[Sugar-devel] Debian Advocacy Update - Errors in Calculate on Debian Bullseye

[shaansubbaiah.cs18 at bmsce.ac.in]

Hello James,
While testing Sugar 0.117-3 on Debian Bullseye (11 / testing) I have found numerous errors which were not present while testing on Debian Buster (10 / stable).
Both versions of the activity are the same, 46. There have been a few changes made a week back:
   
   - fix recommend python3-matplotlib (not python-matplotlib); closes: bug#938584, thanks to Sandro Tosi * fix provide ${python3:Provides} (not ${python:Provides}) 

I will investigate further and report back.

Submitting trigonometric functions without values displays an error in the Activity but only the first character is highlighted red instead of the full function.
