Since updating to ubuntu 22.04 (and installing the PPA version of Firefox), sagemath stops working: The sagemath9.5 kernel cannot be connected to jupyter. Removin and reinstalling has no effect what todo?
here is how I solved this problem and icing on the cake it solved the problem of windows SageMath shortcuts which no longer allowed to launch firefox. with leaving Ubuntu22.04 and returning to Ubuntu20.04 !
# I must precise that before that I first uninstall ubuntu with settings --> apps ->installed apps -> ubuntu
# but it could be not neccessary
# in PowerShell cmd :
wsl --unregister ubuntu
wsl --list --online
wsl --install -d Ubuntu-20.04
sudo apt update
sudo apt upgrade
search Ubuntu in apps and launch it
#in ubuntu cmd
sudo apt update
sudo apt upgrade

wget http://www.mirrorservice.org/sites/www.sagemath.org/src/sage-9.7.tar.gz
tar xvf sage-9.7.tar.gz
cd sage-9.7
./configure
make -j32 # 16 cores so -j32 twice the cores #
cd ~
#edit sage_nb.sh
nano sage_nb.sh
#put theses 3 lines below in it (replace ortollj by your linux user name):
#!/bin/bash
cd '/mnt/c/Documents and Settings/user/Mes documents/IPYNBpc'
/home/ortollj/sage-9.7/sage --notebook jupyter
# make it executable
chmod ug+x sage_nb.sh

#( for me ubuntu2004.exe but it could be ubuntu.exe , please check the location)
#C:\Users\User\AppData\Local\Microsoft\WindowsApps
Create windows shortcut
This is a final nicety that lets you start the JupyterLab server in one click:
Open Windows explorer, and type %APPDATA%\Microsoft\Windows\Start Menu\Programs
Make a copy of any of the program icons – we’ll customise it to do what we want
Right-click, and choose properties.
On the General tab:
Change the name to whatever you want.
On the Shortcut tab:
Change Target to: C:\Users\User\AppData\Local\Microsoft\WindowsApps\ubuntu2004.exe run ~/sage_nb.sh
Change Start in to: %USERPROFILE%
Change Run to: Minimised
Change the icon if you want – there are plenty of pieces of software that can create a .ico icon file one from an image file.
Now hit the start button or key and type the name you gave it. it should appear in the list, and should load the server and fire up your browser when you click on it.
where do I get these informations :
https://pureinfotech.com/uninstall-ws...
alias h=history
alias sage=~/sage-9.7/sage
But trying to suppress error :tcgetpgrp failed: Not a tty
by putting these 3 lines below(choose your prefered Web Browser) in ~/.bashrc
# export BROWSER='/mnt/c/Program Files/Google/Chrome/Application/chrome.exe'
export BROWSER='/mnt/c/Program Files/Mozilla Firefox/firefox.exe'
#export BROWSER='/mnt/c/Program Files (x86)/Microsoft/Edge/Application/msedge.exe'
The kernel connection problem had come back ! so I comment all these 3 lines and then all is ok except
this tiny error :tcgetpgrp failed: Not a tty
I ask myself if the line:sudo apt-get install autoconf automake git gpgconf libtool openssh openssh-client pkg-config
should be replaced by
sudo apt-get install autoconf automake git gpgconf libtool openssh-server openssh-client pkg-config
to avoid the error message :E: Unable to locate package openssh
from install from source
The problem may be because of a conflict with the new version of python installed by the upgrade. This may be overkill, but when it happened to me with sage-9.7, rebuilding sage solved the problem.
To build Sage 9.7 from source in Ubuntu 22.04, you may follow these steps: https://sagemanifolds.obspm.fr/instal...
W11 WSL UBUNTU 22.04 SageMath 9.7
Since yesterday I encounter a strange phenomenon with Jupyter notebook.
Every time I want to open one of my saved SageMath .ipynb file I encounter a problem connecting to the kernel,
However I can open a new virgin .ipynb file and write SageMath code in it and everything works.
I have however found a very curious workaround to use my saved SageMath ipynb files.
I launch sage in Ubuntu with no Jupyter notebook, only sage,
I leave it with exit, then I launch sage --notebook jupyter, and only after that,
I can open one of my old ipynb files which then connects to the kernel !!
No for me @richardquint the problem is not resolved after reinstalling SageMath. Very weird.

This might be a duplicate of https://ask.sagemath.org/question/641.... See also https://trac.sagemath.org/ticket/34593. Can you run Sage from the command line, or does that fail, too?
