Description Nikita Sirgienko 2020-11-11 10:49:06 UTC 
Originally reported in this bugreport: https://bugs.kde.org/show_bug.cgi?id=428611
SUMMARY
Cantor don't work with Sage 9.2: computation don't run and each run of entry causes sage crash and Cantor prints, what the sage process has finished unexpectedly.

STEPS TO REPRODUCE
1. Install (or build) Cantor with Sage backend
2. Install Sage 9.2 and configure Cantor to use it
3. Start sage session and try to execute "2+2"

OBSERVED RESULT
Cantor prints, that sage process finished unexpectedly and the entry have been interrupted.

EXPECTED RESULT
Got result of the entry with "4" and entry marked as finished successfully

ADDITIONAL INFORMATION
Comment 1 Nikita Sirgienko 2020-11-11 10:50:35 UTC 
The problem have been found: Sage since version 9.2 stop automatically sourcing sage-env-config, which needed for sage-env, which used by Cantor for running sage (in cantor-execsage script).
