I think I noobed...

So I reverted to Firefox2 through a process of temporarilly converting to the Hardy repos temporarilly. That went fine.

Here's the deal. I went to remove FF3 (because I hate it, it's a buggy/resource-hogging piece of ****, I loved FF2 though) and well...I'll let this do the talking:

Code:

laptop:~$ sudo apt-get autoremove firefox-3.0

Out of habit I just typed Y and hit enter without reading. *facepalm*

So did I just delete my kernel or an essential part of it, and if so, what's done to get it back?

It's common for Ubuntu to keep a handful of old kernels around just in case something goes wrong while running newer ones and you need to go back. In the absence of evidence to the contrary, I suspect that you're probably safe.

Are you experiencing anything bad or were you just concerned by what the terminal told you?

**Locutus_of_Borg** · May 3rd, 2009

does the command 'uname -r' output "2.6.27-7-generic"?

if so, you will need to reinstall your headers by means of apt-get install linux-headers-2.6.27-7-generic

if not, it is safe to ignore assuming you do not intend to use the old kernel or have need for the kernel headers which is used for such things as compiling source, etc.
