Hi,
After trouble getting PWM pins work on Ubuntu 14, I took the advices in this forum to install 13. So I moved BBB back to 13. Got 3.8.13-bone20 kernel. Wanted to upgrade further as suggested by many other posts by doing:
sudo apt-get update
sudo apt-get install linux-3.8.13-bone68
sudo reboot
But “sudo apt-get update” itself would fail as below. Then I realized this was the original reason I moved to Ubuntu 14. Why would the support for Ubuntu 13 be removed so fast when Ubuntu 14 is not yet mature? Working of sudo apt-get update is important for me also to get "sudo apt-get install build-essential python-dev python-setuptools python-pip python-smbus -y " work as required by “http://learn.adafruit.com/downloads/pdf/setting-up-io-python-library-on-beaglebone-black.pdf”. Any help is greatly appreciated.
