Thanks!

You're welcome.

To get rid of that old .config of Gimp hanging around on your system run:

sudo rm -rf /home/ale/.config/GIMP

Once that's removed your out of the woods.-

Now you can either download and install the current version of Gimp 2.10.36.
OR> use APT or Synaptic Package Manager to install Gimp.

To search with APT run:

apt-cache search gimp

To find the stable version run:

apt list gimp

*If there is an additional version in the repository the command-line will tell you to use the '-a' switch to see it.

I don't know but I think you should run GIMP v2.8 if possible, then determine what needs to be preserved.

I'm not a GIMP expert but adding another version on top of all this may not work. LOL We might confuse 'em.

I've sort of followed the thread. I'd try removing all the GIMP instances and starting over, but that's just me.

Done.
I then installed GIMP from Synaptic, but it doesn't open PNG files.
So I removed it from Synaptic and installed it from Ubuntu Software.
Now I can open PNG files but G'MIC filters don't show up.
Any ideas how to fix that?
I also tried to run GIMP from Terminal with sudo gimp but I got this result:

mkdir: cannot create directory '/run/user/0': Permission denied
Authorization required, but no authorization protocol specified
Cannot open display:

I was going to advise the latest Debian v12.3 comes with GIMP v2.10.34. But I noticed this news item on Distrowatch.

DistroWatch.com: Put the fun back into computing. Use Linux, BSD.

News and feature lists of Linux and BSD distributions.

distrowatch.com

I upgraded on two installations before taking notice of this news. I'm on another one right now but can't upgrade because of this.

EDIT: I'm sorry if I provoked anybody with this comment. I checked again and the version/release/subrelease of GIMP changed into Debian v12.4 is GIMP v2.10.34.

Just installing the GMIC the Ubuntu user said in this link is just the binary so you'll want to follow this:

gmic installed but not showing in GIMP, Ubuntu 22.04

I installed gmic for Gimp from apt on 22.04 sudo apt install gmic It's nowhere to be found in Gimp Filters or anywhere else that I can see.

Hello

I'm using GIMP 2.10.34 on Ubuntu 22.04. I also installed GMIC 3.3.1.

My problem is that GIMP doesn't open PNG files (I got an "Unknown file type" error message) and GMIC is not visible. Unless I launch GIMP from terminal, using the command sudo gimp. Then I can open PNG files and I have GMIC.

Another peculiar thing is that, if I launch GIMP from terminal, the version launched is 2.10.30.

So I'm a little bit confused and I would need some help, please.

Thank you in advance!

Checking my version it says 2.10.36 is the latest version. I am on Linux Mint 20.2. I have it installed and start from the menu.
Always,
Wildman

Thanks, I used the command "apt install gimp-gmic", the result is I still cannot see GMIC filters... BUT now I can launch gimp from terminal ("sudo gimp") and when I do so the GMIC filters show up.
I'd say it's an acceptable compromise, isn't it?
Thank you all for helping me out, a special thanks goes to @Alexzee for the patience and support!

 

[wendy-lebaron]

Why do you need superuser privilege to open the program?

If you're going to do that then do this:

sudo gimp &

then you could at least close the terminal that you had to do that in by typing exit and pressing ENTER. Otherwise, we have to find another way to do this so you could launch GIMP as your regular user account.

 

[lymphor]

If you're going to do that then do this:

sudo gimp &

Thank you, I used your command but gimp doesn't launch on my PC this way, all I got is the following result in terminal:

[1] 12054

@lymphor do you have

gimp-plugin-registry

installed?

I used the following to establish this

apt-cache rdepends gimp-gmic
gimp-gmic
Reverse Depends:
  gimp-plugin-registry
  gmic

Hello everybody,
Sorry for my latest absence, but it's been a busy period in my life and I needed a break.

@lymphor do you have

gimp-plugin-registry

installed?

Looks like I have it, yes, thank you for your suggestion.

 

[lymphor]

I recently deleted my Ubuntu and reinstalled from scratch, therefore the issue is no more. Will mark this thread as Solved, thanks everybody for your help!
