[GNC] how to remove both GNC 4.2 and Flathub version 4.8 so can upgrade to 4.9 on Ubuntu 20.04lts

Jeff,
 
Just built GC4.9 on Linux Mint 20.2  (Ubuntu 20.04 based) with no problems. Give
it a go and come back to the forum with the terminal output if there are any
problems.  You can select any terminal output and cut and paste it into a text
file then attache the text file to the post to avoid putting it directly in the
post.
