Ubuntu hardy upgrade problems

I got hardy yesterday, and the upgrade wasn’t without problems. I’m posting my solutions here: hopefully they’ll help someone else.

Nvidia

First, Ubuntu wouldn’t let me upgrade, saying “Couldn’t calculate upgrade”. A peek at the logs (at /var/log/dist_upgrade/) revealed that this was because of nvidia-glx. It needed to be removed (because there is now a nvidia-glx-new), but it was in the removal blacklist. So I thought I’d do this manually. I removed nvidia-glx and installed nvidia-glx-new with apt, and then tried upgrading again.
I consider this a bug in the upgrade system. The installer should at least tell me that this might be the issue, and that I should consider changing my drivers, because if I hadn’t known about the existence of nvidia-glx-new, the log alone would have been of no use.

Ok, having done that I tried dist-upgrade’ing again. This time it looked like it was going to work. But then it threw up errors about nvidia-glx-new, and every single xorg package. I tried reinstalling nvidia-glx-new, but dpkg didn’t let me (I kept getting “subprocess post-removal script returned error exit status 2”). Google led me to this:

sudo dpkg-divert --remove /usr/X11R6/lib/libGL.so.1
sudo dpkg-divert --remove /usr/X11R6/lib/libGL.so.1.2
sudo dpkg-divert --remove /usr/lib/xorg/modules/libGLcore.so

However dpkg-divert gave me “No such file or directory” for each of the libgGL’s. After some headscratching, I realized the reason was that there was no ‘lib’ directory in ‘/usr/X11R6’. So a ‘mkdir /usr/X11R6/lib’ and then dpkg-divert –remove fixed the problem.
I still don’t understand how this happened in the first place – I’m just happy I got it to work.

Terminal Fonts

After hardy was installed I noticed that my Terminal had stopped antialiasing its fonts. Here’s the fix:

cd /etc/fonts/conf.d
sudo rm 10-hinting-medium.conf
sudo rm 10-no-sub-pixel.conf
sudo ln -s ../conf.avail/10-hinting-full.conf
sudo ln -s ../conf.avail/10-sub-pixel-rgb.conf


Firefox

Now my one remaining gripe is with Firefox. ff3b5 is highly unstable for me. I used Beta 4 up until now, and that worked just great. beta 5 has crashed on me 4 times just while writing this blog post! (although that’s an extreme case.. it isn’t that bad normally).
However, I may have found a solution. I’m beginning to think its firebug that’s causing the crashes, but I’m not sure yet. Any other ideas?
