[Stephen Liu]

Hi rich

Start Ubuntu20.04 on SSD hard-drive

Download gimp-mathmap-20-04focal.AppImage

$ chmod +x gimp-mathmap-20-04focal.AppImage
$ ls -al gimp-mathmap-20-04focal.AppImage

Code:

-rwxrwxr-x 1 satimis satimis 11584704 Jun  3 12:48 gimp-mathmap-20-04focal.AppImage

Install fuse
$ fusermount --version

Code:

fusermount version: 2.9.9

I'm not allowed to install gimp-python

$ apt policy python

Code:

python:
 Installed: (none)
 Candidate: (none)
 Version table:

python is not on repo.

Clicking gimp-mathmap-20-04focal.AppImage starts GIMP

Python-Fu filter is not there.  What can I do?  Thanks
