Hey guys, I've been trying to update ubuntu in the last week and it seems that every time it tries to, it gets a few errors, the thing is that I'm not sure what the problem is, after "updating" it seems fine, but then an icon appears in the task bar like this one: (I'm not sure if this is the best way to upload a pic, srry)

and in Terminal I get a few of these:

Err http://ppa.launchpad.net precise/main Sources 404 Not Found
Err http://ppa.launchpad.net precise/main i386 Packages 404 Not Found
W: Failed to fetch http://ppa.launchpad.net/unity-team/ppa/ubuntu/dists/precise/main/source/Sources 404 Not Found
W: Failed to fetch http://ppa.launchpad.net/unity-team/ppa/ubuntu/dists/precise/main/binary-i386/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

So, thanks for any help in advance.

You need to either remove or just uncheck those PPAs in your sources list.

I'd comment out the offending lines in the /etc/apt/sources.list file with a # in front of the offending lines.

Ok, thanks for the advice, I did uncheck only, as I'm not sure or at least in the Preference menu doesn't say the same, I just unchecked the ones that don't look necessary :)

MaynardHSH; Hi !

Did you see the "bad" PPAs line in either /etc/apt/sources.list OR the directory /etc/apt/sources.list.d (terminal use)and comment out or remove;
alternately as suggested, find and uncheck those PPAs in Software Sources (GUI) ?? //only those that are generating the "404 not found" errors//
Then run the terminal codes:

sudo apt-get update
sudo apt-get upgrade again and see what errors are now present.

If you require additional assistance, post the output of terminal codes:

cat /etc/apt/sources.list
ls -la /etc/apt/sources.list.d

just try'n to help
