I have been following the upgrade path with Ubuntu with very problems since 9.04 or 9.10 (I can't remember which). In general, the upgrade path has been a good experience for me.
I used Remastersys to backup my 10.04 installation. I installed my backup on an empty partition. I used the backup partition for a few days and all worked properly. I then did the update using the Update Manager in 10.04. All went smoothly.
Then I rebooted ...
the following on screen messages:
- waiting for network configuration ...
- waiting up to 60 more seconds for network configuration
- booting system without full network configuration
The boot completed and, as far as I could tell, the network worked.
For some strange reason 12.04 didn't find my existing swap partition. It made a new swap partition. I removed the new swap and edited fstab to redirect Ubuntu to the old swap partition.
After a while, with my box happily idling, a warning popped up asking me to send a report of the problem. I clicked the required button. After much soul searching, Ubuntu failed to send the report. I attempted to remove apport using synaptic package manager. This is when I noticed a problem with synaptic. It returned an error due to a problem with emacs. I purged emacs which fixed Synaptic. Then I removed apport.
I rebooted to see what other problems I might have fixed or caused. The same network error shows up and I am unable to find the cause of the error. This is very frustrating.
