again, gimp is not part of mint 19.3. You can say whatever you want (if it was a bug, agree with anyone or think anything) it will not work. Just because it is removed. If you wish you can create a bug report, but I'm afraid that will be refused/ignored.
If you want to make it work just use the link I posted. That will solve this issue. Or reinstall 19.2. Or use Kali if that is acceptable for you (actually Kali is not meant to run gimp, but it looks irrelevant now).
From the other hand your original post contains a different error message (libgegl related). Probably it is the root cause I don't know, but you would need to get "gimp not found" on mint 19.3, so that environment is not a clean mint 19.3.

It is a bug as it is listed in the software manager which does not work.

I explained I loaded GIMP 4.10 from the GIMP site maybe you did not read that.

You make an unfounded comment about Kali why do you think it is not meant to run gimp. You need it for editing websites and Kali is all about websites. Next you will say it is not meant to load libreoffice or thunderbird.

So they are downloading unclean mint that is a bug too.

As I tried to explain your system is not clean, somehow the package management system looks corrupted. It should be fixed.
That means everything reported/displayed by your software management system is unreliable. This is an internal problem, not a bug (as long as it is not fixed).

if you were really interested: kali is a special distro for penetration testing. Kali is not about websites, but penetration testing. Not meant to use as a general distro and also not meant to do graphical work or editing websites.
But as I mentioned it looks not so important now. If you like it, use it.

According to The Register GIMP hasn't been removed from the repos, it's just not in the default install.

In that case it makes more sense.

I'm on 19.3 and apt finds gimp. Further Mint's gui software manager finds gimp. Suspect the issue is local to your machine.

Then why does the software manager say not available? If it was there it should be able to be loaded from the software manager.

It actually still says that after I loaded 4.10 from the web as well it is now in the menu but hasn't told the software manager it is been installed which usually happens.

Sudo apt install gnome still says it cannot be installed and typing gnome does not find it.

Has anyone been able to install gnome from the package manager with 19.3 to check this out?

Your system was probably not upgraded properly.

What output doesgive?

I had this from Linuxmint forum and have had a good answer.

Great that worked and it gave 2.8 Gimp the one I prefer. I loaded 2.10 from the Gimp site.

It also fixed the software manager that had said not available now it has Gimp 2.8

In the manager I have two gimps now the 2.8 and
Flatpak 2.10 which fetches up the latest version

I have run out of machines to do a fresh install on with another download to see if mine was actually corrupted.

In the forum they also all seem to have Gimp on 19.3 as well.

No chance now as I fixed it with the sudo apt update

I have yet to find if the iso download was corrupted or if they have changed the server

you sure?
You can still run the command and show us the output; the '-s' means 'simulation', so there's zero risk involved.
I agree with others - something might be messed up in your package management still.

Of course I fixed it
