Ubuntu 11.04 won't boot


Hi,

I recently upgrade to Ubuntu 11.04 and I recently started getting a problem where ubuntu won't boot on my laptop. On the boot screen all I get is :

/etc/rc2.d/599acpi-support: line7 : /usr/share/acpi-support/power-funcs: No such file or directory

and the screen will stay here.

I also have windows seven installed on a seperate partition on the same laptop and it works just fine.

Any ideas? Thanks in advance for the help.

From the error message it appears you do not have ACPI support installed.

Upgrades are pron to failure. You may have to do a clean install, if you can't get it to boot. If you want to know what ACPI is, see this link. -->http://en.wikipedia.org/wiki/Acpi

Thanks for the reply. I have some important files on my ubuntu partition that I don't want to loose. Would it be possible to create an Ubuntu 11.04 CD, boot from that and perform some sort of repair?

You need to search for the bin or script /usr/share/acpi-support/power-funcs ,
it may be inside /etc or /lib/lsb/ now or from the DL site of Ubuntu :
http://packages.ubuntu.com/natty/acpi-support .
The file list is quite large , especially for toshiba and asus .

If you want a rescue CD you can use the 700MB LiveCDs of the various Ubuntus.

It may be the only thing that is hanging your boot , but there may be probably more to come after wards.

If the old kernel worked well with your HW you should keep it .
ACPI can be configured as several modules (button , ac , thermal ...) or inside the kernel .
You don't know if the configuration of the new kernel had changed ,
if you do not diff /boot/config`uname -r`* .

If you have files to rescue, any live CD will allow you access to the files. If the files are on your /home/youruser/ and this is on a separate partition, you can format your root partition ( only ) and re-install.

Only other thing I can suggest, is most systems allow you to pass the kernel boot parameters. noacpi is one of them. That may allow you to boot. You need to do that from a grub2 screen.

Using the install CD, I was able to install the missing files however ubuntu still won't boot up. The only other error that I can see on the startup screen is:

[error] (EAI 3) Temporary failure in name resolution: Failed to resolve server name for 111.111.111.111 (check DNS) or specify an explicit server name

What does this error mean, and could this be what's preventing my system from starting up? (The other error I was recieving is now gone after installing the missing files).

Problem Solved!!! I remembered that I added some start-up scripts to control my screen brightness just before this problem started happening, I removed the scripts and now ubuntu boots just fine. Thanks for your input everyone.
