Ubuntu upgrade from 71.0 to 8.04 Hardy Heron

I carried out the upgrade from Systems -> Adminsitration -> Update Manager as per the Instructionns at Upgrading to Ubuntu 8.04 LTS
Remember to update current version before installing 8.04.
Current installation updates were 300 MB and 8.04 installation changes were 800 MB. First problem I faced during installation was hang during generating locale.

Generating locales... en_AU.UTF-8...

There are different solutions for this issue. Refer to [ubuntu] Hardy 8.04 update freezes on generating locales - Ubuntu Forums
What worked for me is, starting in recovery mode with 7.10 default kernel 2.6.22.15 , select the option open up shell as root and then run

dpkg --configure -a

And then whenever generating locales comes up kill the localegen processes using kill -9 After these installation used to abort with following error

dpkg: too many errors, stopping dpkg: ../../src/packages.c:251: process_queue: Assertion `!queuelen' failed.

I repeated running dpkg after rebooting in 8.04 default kernel. This time locale generation worked fine but there were lot of errors with gnome configuration due to which dpkg aborted.
Next I logged in using failsafe mode in 8.04 default kernel. One can switch to failsafe mode by clicking on options available at left hand corner bottom on the login screen. Then select sessions option and popup will come up with session options. Select failsafe GNOME session. After logging in again run above dpkg comman in a terminal.

sudo dpkg --configure -a

After this rebooted the machine and it looked like things have fallen to place.

First impressions - Its hardly couple of hours since I started using Hardy Heron

• Looks like wireless support has improved a lot. I could see the available networks from network icon on right hand side corner without any configuration! That was not there before.
• Default background looks good and fits the release theme.
• Looks like firfox 3.0.1 has issue with address text box ... It does not get updated and does not take whatever typed in . Only way I can visit the sites is through the bookmarks !
• Not sure if there was a crash reporting facility earlier ...
• Brasero does the disc burning.
• Boot takes more time than 7.10

Update Aug 3rd
If you are on a AMD 64 machine fixing flash player follow the instructions at
Flash 9 install script for AMD64 (nspluginwrapper)
For the last instruction, creating the link in plugins directory of firefox make sure you are using directory name based on ur release of firefox. (such as firefox-3.0.1

Correction - firefox 3.0.1 address text box might have occured as I was in the middle of plugin installation. It seems to be working fine now.
