--- Comment #2 from vialav <d...@bk.ru> --- Hi, Nikita, Thanks for your attention to this report. I run the following: $ which sage /usr/bin/sage $ dpkg -l sagemath Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==============-============-============-================================= ii sagemath:amd64 8.6-6 amd64 Open Source Mathematical Software You could find Sage 8.6 on https://packages.ubuntu.com/src:sagemath $ exec sage-ipython -i --simple-prompt # which Cantor invokes internally crashes under Cantor v19.07.70+git20190523 # master branch, merged into Applications/19.04 (are you verifying the same?) I tracked down this to have something related to: dpkg -l python-ipython Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==============-============-============-==================================================== ii python-ipython 5.8.0-1 all Enhanced interactive Python shell (Python 2 version) namely, initiating a "single prompt" by Cantor through Python 2, which next goes through some intricacies of the Python 3 compatibility in IPython So, there was my question: could it have been possibly done via a completely different route, as I'm able to use sage from: $ cat /usr/share/applications/sagemath.desktop | grep Exec Exec=sage --notebook=jupyter or even simpler: $ sage -python Python 2.7.15+ (default, Nov 27 2018, 23:36:35) [GCC 7.3.0] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> -- You are receiving this mail because: You are watching all bug changes.
