Hi,
I went through other posts with the same title, and tried several different
ways to install sage, all without success :
1) with apt : apt-get install sage-jupyter
2) downloading the latest Ubuntu 16 binary : since there are no Ubuntu 18
binary I chose the most recent one, then ran sage.
In both cases I had the same crash at runtime, with the Sage_crash_report
attached.
Does anyone have a clue ?
Best regards
Augustin Lefèvre
