@jmvdv seems those pesky linux monsters are out to get me…Im using the same commands and now I get this

debconf: delaying package configuration, since apt-utils is not installed

Any ideas?
I used the same exact commands as last time that worked on the same Rpi Volumio image but I can’t get roon on it like I did last time with the following
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install bzip2
sudo apt-get install mc
Then for installing Roon Bridge armv7hf
curl -O http://download.roonlabs.com/builds/roonbridge-installer-linuxarmv7hf.sh
chmod +x roonbridge-installer-linuxarmv7hf.sh
sudo ./roonbridge-installer-linuxarmv7hf.sh

 sudo apt-get -f install

I think I might just try and refresh back the original img and start again…I did try and install a touch screen extension and then uninstalled it so  maybe that screwed something up.
              
same thing again…sadly not going well even on a clean flash
I think its maybe just the bzip2 application I need to unpack the roon bridge download.
I can’t understand why it all worked the first time i tried it on your instructions and this time (same hardware exactly) its not.
Anyway thanks Julius … I guess its back to the drawing board.
              
Sadly much the same still…I posted in the link on Volumio forum now too - I think its just the bzip2 that needs to be installed but that alone causes a similar error message.
volumio@volumio:~$ sudo apt-get update && sudo apt-get install systemd

I don’t use Volumio anymore. I’m now using Mopidy. It’s more work to set up, but it’s also far more flexible (here is a blog post how I set it up).
If you don’t want the hassle of installing Mopidy you could also try Rune Audio. It shares some similarities with Volumio (both originate from the same project I believe).
              
for whatever reason I have no idea the exact same commands today work perfectly and I can install Roon Bridge under Volumio again - must have been something messed up in the repositories
This time all that was needed is as follows
sudo apt-get update
sudo apt-get install bzip2
curl -O http://download.roonlabs.com/builds/roonbridge-installer-linuxarmv7hf.sh
chmod +x roonbridge-installer-linuxarmv7hf.sh
sudo ./roonbridge-installer-linuxarmv7hf.sh
I hate computers sometimes 
              
I’ve added a 7" LCD display and case from element 14 to the volumio/roon bridge setup with some case mods…pretty happy so far managing to squeeze the IQAudIO DigiAMP+ in there too with some degree of success.  I’ll do a build log sometime soon too

Great wizard I am new to Volumio and diet pi

I see you have mastered the dark art of loading Roon Bridge to Volumio

Is there any chance I could get some guidance starting from
switch on monitor.
Start raspberry pi

3…  oh god someone speak English to me this is killing me
