Ubuntu 20.04 - Trying to add resynthesizer plugin

[AlexH]

Have downloaded GIMP 2.10.32 - added resynthesizer plugin without any problems

When i try to use it, however, I get this


An error occurred running python_fu_heal_selection

error: procedure not found

Traceback (most recent call last):
  File "/app/lib/gimp/2.0/python/gimpfu.py", line 741, in response
    dialog.res = run_script(params)
  File "/app/lib/gimp/2.0/python/gimpfu.py", line 362, in run_script
    return apply(function, params)
  File "/home/alex/.gimp-2.8/plug-ins/plugin-heal-selection.py", line 148, in heal_selection

error: procedure not found
