Yep something is off alright. Please read my original reply which you quoted back.
I am returning your pic back with a green arrow and a red arrow.
Notice You are still using software updater (the green arrow.
Furthermore Synaptic is the next tab (The red arrow.)

It's wonderful to see this forum open but I notice a second updater window open as well.
Perhaps do all your updates first then close all except synaptic.

Run in terminal
sudo nano /etc/apt/sources.list
Move curser down using arrow key
Copy paste save & exit
http://ppa.launchpad.net/sunab/sigil-git/ubuntu/
Run sudo apt-get update
sudo apt-get install <package>

Larry, thanks. I really hope I'm not doing something embarrasingly wrong, but when I click on "Repositories" I do not get the screen you showed (attachment 101). I get this screen (screenshot 102). So when I click on "Repositories" instead of getting the "Repositories" window I am getting the "Software and Updates" window.

I wasn't updating anything. (I don't know how!) It's like I'm missing the Repositories window. And the second update window was just what Xubuntu sends me to update the OS. I just hadn't downloaded it yet. And I closed out of everything but Synaptic and tried the whole process over again and got the exact same results.

Eddy, thanks. So this will get me Sigil from the terminal? I just need a little clarification though. I get this part:

Run in terminal
sudo nano /etc/apt/sources.list

But then this:

Move curser down using arrow key
Copy paste save & exit
http://ppa.launchpad.net/sunab/sigil-git/ubuntu/

I'm not so sure about. So I move the curser down to http://ppa.launchpad.net/sunab/sigil-git/ubuntu/. Right? Then I copy it. Okay. But where am I pasting it? And how am I exiting?

Lastly:

Run sudo apt-get update
sudo apt-get install <package>

Are these two separate commands?

Thanks.

Nice video but it's already in your sources.list, it would be nicer if you would the the OP how to add a repo using same technique.

Ok I did notice that there is a radio icon that says "NEW"
But also in order for the new repo to be available you have to select "Reload".

I have the same version of the synaptic package manager as you (nice Cure music btw). I did exactly what you did, but when I left-click on "Repositories" in the drop-down menu, the "Software and Updates" window opens instead of a "Repositories" window. On the tabs (of the "Software and Updates" window)though when I click on the "other software" tab I get this (see screenshot, which I maximized), which is similar to your "Repositories" screen but not the same. I don't know what's going on, but this is where it stands.

Do you think that because you don't have canniocal checked in sources.list that that is why you don' get your dependencies met?

Eddy, I'm so new I don't know what should be chekced or unchecked, and I didn't even know that I didn't have my dependencies met. But I mean, this is the synaptic package manager. I had to click on several things to get to that software & updates screen, are you supposed to have to do that to use synaptic package manager? (It seems pretty complicated if you are, and it would seem there would be some kind of notification saying you should to it.) Thanks.

Hi there

Let's try another way. Download an unofficial debian package.
You can then install it with either your GUI or follow instructions on page.
Then mark this thread solved.
Please accept my apology for getting you to try the gui.

Thanks Larry. I actually saw that page a long time ago but didn't know what to do with it. I won't be on the computer that needs Sigil till tomorrow, but when I get on I'll give it a shot.

Tried to do it from the command line. No luck. (See screenshot 41). Was going to download the file (Sigil-0.7.4-Linux_x86.deb) and then try to install it from the Synaptic Package Manager, but figured it would be better to install it from the terminal and ask you about it first.

Unless you downloaded the file to your Desktop, you're in the wrong directory. You should be in Downloads directory.
You can also go to Downloads in filemanager, locate the .deb file, right-click on it & select "Open With Gdebi".
Can you open a terminal & post the output of
http://ubuntuhandbook.org/index.php/...buntu-via-ppa/

Hey EDDY. Downloaded

Sigil-0.7.2-Linux_x86.deb

Found the file in the File Manager and right clicked on it. The options for opening were:


-open in ubuntu software center
-open with Archive Manager
-open with other application

I chose "other application" but there was no Gdebi in it.

Here's the results of the command you asked for:
