Necessary Ubuntu update?
 

I'm currently using Ubuntu Linux 8.04 Hardy and have my Update Manager set for notifying me if it has new updates to install rather that to do it automatically. The problem I have is with the newest update:
"Version 2.6.24-21.33:

[Stefan Bader]

* ndiswrapper: Prevent buffer overflow if nickname is IW_ESSID_MAX_SIZE
characters long.
- LP: #275860

Which doesn't sound tremendously horrible if installed. However, when I read the description for the above, I was set into a quandry. What follows is the description for this update.

This package contains modules supplied by Ubuntu for Linux kernel 2.6.24 on x86/x86_64.
You likely do not want to install this package directly. Instead, install the linux-generic meta-package, which will ensure that upgrades work correctly, and that supporting packages are also installed.

What bothers me is that it says that I don't want to install it "directly". So what do I do with it? I've done searches for the "linux-generic meta-package" and can't find anything really relevant. I have been keeping up with all the updates, so is it okay for me to install this?

Yes, I'm still very new at using Linux and Ubuntu. I don't want to make any mistakes and necessitate a reinstallation...

Thanks for your due consideration ahead of time.

Don't worry too much - linux-generic is already installed.

You can update safely.

If you want to see info about any package you can use these:

apt-cache search <some_part_of_package_name>

Once it gives you the full name of the package i.e. linux-generic you can get more info by:

apt-cache show linux-generic.

If you want to know if some package is already installed on your system and know at least part of the name of that package do:

dpkg -l | grep <some_part_of_package_name>

Thank you!
