AMD64 Error

Look at your repository list for duplicate entries.

To see your repository list, open Adept Package Manager, select View, Manage Repositories. You may have to scroll down to see them all.

The following are duplicate entries, though they don't look like it:
deb http://your.favorite.distro.com/distro edgy main restricted universe
deb http://your.favorite.distro.com/distro edgy universe multiverse

They are duplicates because they have the same URL and Distribution and at least one of the Components of one entry is a component of another entry.

The following are NOT duplicate entries:
deb http://your.favorite.distro.com/distro edgy main restricted
deb http://your.favorite.distro.com/distro edgy universe multiverse

If you find a duplicate entry, correct it.

Post back here with what you found and if you solved the problem.

P.S. It would make sense if EasyUbuntu grepped sources.list for repositories either already installed or duplicated and Did The Right Thing(TM) based on what it found.

After installing Adept Package Manager, upon execution I receive this message:

Could not launch menu item
Failed to execute child process "kdesu" (No such file or directory)

Ah. I'm sorry. I gave you the instructions assuming you are using the KDE desktop (i.e., Kubuntu), because that's what I use. You are using Synaptic so you must be using GNOME, and that should have dawned on me.

I think you may have stumbled across a dependency bug in Adept, because it should depend on the library containing the kdesu command. Fortunately, you can use either Synamptic or Adept to get to the same result, because they both read the exact same file (/etc/apt/source.list). Myself, I like adept better than synaptic, but that's just my personal preference.

Here are three alternative methods to review your repository list:

1. If you want to use Adept, edit your Adept menu item thusly:

     gksu adept_manager

and then fire it off. (It's also possible to install kde-base, which provides kdesu, but there's no need to drag in with it all the KDE dependencies just to look at your repository list.)

2. If you want to use Synaptic, it also has a method to manage repositories, but I can't remember where that is. (Preferences, maybe?) If you like synaptic just fine, you can uninstall Adept.

3. You can also open up your favorite text editor and read the sources.list file directly. You'll need to have root privileges to edit it. ("sudo your-favorite-editor") Again, you want to read "/etc/apt/sources.list". I think that EasyUbuntu might add a repository list as a file under /etc/apt/sources.list.d, or some such directory. Poke around (that's a technical term we use here in Texas) in the /etc/apt directory and look at any sources lists or repository listings. (The /etc/apt directory is a place to which you will return often, so you just as well learn your way around.)

I didn't mean to have sent you out on a snipe hunt. I hope this will get you back on the right track.

Report back how it turns out.
