Make it your default shell: chsh -s $(which zsh) or use sudo lchsh $USER if you are on Fedora.
…
If you use lchsh you need to type /bin/zsh to make it your default shell.
Hey Stephanie! I don’t know if you’ve been able to resolve this yet, but i ran into the same issue yesterday and found your post. What ended up working for me, as silly as it sounds, was just:
Right clicking on the terminal
Selecting edit current profile
Then changing command in general settings from /bin/bash to /bin/zsh
While the information is great for reference, the original post was from 3 years back. Please consider using this for reference, but I am closing it to avoid continuing this necro thread.
