How to Install GIMP 2.99.6 (GIMP 3.0 Dev) via PPA in Ubuntu 20.04

Last updated: September 8, 2021 — 1 Comment

For those don’t like the Flatpak package, here’s how to install GIMP 2.99.6 from PPA in Ubuntu 20.04 LTS.

The popular GIMP image editor is working on the next major 3.0 release. For testing purpose, GIMP 2.99.6 was released as the latest development version. It provides the official Linux package via Flatpak package. However, some users don’t like it, since Flatpak is an universal package format needs separate daemon to run in sandbox.

Install GIMP 3.0 Dev from PPA in Ubuntu 20.04:

For Ubuntu 20.04 and derivatives, e.g, Linux Mint 20 and Zorin OS 16, the unofficial PPA contains the classic .deb package for GIMP 3.0 Dev release.

NOTE: The package in the PPA is unstable. It may have bugs and used only for testing purpose. Installing GIMP from this PPA will override the 2.10 stable release, don’t install it on production machine.

1. Add the PPA.

Press Ctrl+Alt+T on keyboard to open terminal, or search for and open terminal from start menu if you’re on Linux Mint or ZorinOS.

When terminal opens, copy and paste the command below and hit Run to add the PPA:

sudo add-apt-repository ppa:mati75/gimp30

Type your password as sudo command need user authentication, and hit Enter to continue.

2. Update package cache

Since Ubuntu 20.04, it updates the system package cache automatically while adding Ubuntu PPAs, However, Linux Mint 20 does not. So you may need to manually run command in terminal to update cache:

sudo apt update

3. Install / Upgrade to GIMP 3.0 Dev

Finally, you can either open Software Updater (Update Manager) to install or upgrade the GIMP package, or run command in terminal instead:

sudo apt install gimp gegl

Revert to GIMP 2.10 Stable:

It’s possible to downgrade the image editor back to 2.10 stable release, 2.10.18 if no other relevant PPA added.

Simply open terminal and run the command below to install the ppa-purge package, and then purge the Ubuntu PPA which will remove it as well as downgrade installed packages:

sudo apt install ppa-purge && sudo ppa-purge ppa:mati75/gimp30

That’s all. Enjoy!

GIMP Image Editor 2.10.24 Available to Install in Ubuntu 20.04 & Higher

Last updated: April 1, 2021 — 2 Comments

GIMP extra color palettes

Before the next major GIMP 3.0, a new maintenance update for the 2.10 series GIMP 2.10.24 now is available to install.

Though it’s not officially announced at the moment of writing, GIMP has provided the 2.10.24 source tarball & Windows exe for downloading in its website.

And both the Flathub repository and unofficial Ubuntu PPA have updated the packages for the new release.

What’s new in GIMP 2.10.24 according to the release note:

  • Off-canvas point snapping
  • GeoTIFF metadata support (georeferencing information embedded within a TIFF file used by map makers)
  • Many improvements in the metadata viewer and editor
  • Many file format supports improved: HEIF, PSP, TIFF, JPEG, PNG, PDF, DDS, BMP, PSD
  • New “Negative Darkroom” operation to simulate enlargement prints from scans of photographic negatives.
  • The RAW image import now handles darktable 3.6 and over
  • New Kabyle translation

How to Install GIMP 2.10.24 in Ubuntu:

Method 1: Install GIMP via the universal flatpak package:

If you’re OK with the flatpak package which runs in sandbox, open terminal and run following commands one by one to install it:

1. Firstly add PPA for updated Flatpak package (required for Ubuntu 18.04 only):

sudo add-apt-repository ppa:alexlarsson/flatpak && sudo apt update

2. Install flatpak daemon if you don’t have it:

sudo apt install flatpak

3. Add flathub repository which hosts the software packages:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

4. Finally install GIMP flatpak package via command:

flatpak install flathub org.gimp.GIMP

NOTE: as flatpak runs in sandbox, it takes much more disk space for run-time libraries.

5. (Optional) If you want to remove the package, run command:

flatpak uninstall org.gimp.GIMP

Method 2: install GIMP via Ubuntu PPA:

For those prefer the classic .deb packages, the unofficial PPA has made the new release packages for Ubuntu 20.04, Ubuntu 20.10, and Ubuntu 21.04.

Due to compile issue, the package for Ubuntu 18.04 is stuck at v2.10.22 at the moment.

1.) Open terminal from system application launcher. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/gimp

Type user password (no asterisk feedback) for sudo prompts and hit Enter to continue.

2.) If an old version of GIMP .deb package was installed, upgrade it via Software Updater (Update Manager) utility.

or run apt commands in terminal to install GIMP:

sudo apt install gimp

If you’re going to upgrade the image editor from command line, I’d recommend to RUN this command instead, so to also install the updated dependency libraries.

sudo apt upgrade

3.) (Optional) To restore GIMP to the stock version in main Ubuntu repository, run command to purge the PPA:

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/gimp

[PPA Update] GIMP 2.10.22 with Python Script Support in Ubuntu 18.04

Last updated: January 19, 2021

GIMP extra color palettes

For Ubuntu 18.04 users sticking to the PPA build of GIMP image editor 2.10.22, now the Python Script support is back.

Since old GTK2 and Python 2 libraries being removed from Ubuntu universe repositories, the Python script support was excluded due to lack of dependencies when I was uploading the GIMP packages into PPA.

Ubuntu 18.04 was neglected, though. It meets all the dependencies to build the requested feature. So I added it back. Hope it’s not too late for you :). And the package was totally built via the rules from otto-kesselgulasch’s PPA.

Install GIMP 2.10.22 via PPA in Ubuntu 18.04:

NOTE I do only basic image editing with GIMP, and I can’t go further test for the function though it seems working.

1.) Open terminal from system application launcher. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/gimp

Type user password (no asterisk feedback) for sudo prompts and hit Enter to continue.

2.) If an old version of GIMP .deb package was installed, upgrade it via Software Updater (need to install gimp-python manually) utility.

or run apt commands in terminal to install GIMP:

sudo apt update

sudo apt install gimp gimp-gmic gimp-python

If an old version was installed, it’s recommended to run sudo apt upgrade which will also update the required babl, gegl libraries.

How to Restore:

To restore GIMP to the stock version in main Ubuntu repository, run command to purge the PPA:

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/gimp
