I don't know why, but every time i try to apt-get install something, the same error happens, just like this:

Code:

$ sudo apt-get install gcc

Have you tried removing and then getting the medibuntu pubkey again?

I've been having this same problem after upgrading to Ubuntu 11.04. I get this on every package I get, not just one.

Find what package is causing the issue, in this case medibuntu-keyring, go into synaptic and remove it completely, then re-install it.

dpkg is the heart of your package management system. If there is an error it is not going to work until you correct it.

Man pages are your friend if you want more information on the package management system.

Code:

man dpkg

is a great place to start.

This link is real good too;

Yes I know it is from Debian. So is Ubuntu.

I believe mine is stemming from Samba4. It was part of the upgrade and failed. Now, it seems that I can't remove or install much. Where is synaptic? I've not heard this term yet (i'm still a newbie).

System>Administration>Synaptic is where you will find synaptic. Wonderful graphic front end for package management.

I reported a bug and a bunch of other people did too. Now, I'm getting lots o e-mails of poeple having this same problem. One said to simply uninstall Samba4, but when I try, I get an error and it never completes.

Try this;

Code:

sudo apt-get -f install

That may help. Certainly won't hurt.

When you find Synaptic go down to the bottom left pane and click on Custom Filters, then in the top left pane click on Broken and see if anything is listed there. Click on it and mark it for Complete Removal. Then up the top click apply and go from there. If there are any errors post them here and we can help you through it.

You could also try this from the terminal:

Code:

sudo apt-get install -f
sudo dpkg --configure -a
sudo apt-get update
sudo apt-get dist-upgrade
