Calibre 6.21 AppImage start error (SOLVED)

[soniabu]

Hi everyone.
I'm trying to use the Caliber 6.21 AppImage to replace the current 5.44 that I've been using for a long time.
When I try to launch the application I get this type of error (cf. img) that I don't know how to resolve.
Could anyone who uses Calibre AppImages updated to 6.21 or 6.26 suggest me a solution?
Caliber 6.21 download from the site: https://www.appimagehub.com/p/1974121

@soniabu Dependency problem obviously. Installing libopengl0 may fix it : apt install libopengl0

BarryK found it impossible to open calibre 6.2.1 in Easy OS
He found he could get version 5.44 to work.

After Fred told me to install the missing software (see above) to start Caliber 6.26 AppImage, I realized that Caliber only opened PDFs while for epubs it gave the error img 1.
A search suggested excluding sandbox (img2 command).
So to recap;
a) Sandboxing disabled command;
b) launch of Caliber 6.26 AppImage;
c) also opening of epubs.
I point this out for anyone who finds themselves in this predicament and also to leave a historical trace(especially for my muddy memory ).
