uninstalled bluetooth; now, no network anything anywhere; synaptic package manager won't recognize cdrom - tired of doing clean installs. should I go back to windows?

Asked by pjan

uninstalled bluetooth; now, no network anything anywhere;

synaptic package manager won't recognize cdrom so I can reinstall the network manager or network manager gnome -

tired of doing complete Ubuntu installs every time I uninstall something. If I can run it from the CD, and "clean install" it from the CD, why can't I retrieve it and re-install it from the cd?

should I go back to windows? (If I wrote code like this and sent instructions to my users like the Synaptic Package Manager not findng the cdrom with the disk I used to install Ubuntu, after following the instructions in "Help" file, I'd get fired and escorted from the building).

Got "apt-cdrom add" to work. Still can't get networking from the Ubuntu cdrom. If I boot from the Ubuntu cdrom I have networking. I'm on the same box using XP to type this so I must have networking available.

programming for 17 years on a unix box.

I would appreciate some help. All I want to do is recover my internet and network settings.

Maybe you could leave the files that are downloaded from the CDROM for networking ON the TARGET DISK SOMEWHERE JUST IN CASE ey?

Extremely disgusted with Ubuntu.

Removing bluetooth will also remove network manager, the software center warns of this before you commit. If you used synaptic then it may not have. You should be able to re-install it from the cd, just insert the cd and it will prompt you to start synaptic package manager, then you will want to install the network-manager-gnome package. I just tried to do this but only have a 32 bit disk so it would not load on my 64 bit os, so let me know if it works.

I just re-read your post and noticed that you did try the cd-rom method but it would not recognize it, strange. not quite sure what to tell you now, i'll look more into it.

Open a terminal and try this:

sudo ifconfig wlan0 up (or if you are using a wired network card: "sudo ifconfig eth0 up")
dhcpcd

then test to see whether the Internet is working, and if so reinstall whatever network GUI stuff you want.

Please, don't panic. In case you know the name of the uninstalled package, it's very likely that you have it stored in /var/cache/apt/archives, and you can install it the usual way.

If you can mount your CD, packages are there in one of the directories. I can't tell you where exactly, because just now I don't have one myself to browse it...

Good luck!

Please try from terminal:

sudo apt-cdrom add

the system ask you a password give your user password, you will not see nothing when you type it, then press enter

 apt-cdrom is used to add a new CDROM to APTs list of available sources.
       apt-cdrom takes care of determining the structure of the disc as well
       as correcting for several possible mis-burns and verifying the index
       files.

       It is necessary to use apt-cdrom to add CDs to the APT system, it
       cannot be done by hand. Furthermore each disk in a multi-cd set must be
       inserted and scanned separately to account for possible mis-burns.

Additionally, if you are new to Ubuntu, i recommend reading through the Ubuntu Manual, it's very informative:

network-manager-gnome was missing. Could not find it on CD anywhere. Booted to windows, downloaded it from packages.linux.com to flash drive (was a .deb file), rebooted linux, copied .deb, double clicked it, it installed (all dependencies satisfied).

Problem solved, no set up necessary, all parameters still available.

I would not have intentionally allowed it to be uninstalled. If it was in a warning list, I did not see it.

Maybe uninstalling bluetooth should not take network-manager-gnome with it. Would kind of assume OTHER things might need network-manager-gnome.

Just a thought from a rank amateur.

Thank you Xuacu Saturio - your post is what made me look for the .deb for network-manager-gnome.

To Pip and all -

Thanks for your advice - I didn't see the latest post until getting the connection re-established. You are right about the removal, I just couldn't find it in /var/cache/apt/archives or on the 10.04 LTS i386 disk.

Did find it on-line though.

Thanks again for such quick answers.
