After installing ubuntu 8.04
I tried to do an
           sudo apt-get install lyx

I get:   "E Couldn't find package lyx"

Actually the package should be found.

When I try

             sudo apt-get update

I get a long list of errors such as:

            Err http://security.ubuntu.com hardy-security Release.gpg
               Could not connect to  MyHostName:80 (  (111
Connection refused)


         W: Failed to fetch
Could not connect to MyHostName:80 ( - connect (111 Connection

Some possible sources of problems:

   During installation I was asked for an internet address.
I didn't know what setting to use to I left it blank.
I assume I should set my internet address to
How do I do this now?

   During Installation I was asked for HTTP proxy information.

   It requested information of the form:

   I answered with:   "MyHostName"

 If I must give a different value for the HTTP proxy
 what value am I supposed to give?
What is a HTTP proxy anyway?

 If my problem is elsewhere where is my problem?

Thanks in advance for any advice.
