Wasn’t really sure where I should put this, so feel free to move it to a more suitable forum!
I think a few problems arise when people are not using the up to date Volumio UI from the git hub. This is just a quick draft written by a relative Linux newbie so I’m sure the more experienced members will chime in and improve it. But, here we go. Simply copy this text to a file on your Volumio OS, make it executable with ‘sudo chmod 777 FILENAME’ and run with ‘sudo ./FILENAME’ to update your Web UI.
echo "$(tput setaf 1)[+] Updating system...$(tput sgr 0)"
apt-get -y update; apt-get -y upgrade
echo "$(tput setaf 1)[+] Installing Git$(tput sgr 0)"
#install git
apt-get -y install git-core
echo "$(tput setaf 1)[+] Cloning Volumio from github$(tput sgr 0)"
#git clone the Volumio-WEBUI into our nginx webserver directory
rm -rf /var/www
git clone https://github.com/volumio/Volumio-WebUI.git /var/www
echo "$(tput setaf 1)[+] Setting permissions and copying config files$(tput sgr 0)"
chmod 775 /var/www/_OS_SETTINGS/etc/rc.local
chmod 755 /var/www/_OS_SETTINGS/etc/php5/mods-available/apc.ini
chmod -R 777 /var/www/command/
chmod -R 777 /var/www/db/
chmod -R 777 /var/www/inc/
#copy relevant configuration files, preserving permissions
cp -arp /var/www/_OS_SETTINGS/etc /
#optionally remove git just to clean things up.
#apt-get -y remove git-core
echo "$(tput setaf 1)[+] All done! please reboot with sudo reboot$(tput sgr 0)"
then run ‘sudo reboot’ just to be sure and your new Web-UI will be up and running.
