[sage-support] sage-10.0 not working in Jupyter Lab
I have just installed version 10.0 from source (in Debian Sid). Everything seems to work fine, but the usual method to add Sage to Jupyter Lab does not work. I created a symlink as usual: $ ll /home/finotti/.local/share/jupyter/kernels Permissions Size UserGroup Date Modified Name drwxr-xr-x - finotti finotti 28 Mar 13:20 magma/ drwxr-xr-x - finotti finotti 28 Mar 11:38 python3/ lrwxrwxrwx62 finotti finotti 28 Mar 13:19 sage -> /home/finotti/src/sage-9.8/venv/share/jupyter/kernels/sagemath/ lrwxrwxrwx63 finotti finotti 29 May 10:31 sage-10.0 -> /home/finotti/src/sage-10.0/venv/share/jupyter/kernels/sagemath/ Sage 9.8 works as expected, but 10.0's kernel does not work.
