Hello >From trial and error, my workaround is to downgrade python3-cypari2. I have no idea whether it is appropriate or if it is going to trigger something else, but at least I don't have a startup crash anymore. Here are the steps: - add "deb https://snapshot.debian.org/archive/debian/20200628T024451Z unstable main" to /etc/apt/sources.list - sudo apt -o Acquire::Check-Valid-Until=false update - sudo apt install python3-cypari2=2.1.1-2+b2
It seems it is a recurring situation, 906796 happened two years ago. -- Sylvain
