    Daemmon,

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

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

    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

    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…

    Maria,

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

  • Maria Jun 8, 2006 @ 7:15

    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

    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”?

  • LinuxTitli Jun 2, 2006 @ 20:18

    Thanks, I had updated the post 🙂

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

    Marc,

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

    Appreciate your post and feedback.

    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.
