ENVY asking for linux headers

[type3]

Hi all,
I'm trying to my 7950's running with the proprietary drivers using ENVY. However ENVY says:

Bad luck, the kernel headers for the target kernel version could not be found and you did not specify other kernel headers to use.

I tried using:

sudo apt-get install linux-headers-$(uname -r)

...but that returns...

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package linux-headers-2.6.20-16-386

What am I doing wrong? I've used Envy under Feisty with no problems before, Gutsy just won't play ball.

Thanks.

Re: ENVY asking for linux headers

If this is an exact replica of your command:

sudo apt-get install linux-headers-$(uname -r)

then it is not "well formed". It needs to be like this:

sudo apt-get install linux-headers-`uname -r`

Are you using the latest version of Envy? I'm surprised that Envy didn't take care of this by itself.

Try it the way I recommended -- let's see what happens.

'cause I'm curious, so ...

If sudo apt-get install linux-headers-$(uname -r) is wrong, then how come it ultimately returned the error: E: Couldn't find package linux-headers-2.6.20-16-386 Apparently $(uname -r) in the package name is equivalent to `uname -r` or am I missing something here?

Re: ENVY asking for linux headers

Well, that is odd, and I can't explain it, for sure. It appears that the system attempted to interpret the command, rather than simply reject it as invalid. Maybe the characters "$( )" are not illegal, and it went looking for such a kernel-headers package, and of course it didn't find one.

If his kernel version is actually 2.6.20-16-386, and it actually can't be found by the package manager, then there's a whole different problem involved. But first I'd like to see the command issued correctly.

Re: ENVY asking for linux headers

Just conducted a little test:

echo $(uname -r)

Which returns:

paul@paul-toshiba-laptop:~$ echo $(uname -r)
2.6.20-16-generic

Re: ENVY asking for linux headers

Hmmmmmmmmmmmmm.

Well, perhaps (as in so many things Linux) that is another legal format for the command. It's not one I've seen recommended anywhere, but if if it works ......

On the other hand, there's a keystroke to be saved by using `uname -r`, isn't there?

Re: ENVY asking for linux headers

$(foo) is intercepted by the shell and expanded.
`foo` is equivalent to $(foo) (and the `foo` form is deprecated and should be avoided).

The problem is that the package just isn't there. The 2.6.20 kernel packages have been removed from the repositories. The solution is to install a newer kernel.
(In fact, the only kernel header packages available are 2.6.22-13-* and 2.6.22-14-* (and some miscellaneous Xen kernel headers).)

Aha!

Well, thank you SheeEttin -- I learned something tonight!

The solution is to install a newer kernel.

Is this analogous to installing a 'newer version' of *ubuntu - i.e., Gutsy? Running Feisty, the kernel version (which is up to date) is 2.6.20-16-generic

Ah okay. I'm not going mad then. I do have a newer kernel (2.6.22-14-386) installed but it's completely broken. See here:

http://kubuntuforums.net/forums/inde...opic=3088720.0

I used the slightly older kernel so I could get my GUI again. I guess I have to wait for an even newer kernel to appear in Adept?

Thanks all for the help.

Thanks dude.

Re: ENVY asking for linux headers

Thank you for the help. Ran Envy under the newer kernel after following your advise on the other thread and I'm now back up and running with the Nvidia drivers.
