Installing-gimp-plugin-registry-into-Gimp-2.10

TL;DR

$ sudo mkdir -p /usr/lib/gimp/2.0/plug-ins
$ sudo apt install gimp-plugin-registry

Then if Flatpak

$ cp -r /usr/lib/gimp/2.0/plug-ins ~/.var/app/org.gimp.GIMP/config/GIMP/2.10

or if Snap

$ cp -r /usr/lib/gimp/2.0/plug-ins ~/snap/gimp/47/.config/GIMP/2.10

Slightly Longer explanation

To easily download around 100 plugins on Linux install the 'gimp-plugin-registry'

1. First ensure plug-in folder exists. If you already have 2.8 install it will exist but just to make sure $ mkdir -p /usr/lib/gimp/2.0/plug-ins

2. Install the 'gimp-plugin-registry'for Debian/Ubuntu this is $ sudo apt install gimp-plugin-registry

This installs a bunch (100 ish) plugins into usr/lib/gimp/2.0/plug-ins

3. copy the plugin scripts to the 2.10 folder

If you've installed via Flatpak GIMP install $ cp -r /usr/lib/gimp/2.0/plug-ins ~/.var/app/org.gimp.GIMP/config/GIMP/2.10

If you've installed via Snap GIMP Install $ cp -r /usr/lib/gimp/2.0/plug-ins ~/snap/gimp/47/.config/GIMP/2.10
