You are actually incorrect in the command you posted to upgrade from breezy to dapper.
‘gksudo update-manager’ will open up update-manager, but not prompt you to update to a newer major release. This default was requested by Mark Shuttleworth. To display the “new distro available” upgrade option, try this command:
‘gksudo update-manager -d’
Also, this is the “suggested” way to upgrade from breezy to dapper and is what should be first.

Thanks, I had updated the post

However, method # 1, worked very well for me.

I upgraded to Ubuntu 6 (”Dapper Drake”) from Ubuntu 5 (”Breezy Badger”, which I was already pleased with) and was pleasantly surprised to find that my system is much more responsive than with Breezy. Firefox seems especially snappier. I really like the new GNOME deskbar applet too.

Also, in your tag line, I think you mean “comprehensive” rather than “compressive”?

Marc,

They have optimized the kernel so we will get nice speed and thanks for pointing out typo

Appreciate your post and feedback.

please help…. i tried method # 1 and this is what i get…
tgb@Extra:~$ sudo apt-get update
Reading package lists… Done
tgb@Extra:~$ sudo apt-get -y dist-upgrade
Reading package lists… Done
Building dependency tree… Done
Calculating upgrade… Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
tgb@Extra:~$ sudo update-manager -d

why is that so?

i also tried method #2 but it only says that my system is up-to-date when in fact i only have Breezy Badger version.

please help.

many thanks,

maria

Maria,

Did you modified the your /etc/apt/sources.list file and replace all word that read as breezy to dapper?

Better yet, did you remove the # before all of the http:// lines? if you don;t then apt will not have a clue that it should be looking at the interent to get the updates…

Hello,
I am trying to upgrade to dapper from breezy. I tried method #2 and got:

bash: gksudo: command not found

How do install gksudo? Your post seems to imply that this should be installed by default so I am also wondering why it isn’t in my system already.

Thanks

Daemmon,

gksudo is part of Gnome desktop and it should be installed. Try any one of the following:
kdesu update-manager â€“d

Or to install gksudo type the following command:
sudo apt-get install gksu
