I'm not a fan of flatpak, I'll wait for Gimp 3 to get pushed down via ppa. Curious when that will happen. I would try an appimage however.

Gotta laugh at the experimenting

Apparently Gimp 2.3 is not a stable version.
The stable version is Gimp 2.4 and the devs are about halfway there.

I don't like flatpak either (nor snap), it something I found
As universal I like appimage, I rather go with a downloadable .deb or directly with a PPA, but appimages are quite nice IMHO.
but snap and flatpak

I did install this flatpak 2.99.10, there is no theme, it's slow to start (3 seconds before to see the nag screen every first start) and it's freak'in huge compared to a .deb/PPA or even appimage.

NOTE: Exclusive Windows and macOS users, if you're are reading this, it's just a Linux discussion about how we like our software installed (it would be something similar like an .exe or a .dmg on your system)

Um... we are at GIMP 2.10

Anyway, GIMP kept this notation that I learned in the 90s/2K that I love as it has a true meaning.
Every odd number after the first period means unstable/test version like 2.5 or 2.9 etc, and every even number after the period means stable like 2.10 or 2.8 etc, or even 2.10.30 which is the latest stable, there is only even number after the first period on every GIMP stable version

Thanks Patrice your right. I got confused but why is that page still up anyway?
The latest Gimp versions work perfectly on Ubuntu 22.04 but almost all plugins and scripts don't work. Don't throw away your 20.04 systems and the appimages that support Python 2.7 I say.

At the end of the day Gimp is just a 2D app in an increasingly 3D World. That doesn't mean a lot of Gimp images don't look 3D but can you revolve around and inspect them in 3 dimensions? No.

I will post any AppImages I make here.

This was made from the Gimp deb file for the next LTS Ubuntu version. Make executable and it's good to go.
Sorry about the delay, I tried to get it on GitHub but the platform doesn't like big files

My testing is this works on Ubuntu 20.04 and 22.04 but scripts only in 22.04 and no python.

BTW scripts and plug-ins are in .config/GIMP/2.10/
The same as the installed Gimp. That's because this is the installed Gimp in an appimage

That is a monster, 375 MB Does this one have python support ?

No python support in LTS22.04 or 20.04. I don't know if this is the OS or Gimp or Both

Thanks Tas for your Gimp 2.10.30 appimage. It works fine here in Linux Mint 20.3, which is based on ubunto 20.04 LTS.

My python scripts work here because I already have gimp-python installed and python2 enabled. That's how I have it set up for my ppa version of Gimp 2.10.30.

Edit: oops, I spoke too soon. G'mic doesn't work in this appimage.

Thanks for testing racer-x.
I'm glad python plugins are working for you because they don't for me
On the later Ubuntu 22.04 I got G'MIC working after:
sudo apt install gimp-plugin-registry
That didn't work on my current Ubuntu.

I don't want to make a lot of changes to my 20.04 system cause I use that for grafix
I managed to make a github page.

I hope to do more appimages because the Shradiko script can convert any deb into an appimage.

edit ....should have said this is an ...and 2.10.30
That script makes such a monster appimage and no python without side-loading packages.

For Ubuntu / Mint an appimage is not that vital. For ubuntu / mint 20 versions there is the Panda Jim PPA. For Ubuntu 18 / Mint 17 , a couple of weeks ago Ron Savoury PPA added packages for Gimp 2.10.30 I have now replaced my kubuntu 18.04 Gimp appimage with the Ron Savoury PPA installation.

However, as a recent post on pixls.us Some users can not use PPA's. This a Debian 11 user. A couple of screenshots of the appimage I made.

..and how easy is it to include python in a Mint 20 VM Still a bit of a PITA https://youtu.be/FzXdAsZlZzY 4 minutes.
An up-to-date gmic_gimp_qt plugin still needs QT5 installed and a suitable (static compiled) version.

The appimage not really needed anymore, at least for 'buntu There is a PPA that will install 2.10.30 on ubuntu focal.
When it comes to 'buntu 22.04 then an change from fuse2 to fuse3 prevents the current appimages working and the default Gimp is 2.10.30 anyway.

Thanks for testing vitforlinux

Rich2005. Python 2 reached end-of-life on 1st January 2020. Is it hard for python coders to update their Gimp plug-ins for python3? I'm not sure why there are so few python scripts for Gimp that support python 3?

I really appreciate the python scripts ofnuts and you have written. I use your 'clear alpha' a lot. I can switch the default python on my latest Ubuntu between 2 and 3 but I wonder why and for how long?

Yeah I don't know how hard it is to make the current python scripts compatible with python3. We'll find out when Gimp 3 comes out. That's why I'll still keep a Gimp 2.10.x appimage around just in case.

Once Gimp3 gets pushed down via ppa, I'll have to revert back to the default python3 anyway.

There will be migration instructions, once it's the time, I'm sure ( I hope...).
To update scripts to python3 now doesn't help : GIMP has no binding for it. It is as if GIMP doesn't know python3 even exists. That will change with GIMP 2.99/ GIMP 3.

Thanks for your update on Python3 nelo.

I just made an interesting discovery. Using the Shradiko appimage tool, I made a Gimp appimge that includes G'MIC.
The tool uses DEB packs and because Gimp is a dependency of the gimp-gmic deb, it makes the whole thing and launches Gimp with G'MIC working inside.

Its 450Mb total and I'm looking for where in the script I can thin it down.
