Install GIMP 2.10.18 in Ubuntu:

Neither the PPA repository nor GIMP Snap package are updated to v2.10.18 at the moment of writing.

However, GIMP Flatpak package has been updated for Ubuntu 18.04 and higher. Simply open terminal from application menu and run following commands one by one:

1. Install flatpak framework:
```
sudo apt install flatpak
```

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
```
3. Install GIMP flatpak package:
```
flatpak install flathub org.gimp.GIMP
```
4. If an old GIMP Flatpak version was installed, update it via command:
```
flatpak update flathub org.gimp.GIMP
```

GIMP Flatpak co-exists with Snap and native .deb packages. Run command to start it if you have more than one GIMP icon, and don’t know which one to run.
