upgrading from 8.10 to 9.04

[tamobe]

I'm currently running Ubuntu 8.10 and would like to upgrade to 9.04 but the update manager has never given me the option of upgrading. I just tried switching the Software Source but still the Update Manager simply says "system up-to-date". Any suggestions?

Open a terminal (Applications>Accessories>Terminal) and type
update-manager -c After that it should say something at the top of the window. Hope that helps! :P

If you're not terminal shy, use the following commands



# Update your system to the latest and greatest packages
sudo aptitude update && sudo aptitude -s safe-upgrade
# If you are happy with the changes
sudo aptitude -y safe-upgrade
# Start the upgrade process
sudo aptitude install update-manager-core
sudo do-release-upgrade

thanks so much for your help! that worked.

my other question is at the end of the install/upgrade the terminal asked the following:

Setting up gdm (2.20.10-0ubuntu2) ...
Installing new version of config file /etc/gdm/Init/Default ...

Configuration file `/etc/gdm/gdm.conf'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : background this process to examine the situation
The default action is to keep your current version.
*** gdm.conf (Y/I/N/O/D/Z) [default=N] ? z
Type `exit' when you're done.

what does this mean?

I'm having the same problem, only the commands entered into terminal did not work. Anything else for me to try?

hey Thedosius,

In the terminal did you try entering this code (you can just copy and paste it):
sudo aptitude update && sudo aptitude -s safe-upgrade

and then when that's done try the next one (again you can just copy and paste):
sudo aptitude -y safe-upgrade

and then when that's done this one finally (again you can just copy and paste):
sudo aptitude install update-manager-core
sudo do-release-upgrade
