I just did a fresh HifiberryOS install on my new Hifiberry DAC+Pro on a RaspberryPi 4 and I am trying to install brutefir but when I ssh into the pi as root I notice sudo and apt commands are not found. Many of the guides on here use sudo apt commands, anyone know whats going on?
# sudo
-bash: sudo: command not found
#
# apt
-bash: apt: command not found
#
# which apt
#
You can't do this. HiFiBerryOS isn't designed to install 3rd party software on it.If you want to install your own software, you should start with a standrad Raspbian.
so how to install Beocreate2 on Raspbian?
You can't do this easily. Beocreate and HiFiBerryOS are tightly integrated. While it might be possible to port the Beocreate software to use it on other systems, it will probably be a lot of work. I don't know somebody who tried this.
Missing "sudo" command is a real bad thing. Why? For example:
My hifiberry will be a music streamer running 24x7. I woud like to reduce the power consumption by deactivating all USB Ports and the HDMI connector. It reduces the idle power to 0,7 W from 2.1 W. You can use it by a script with these 2 commands:
echo '1-1' |sudo tee /sys/bus/usb/drivers/usb/unbindsudo /opt/vc/bin/tvservice -o
I created a script with these commands an put it in /home.
Then, I put the line in the /etc/rc.local file:
sudo /home/savepowerscript.sh
But it does not work because there is no "sudo" command. On "Volumio" it worked fine, but I would like to use hifiberry with the DSP module. Why don't you include sudo in the hifiberry image? It is not understanable to me.
Is it possible to install it somehow afterwards?
I tried simply to set this command manually with the root user:
echo '1-1' |tee /sys/bus/usb/drivers/usb/unbind
It worked: hifiberry went to 0,6 Watt - but how to set this commend during reboot automatically? Any ideas? I tried serveral way - but without success.
