OS: Xubuntu 18.04.1 64-bit
downloaded from SAGE: sage-8.9-Ubuntu_16.04-x86_64.tar.bz2
decompressed with tar -xjf sage-8.9...
I did a cd to the uncompressed folder, SageMath, and issued the command:
./sage
It then went thru a long sequence of patches, put up the following msg box:
┌┐
│ SageMath version 8.9, Release Date: 2019-09-29
│
│ Using Python 2.7.15. Type "help()" for help.
│
└┘
and then issued the Oops message.
As I recall I went through the very same sequence with SAGE 8.8 & it's
worked just fine...Dave
