[Ubuntu] grub2

[Bug 402154] Re: grub2 Windows 7 fails to start.

The grub2 in the jaunty repos is grub2_1.96+20080724-12ubuntu2_i386.deb

not sure if thats my problem

[powdarrmonkey]

Ah, yes. That's certainly not going to help

It's a karmic installation, right? Once you've chrooted into it you should be able to apt-get dist-upgrade to get grub2_1.96+20090725 and then reinstall it as before.

If it's a jaunty installation (ignore the rescue cd, you're just using that as a way to chroot) you'll have to add mixed repositories, pin them to jaunty, and pull in the karmic grub2 package. I'll walk you through that if you have.


Edit: I just thought, I would actually do an apt-get update and then apt-get install grub2, which should just upgrade grub2, not everything else.

Its not karmic. just jaunty with grub2 upgraded.

grub says its up-to-date so if you could talk me through how to get the karmic version Ill give that a whirl

[powdarrmonkey]

Oh sorry, must have mis-read. Anywho,

1. Add karmic repositories to your apt sources (use a local mirror)
2. Pin the default to be jaunty packages:

/etc/apt/apt.conf:

APT::Default-Release "jaunty";

3. apt-get update, apt-get install -d -t karmic grub2
4. Check the correct version was downloaded, then drop the -d to install it

Im a bit dumb this afternoon...

I dont have an apt.conf, ive got a apt.conf.d folder though.

Also, what are the karmic repository lines to add to sources.list

This is what Ive got for jaunty, do I just add the same but change it to karmic?

deb http://ftp.iinet.net.au/pub/ubuntu/ jaunty main restricted
deb-src http://ftp.iinet.net.au/pub/ubuntu/ jaunty main multiverse universe #Added by software-properties

[powdarrmonkey]

Create it, and yes.

[RabbieBurns]

apt-get update seems to have added the karmic

Managed to sort it. Found the deb of the latest build of grub2, and installed it manually. It all works now

Aha, I was just looking for this thread. Excellent

Do you reckon I should take the karmic out my sources.list now? Update manager keeps prompting me to update a whole heap of stuff... Or should I keep it in so that I will receive updated to firefox which Ive installed from the karmic source?

The default that you've put in /etc/apt/apt.conf should stop that happening... it might be a ubuntuism, you might have to put it into a new config file in /etc/apt/conf.d.

Finally got round to upgrading from the RC to the RTM yesterday. Went for a complete reformat/reinstall.

Grub2 went on straight away no problems.

Heres the link I used the last time, I forgot to post it here the last time, but here it is in case anyone from google or anything is looking for answers.
