Trying to install packages and it always gives me errors
 

I am running Ubuntu Hoary. Everytime I try to install a package like Flash player, it keeps giving me the following error:



So, I run the update. and get this at the end:


Im obviously new to Linux and have no clue how to do anything. What am I doing wrong here?

Thanks in advance!!

Please post the contents of /etc/apt/sources.lst.

Here is what I have:


#deb http://ch.archive.ubuntu.com/ubuntu/ hoary main restricted

deb http://at.archive.ubuntu.com/ubuntu/ hoary main restricted
deb-src http://at.archive.ubuntu.com/ubuntu/ hoary main restricted

Those addresses look valid? Which one(s) usually fail?

you're right. I changed it back to its original. I have problems when I try to install things. Like Acrobat reader:

sudo apt-get install acroread
sudo apt-get install mozilla-acroread
sudo apt-get install acroread-plugins

and it gives me this:
kyle@ubuntu:~$ sudo apt-get install acroread
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package acroread
kyle@ubuntu:~$ sudo apt-get install mozilla-acroread
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package mozilla-acroread

?
 

If... it may only accept certain web pages to update the files, are they accurate?

It's telling you that those packages do not exist.

As I said, I am new, Is there a place where I can see the packages that do exist? If I dowload the acrobat reader file, there is no .exe like in windows. I need to use commands to install it. Is there a good resource that you know that explains how to install linux applications?
