I recently tried upgrade from 9.04 to 9.10 on my netbook, but something went wrong, and X session hang up. After reboot I still can log to system, but Gnome is rather broken.
I found that I can issue command "sudo do-release-upgrade" to continue upgrade, but it tries to do upgrade from 9.10 to 10.04, even I have "jaunty" in /etc/apt/sources.list.
I guess thats because some information in system has 9.10 in version, like "lsb_release -a" gives "Release: 9.10"
My question is: Where I should change release information, so "sudo do-release-upgrade" can do upgrade 9.04 -> 9.10, not 9.10 -> 10.4
I know how to copy /home dir and reinstall system with preservation of this dir, I'm just curios if there is way to rescue sys by working with apt-get, aptitude, and dpkg. I'm sure that all changes were made only by these tools so maybe there is way to fix it. And, yes I know that 9.10 is a little bit outdated but it is still supported and I use it because of software compatibility.
