The install.sh for the Touch Screen Plugin has not installed the Chromium package:
echo “Installing Chromium”
sudo apt-get install -y chromium-browser -> this does not function any more!
there is an alternative in the script for the Chromium installation:
echo "Installing Chromium Dependencies"
sudo apt-get update
sudo apt-get -y install
echo "Installing Graphical environment"
sudo apt-get install -y xinit xorg openbox libexif12
echo "Download Chromium"
cd /home/volumio/
wget [launchpadlibrarian.net/234969703 ... _armhf.deb](http://launchpadlibrarian.net/234969703/chromium-browser_48.0.2564.82-0ubuntu0.15.04.1.1193_armhf.deb)
wget [launchpadlibrarian.net/234969705 ... _armhf.deb](http://launchpadlibrarian.net/234969705/chromium-codecs-ffmpeg-extra_48.0.2564.82-0ubuntu0.15.04.1.1193_armhf.deb)
This alternative was problematic for my firewall! After deactivating my firewall temporarily, the installation functions!
Now all is fine!
