Unable to boot 8.04 Alpha 3 Server install on laptop

"Unable to boot - please use a kernel appropriate for your CPU"
→ which version of install CD do you use?

I used the Server install i386 downloaded today (ISO image MD5SUM checked as 18b9db3935b2910e4afdb9816cfd2e0b hardy-server-i386.iso).

Try to wait two days to release of Alpha 4 - there will be newer kernel (2.6.24-rc8). Maybe it will help...

The same happens with Alpha 4, server install. Should I open a new bug, or perhaps add a point to bug 151942 and let them decide if it's the same problem?

I have the same problem with Alpha 4 too.

I'm sorry for double-post.

Jeronimo, I find that the fix of bug 151942 works here too. You have to boot the server install CD and choose "Rescue a broken system". When you get the prompt, run "apt-get install linux-generic" to install the generic kernel. Reboot and choose the new kernel in GRUB.

Vojtěch, thanks.

Same problem with alpha 5 on a thinkpad X40 with the model M CPU.
Just installed Hardy Heron Alpha 5 server i386, and it decides to install a kernel that doesn't run.

Same problem with beta server on VirtualBox

Confirming same problem on VirtualBox 1.5.6 with 8.04 Beta

Confirming same problem on VirtualBox 1.5.6 with 8.04 Beta.

Using x64 version of VirtualBox

The same problem with Ubuntu 8.04 LTS 32b Server.

Mac OS 10.5.2, Parallels Desktop Build 3188.

I have the same problem with my Thinkpad T40 running the final version of Ubuntu 8.04 server. The fix with running "Rescue a broken system" and installing linux-generic worked for me as well - but this is really a show stopper.

Hello i have the same problem with different systems (laptops, desktops).
With the fix with running "Rescue a broken system" and installing linux-generic it works .

Does the same for me on Parallels 3 on my Intel Macbook. No problem with the other 32-bit editions of [U|K|X]buntu nor JeOS nor Studio.

That's really fucking professional, guys. An LTS release for the /server/ that evidently wasn't tested enough. Shuttleworth should have given you a few more weeks like he did for 6.06.

Seems quite pointless to post in this thread, I don't think anyone is actually reading this, since there are no follow-up questions or anything. It's even marked as "Solved" by someone, whoever did that. It's obviosuly not solved. I think we all need to whine in bug #151942 for this.

Same problem with Ubuntu 8.04 LTS Server Final Release on VirtualBox 1.6

Same problem with Ubuntu 8.04 LTS Server Final Release on VirtualBox 1.6.

When using sun's virtual box, you can enable PAE/NX in the settings menu. It can be found in the Advanced tab of the General settings. This solves the problem for me.

NikiVanCleemput: How did you do that from the ubuntu server installation? Or are you talking about something else here?

Sorry, I wasn't very clear here.

It's nothing you can change in Ubuntu server, you must change the settings inside VirtualBox(check screenshot) http://tallytalent.com/virtualboxpae.JPG

I Got the ubuntu OS CD. After installing on VirtualBox , I got the problem like--- The kernel requires the following features not present on the CPU
0:6...

I try above solution posted here to enable PAE/NX.
and now it is working.

** The Advance option is available when your virtual OS is Poweroff. Select the OS installed on your virtualBox .First go to setting -->> General-->> Advance.

Here is the PAE/NX.

Many Thanks !

No PAE/NK option available in VirtualBox 1.5.6 advanced options tab.

Seems like the solution provided by NikiVanCleemput applies to VirtualBox 1.6

On my Ubuntu 8.04 laptop, Synaptic does only presents VirtualBox 1.5.6, no upgrade to 1.6 available with my current sources.list.

Is there an official Ubuntu repository I should add to my sources.list to get the latest VirtualBox version or does that mean I should consider an other way for upgrading ?

ok, I have upgraded from the binary for Ubuntu 8.04 x86 provided by www.virtualbox.org (the non OSE version though).

I checked the PAE/NK option (now available in this version) as mentioned above and everything works fine !

Very fine , we always try to upgrade from previous version.

You can use server installation CD to boot into rescue mode.
After mount the root partition of installed harddisk and get the # prompt, run this command "apt-get install linux-virtual".

This will help you get the linux kernel customized for VM environment.
You might need to run this command if installation not success - "apt-get build-dep linux-virtual".

Grub menu won't be changed in some case so you have to edit /boot/grub/menu.lst to boot with the virtual customized kernel.

Same problem with Ubuntu Server 8.04 i386 running on Virtual Box 2.0.2

The kernel requires the following features not present on the CPU
0:6
Unable to boot - please use a kernel appropriate for your CPU

Solution :

Power off Virtual Machine
Click Machine -> Settings -> General -> Advanced
Check Enable PAE/NX
Click OK
Start Virtual Machine

Thanks All for the help :)

i've a Packard Bell EasyNote and if i want to do that trick and come at that shell thing and i type: "apt-get install linux-generic" and do enter there is a message that apt-get is not existing like a command :s.
Please help me!
