Old question: "Removed zsh, but forgot to change shell back to bash, and now Ubuntu crashes (wsl)" Note that @steeldriver's answer works for my new question as well.
I have been trying to install zsh on my Ubuntu terminal 20.04 (wsl). I changed the shell (using chsh) to zsh, but then I removed zsh. Then I forgot to change the shell back to bash. Now Ubuntu crashes immediately after it's launched. How can I avoid that crash without an uninstall + reinstall?
