I have a Pi 2 that has been kept current with the latest Raspian. I am trying to install the Pixel update that was posted on the Raspberry Pi blog this morning. Here are the commands:
sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install -y rpi-chromium-mods sudo apt-get install -y python-sense-emu python3-sense-emu sudo apt-get install -y python-sense-emu-doc realvnc-vnc-viewer
The first two commands appear to execute correctly. Line 3, installing the chromium piece, fails, as it cannot find rpi-chromium-mods.
