    how to reinstall network?

    Hi All,

    I accidentally uninstalled my "network" trying to uninstall and reinstall kppp. So I can not get to the Internet. Is there a way to mount my install D and reinstall my network?

    Many thanks,
    -T

    Is it a wired network? If so, you don't really need the network manager, just follow my instructions here.:

    If you want to reinstall network manager You can do that by uncommenting the lines in your sources.list file pertaining to the cdrom and install from your cd. If you need help doing that, post back.

      I thought I could figure it out on my own, but ....

        If you are referring to the LiveCD as an accessible "repository", that should still exist, assuming you didn't comment it out.

        Open a console and type:
        Code:
        sudo cat /etc/apt/sources.list
        Towards the top of the list you should see a line referencing cdrom. If it doesn't hava a # in front of it, that repository is still 'active.' If it does have a # in front, then it is commented, and not active. You'll have to edit the file (as root) in order to remove the # sign and make it active. Then you would, in a console, type:
        Code:
        sudo apt-get update
        As you don't have an internet connection, it will read the available packages from the CDROM (make sure you have the LiveCD in the drive before you issue the command).
        Windows no longer obstructs my view.

          How do I tell it to reinstall everything that is missing? "Apt-get install *" does not work

            Once you have the cd active as a repository, with the CD in your CD drive, issue the following two commands.

            Code:
            sudo apt-get update
            Then

            Code:
            sudo apt-get install network-manager-kde

                oh poop. I just noticed my eth0 is gone too (ifconfig). My Virtual Box console says it is there too.

                How do I do what they call in Windows an "in place reinstall"? It is easy to install, but I don not want to loose everything I have configured.

                Many thanks,
                -T

                  I don't think you edited the sources file correctly. Run

                  Code:
                  cat /etc/apt/sources.list
                  in a terminal and post the results here. Hang in there, we'll figure this out.

                  ifconfig only shows active interfaces, to see all interfaces run

                  Code:
                  ifconfig -a

                    "-a" worked. It is there. Thank you!

                    I got tired of all the hassling messages about what could not be found, so I make a backup copy of sources.list and then created this:
                    Code:
                    cat sources.list
deb cdrom:[Kubuntu 9.04 _Jaunty Jackalope_ - Release i386 (20090420.1)]/ jaunty main restricted
# See [url]http://help.ubuntu.com/community/UpgradeNotes[/url] for how to upgrade to
# newer versions of the distribution.

                      I do not mind reinstalling, as long as I do not wipe everything out

                        OK run update and install again, if it doesn't work this time, try
                        Code:
                        sudo apt-get install knetworkmanager

                          You can run the CD again to repair the install if all else fails. That's one of the options listed. What I'm thinking is, that the network manager may not be on the cd, but during the install process, Kubuntu establishes the connection and downloads it. I'm not sure, I thought it was on the CD.

                              I hate to repetitive, but if you follow my instructions in the howto I posted earlier, you would be connected by now. It's really not complicated.
