I will stick with 12.04 until the next LTS version probably. If you really want to keep up with the latest versions that's fine but maybe you're discovering the downside to that.

If you're still having the problem in your first post after removing the Maverick backport source I'm really puzzled.

I know of two Ubuntu 13.04 installs working fairly well.

I use 'http://ucmirror.canterbury.ac.nz/ubuntu' to update.

13.04 is slicker and faster than 12.04 because of these very complaints about previous versions.

Go to System Settings/Software & Updates choose mirror above and go to Updates Tab select Daily and whatever you want in updates then reboot.
