I tried to change root's shell with chsh command, but now I get an error when I try to connect as root with sudo -i.
$ sudo -i
sudo: /usr/bin/bash: command not found
What do I have to modify to get the bash shell?
command-line bash root chsh

Assuming that you have not modified the path or created symlink, the default path to the bash binary is /bin/bash, not /usr/bin/bash.
The error is occurring because you have set the root's shell as /usr/bin/bash in /etc/passwd like:
root:x:0:0:root:/root:/usr/bin/bash
You need to change that to /bin/bash:
sudo usermod -s /bin/bash root
or do:
sudo vipw
and make the modifications manually.
You can obviously choose any other shell of your choice, just make sure that the path is correct. A common place to look for shell paths is /etc/shells file which contains the full paths to all the valid login shells on the system.

@SandraRoss If you are confident you can obviously do that. But i would suggestvipwas it will do the sanity checkings (e.g. syntax) over the changes to make sure everything is in place.

If you don't want to usse vipw, you can check the integrity of /etc/passwd with pwck
