I’ve bought a PiGlow and would like to use it to display information from Volumio. However I’m having real trouble installing RPi.GPIO.
I imagine this is because Volumio has been stripped down and only contains the essentials from Raspbian. As a result I get all sorts of errors from trying tutorials. Can anyone provide some steps which are guaranteed to work? I’d like to get on with trying to achieve the end goal but am stuck at the first hurdle 
I’m having the same problem. I can’t install python-dev because of the following errors
The following packages have unmet dependencies:
python-dev : Depends: python (= 2.7.3-4+deb7u1) but 2.7.5-5 is to be installed
Depends: python2.7-dev (>= 2.7.3-1~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Hello,
maybe this post will show into the right direction:
rpi-volumio-gpio-for-python-t1491.html
change in /etc/apt/sources.list wheezy to jessie
sudo apt-get update
sudo apt-get install python-dev
Unfortunately I could not install gpio, so I got the gpio*.deb from the web and did:
sudo dpkg - i gpio???.deb
change in /etc/apt/sources.list jessie to wheezy
sudo apt-get update
