This old post is the top hit for Googling "ubuntu gimp3 resynthesizer" so I'll add my finding here.
It seems that the Resynthesizer is only distributed via Flathub. That's a bit of a pain for Ubuntu and especially Kubuntu because installing GIMP via Flathub pulls in a huge bunch of Gnome core files to store in the flatpak directory, so the installation is huge in size. It's better to get Gimp from Ubuntu's repository.
Trying to compile Resynthesizer was problematic for me with autoconf spitting out cofusing errors, so I gave up on that. I decided that it was best to temporarily setup flatpak to grab Resynthesizer, then uninstall and cleanup flatpak afterwards. Here's how.
* Install flatpak
$ sudo apt install flatpak
* Set Flathub as the source
$ sudo flatpak remote-add flathub https://flathub.org/repo/flathub.flatpakrepo
* Get Resynthesizer, select version 3 for x86_64 when prompted
$ sudo flatpak install flathub org.gimp.GIMP.Plugin.Resynthesizer
* Copy the relevant part to a suitable directory
$ sudo mkdir -p /opt/gimp3-plugins/resynthesizer
$ sudo cp -a /var/lib/flatpak/runtime/org.gimp.GIMP.Plugin.Resynthesizer/x86_64/3/active/* /opt/gimp3-plugins/resynthesizer/
* In GIMP: Edit -> Preferences -> Folders -> Plugins
* Add path: /opt/gimp3-plugins/resynthesizer/files/plug-ins
* Restart Gimp, load an RGB-mode image
* Look for Resynthesizer in: Filters -> Map
* and Heal Selection in: Filters -> Enhance
* If it works then clean up flatpak
$ sudo flatpak uninstall --all
$ sudo apt purge flatpak
$ sudo apt autoremove
$ rm -rf ~/.cache/flatpak ~/.local/share/flatpak
$ sudo rm -rf /root/.local/share/flatpak
$ sudo rm -rf /var/lib/flatpak/*
