Gmic 4.0.5 not showing under filter. Using GIMP 3.2.6

Wilcocliw · **Joined:** Oct 03, 2026 **Posts:** 3

Though I see this has been solved, however I have just started to have this problem, I am a Linux Mint user.

This problem only started today however uninstalling GIMP 3.2.6 (Flatpak) didnt help etc.

please let me know if I need to make a new topic for this,

Kind regards.

Welcome to Gimp Chat!

Glad to have you here.

I'm afraid I can't be much help with the Linux Mint/Flatpak side of this,
as I'm more familiar with the Windows setup.

Since G'MIC was working for you before and has now disappeared from the Filters menu,
hopefully one of our Linux users will be able to point you in the right direction.

I'm sure someone here has run into this before.

The only stable versions for Linux are...

Ubuntu 26.04 Resolute: stable (or latest dev)
Debian 13 Trixie: stable (or latest dev)

Welcome to Gimp Chat btw!

If you want to keep GIMP as a flatpak you have to install GMIC as a flatpak as well.
Open a terminal and paste this in

Code: Select all

flatpak install org.gimp.GIMP.Plugin.GMic

It'll then tell you that there are three versions, which one you want. Choose branch 3.

Alternatively you can use GIMP from PPA form Panda Jim:
https://launchpad.net/~ubuntuhandbook1/ ... ntu/gimp-3
Then you can use a "normal" GMIC version.

That is only true, if your base linux is 'buntu 26.4 If using a 'buntu 24.04 (or a Mint 22.3) and PPA, you need one compiled for that base.

Not difficult to compile but I do keep a binary here. https://www.gimp-forum.net/Thread-Gimp3 ... 3#pid47023 bottom of that post a gimp_gmic_qt 4.0.4 ( I do have a 4.0.5 but very lazy and have not updated the archive, will do it soon)

Thanks for the kind words and welcomes,

so originally I had it installed via flatpak and that worked fine untill yesterday (3rd of octobre 2026).
I use Linux Mint 22.3 - Cinnamon 64-bit.

I have tried to unpack in the plugins folder under .config however that didnt do anything at all.
I also have tried the PPA method however Gmic still wasnt showing up

Weird thing is, is that resynth and the Healing plugin work fine and they show up under the filters tab.
Only weird thing is that they (before unpacking into ~/.config/GIMP/3.2/plug-ins/) also didnt show up in that folder.

Okay, update:

I installed the system package version next to the flatpak and now Gmic (as well as the other plugins) do show up when I use the System package version of GIMP.
