After install TTY using zsh but how to change it back to bash?

I prefer to use Bash in the Terminal Konsole, which i already successfully changed.

But TTY is using after install by default also zsh. Any idea how to change TTY back to bash?

Edit:
Im looking for a way to permanently change it to bash, not a command which i have to use again and again.

chsh -s /bin/bash

and

sudo chsh -s /bin/bash

for root

Is this in a fresh installation from a Plasma ISO? If so, this should not be the case — or at least, not for the Plasma Edition — and then it should be reported on the thread regarding the development of the new 26.1.0 ISOs.

It is the case for the Plasma ISO but installed with one of the PREVIEWS and it wasn’t the latest RC… my ISO was 2 weeks old.

Anyways, i found the perfect solution already:

chsh -s /usr/bin/bash

It requires a reboot to work, credits to @linux-aarhus

No, you don’t need to reboot. Simply logging out and back in should already do the trick.
