(SOLVED) echo Error linux-image-unsigned-4.15.0-30

Last night, I managed to utterly demolish my Zorin 12.4 Core O.S.
No idea how I did it, don't ask.

I did a wipe and reload, clean install, wipe drive, 12.4 LITE.
That sucked, by the way. Thankfully l I had MOST things backed up.
Today, I cannot install or uninstall anything, now. I keep getting an error:

Code:

dpkg: error processing package linux-image-unsigned-4.15.0-30-generic (--configure):

I looked up a lot of tutorials on it, I installed the headers using Synaptic after it said it could not find them, Yet, nothing I do seems to fix this problem.
I tried dpkg force remove.


I really would prefer to NOT wipe and reload again...

Code:

EDIT:

And just marked this as solved...
I literally spent Two hours on this. I could list out all the bash in three very long posts.
In the end, I gut frustrated and opened Synaptic and searched "4.15.0-30.32"- It came up with a kernel and modules. I marked for complete removal, hit apply...

...and it fixed it.

FIGURES!

Just found an interesting post here:

http://ubuntuhandbook.org/index.php/201 ... nt-3665387

It's worth reading.

Well, I figured out how I destroyed my copy of Zorin 12.4 Core... I had tried to workaround Nautilus.
I hate Nautilus more and more as time goes by....
Nautlius kept Hijacking my settings. What I did to try to stop it resulted in a portion of Python-Nautilus being uninstalled.

Just Like Microsoft. Embed it and Integrate it then take over control.

I wiped and reloaded using Zorin 12.4 Lite and then I had the errors above.

After that got resolved... I started having some very strange things happen.
Thunar slowed to a crawl. I tried many different fixes... Until I noticed that a folder for Audacious got installed in the Filesystem folder - right before bin folder, it was sitting there bold as you please.
I removed it, suddenly thunar was normal again.

Then, when I logged out and back in, I noticed that the chooser was set to Gnome Flashback, not XFCE.
I do not have gnome flashback installed. At All.

I USED to have it installed on the Zorin 12.4 Core but I never installed it on this 12.4 Lite. I had uninstalled it from Core after a long while, though. How did Gnome Flashback end up on this?
I uninstalled it using Synaptic.

Well just been searching to find out why Linux Kernels no longer signed and stumbled upon this interesting article. Sorry if it is off track:

Learning is Never off track.
Not only might I understand the problem more, may be able to prevent it in future.

I admit, it did blow my mind that I could do it with Synaptic, but not terminal. Clearly, I do not understand how to use the terminal anywhere near well enough.
