[SOLVED] Software won't install

[gertmoolman]

Well it seems I did something stupid , and can't fix it, when I try to add programs on ubuntu using the add remove programs thing I get the following error

"Failed to check for installed and available applications

This is a major failure of your software management system. Please check for broken packages with synaptic, check the file permissions and correctness of the file '/etc/apt/sources.list' and reload the software information with: 'sudo apt-get update' and 'sudo apt-get install -f'."

How do I fix this?

Sorry if this is a really stupid question , but I have only been running ubuntu for a week now

Did you run the suggested commands? That would be the first step. To do so you need to open a terminal (I believe Ubuntu has it under Applications->Accesories). You can just copy and paste this.

sudo apt-get update && sudo apt-get install -f

Post any error messages.

[gertmoolman]

Well I did that and this is what I got
For "sudo apt-get update"
I got "E: Type 'ntu/' is not known on line 45 in source list /etc/apt/sources.list"

For "sudo apt-get install -f"
I got
"E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?"

Seems wrong (typo) entry in sources.list file. Can you open the /etc/apt/sources.list file and copy and post the contents here.

[reed9]

It looks like there is an error in your sources.list. Please post the contents of /etc/apt/sources.list. (This is a text file, so you can open it in any text editor. Ubuntu has gedit installed by default.)

For the second error, it means some other package manager is using it. Make sure you don't have add/remove programs, synaptic, or the update manager running.

I can't post it ,cause it contains website URLs ,so I have attached it to this message ,and changed it from "sources.list" to "sources.txt"

The last line in your file should be like this

deb http://archive.ubuntu.com/ubuntu/ jaunty-security multiverse

Edit this file as root. To do so follow these steps
Press Alt + F2
Type gksu "gedit /etc/apt/sources.list" (with out the quotes) and press enter
Make the change and save the file.

Open a terminal and run the following command.
"sudo apt-get update" (again without the quotes).

Well , when I come to the save part it says :

"You do not have the permissions necessary to save the file. Please check that you typed the location correctly and try again."

oops a small typo on my part

Press Alt + F2 and type "gksu gedit /etc/apt/sources.list" without the quotes
