I just did system upgrade form 9.10 to 10.04 using alternate CD described here: https://help.ubuntu.com/community/LucidUpgrades#Upgrading%20Using%20the%20Alternate%20CD/DVD - I did it this way because I have limited Internet access and I can't afford to do it by downloading all packages from repositories. And btw. this method is using default Ubuntu distribution upgrade application.
After reboot, grub and white Ubuntu logo on black screen, boot process stops on blank screen. When I try run system in recovery mode I have this message:
init: plymouth main process (449) killed by SEGV signal
This bug is known, but I have not found solution: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/571258
I have also tried removing "quiet splash" from boot parameters, but it doesn't helped at all. But I received additional info: "mountall: Disconnected from Plymouth" prior to this error.
Any idea how to fix boot process so I can use system? Thanks, Damian.
