Kubuntu Source Installation Problems and no sound

Just downloaded and installed Kubuntu. It all installed fine, I booted up (had a few errors about the home directory not being writable, but I sorted that with a "chown" command). So now I need to set my internet up. I use ndiswrapper for my wireless card which requires the kernel sources to be present to install it.
I typed into the terminal:
sudo apt-get install linux-source-2.6.10
And it outputs the following:

Code:

edd@laptop:~$ sudo: unable to lookup laptop via gethostbyname()

Password:

Reading package lists... Done

Building dependency tree... Done

Package linux-source-2.6.10 is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or is only available from another source.

E: Package linux-source-2.6.10 has no installation candidate

edd@laptop:~$

Any idea what is going on here?

Also, I get an error about the sound when I boot up. The error is:

Code:

SOund server informational message:



Error while initializing the sound driver:



device: default can't be opened for playback (No such device)



The sound server will continue, using the null output device.

Any idea on that one?

Thanks a lot!

Check that page:

http://ndiswrapper.sourceforge.net/mediawiki

and first see if your card is supported by ndiswrapper.

If you cannot fix it, then get back here.
