Ok, so the desktop packages are showing up- when you select them for Information, what does it show? I never installed Zorin Gnome Core files as if I wanted Zorin Core, I just installed Zorin OS Core.
Ok, I opened Synaptic on my end and compared packages. The “zorin-os-desktop” is the correct package for Core.
Odd, your first screenshot shows both Core and Lite- one should be highlighted as installed already.
ok. Install?
Go for it. Let’s see if broken packages are still held. When you mark it for installation, then click apply, it will give a pop up showing all the dependencies, then proceed.

I have never had Synaptic claim dependency problems AFTER allowing an installation.
Given any more thought to dual booting Zorin Core alongside of Zorin Lite?
EDIT: Hold on- are you installing from Synaptic or from Terminal?
GONNA GIVE IT UP

testing out with term to fix apt and it is ok. 66 REPLIES OH MY GOD! So what now? lets continue tommorow.
Don’t worry you are not into 3 digits yet 
Just keep coming across this thread in “Latest”, that all. Keep up the good work!
I was just wondering if I reinstalled Zorin OS Core i mean over lite and would it keep my data? I mean in the same drive in which Zorin OS Lite is, I want to install it there
It may, if during install you leave your existing home partition untouched. Then it would show up separately under “Other Locations” in Nautilus.
how to do that?
When installing with Something Else option, delete the old root partition but don’t delete the old home partition. It may be that you simply have to install over the old root, I forget, but basically as long as you leave the old home partition untouched, you will see it after you reinstall, albeit under Other Locations.
Ah. Pain.
Important thing is do not Format your Home partition if you decide on this course of action and want to keep your data.
GNOME WORKS FINALLY! but via ubuntu-session, Zorin Session is broken… Well in a not so crunchy crunchy way. Can’t see the point why Zorin Session doesn’t work. Ok. Thanks for your hardwork. Thanks to me for my hard work.
CONCLUSION: If you wan’t to get GNOME, go for installing Zorin OS Core as @carmar and @zabadabadoo said, Install with the something else option and delete the root but not the home partition. If you want it like me, try to install zorin-os-desktop and zorin-os-session from terminal and don’t leave yet! do a quick sudo dpkg --configure zorin-os-desktop and sudo dpkg --configure zorin-desktop-session. Then log out and try both Zorin OS Session and Zorin OS Wayland session. If that doesn’t work, just install ubuntu-session and log out and try Ubuntu and Ubuntu on Wayland. That should work. If it doesn’t, install Zorin OS Core like the above steps or just don’t do it. That was all for this topic, thanks!
