add software

gksudo gedit /etc/apt/sources.list

copy the lines starting with the word:

deb

and paste them at the BOTTOM of the sources.list file

Save the new file and close gedit

In terminal type:

sudo apt-get update

You can now install the software from those servers. If you get any GPG warnings then paste the full output of the command and I'll give you the commands to get the keys

Had those lines in /etc/apt/sources.list
Ran sudo apt-get update
and saw (among others)

Why are many of these entries being ignored? (Ign)

Thus, I believe it is reading the sources.list
However, I can still not fine these applications in the add/remove
software list.

The Ign ones are either down or do not exist. The servers are read from the sources.list

If they are not in add/remove then the repositories do not hold what you need

As you can see 'Ign' lines are Translation packages, nothing to update there. (Same in Hardy here, nothing to worry.) For your comfort you may check system administration -> supported languages

btw.
Add/Remove isn't very advanced, hence Synaptic (or apt-get via CLI) is the choice.

I only use apt-get, synaptic hides all the good output when things go wrong.

Thanks. That worked. It is unfortunate that Add/Remove has problems.

Related question, I have a AMD-64 processor (8.10-2.6.27-14-generic).
When I installed one of the packages, I was offered 32-bit libraries
only. Apparently, the person who installed Ubuntu after my disc crash
failed to do something correctly. I would prefer to use the 64-bit
libraries. How can I correct this problem, or should I simply try to
reinstall Ubuntu?

Possible that the other user installed 32bit Ubuntu on 64bit architecture, it's common practice, because some users like certain apps which (still) are only available in 32bit.
If you type in terminal:
uname -a

it will show at the end of the line which Ubuntu was installed. It says either x86_64 or i686 GNU/Linux.
In case of i686, simply download 64bit .iso and install.

btw. the Add/Remove issue will be past sooner than later.
