Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
pisound : Depends: pisound-btn (>= 1.06-1) but it is not going to be installed
Depends: pisound-ctl (>= 1.03-1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Updating /usr/local/pisound…
sh: 1: cd: can’t cd to /usr/local/pisound

Now you may run sudo pisound-config to customize your installation!
volumio@paul-musikus:~$ sudo pisound-config
sudo: pisound-config: command not found
volumio@paul-musikus:~$ sudo pisound-config
sudo: pisound-config: command not found
volumio@paul-musikus:~$

Can someone help me with this?

Hi, what output do you get if you run:

sudo apt install pisound-btn

I’m having the same problem.
I get “some packages could not be installed.
The following packages have unmet dependencies:
pisound-btn-armhf”

Then there are some python 3 messages of things “is not going to be installed”.
Ending with:
“Unable to correct problems, you have had broken packages”
