This is "hopefully" a point in time statement: The following refers to images from this source: https://wiki.ubuntu.com/ARM/RaspberryPi For those who are using or plan to use the Ubuntu 16.04 Xenial server builds for Raspberry Pi 3 (and 2), it is important to immediately disable `unattended updates` and avoid `apt-get ungrade`. There are known issues with various patches which have been introduced after 1034. These patches make the Raspberry Pi unstable - primarily during the boot process. The result is the Raspberry Pi will sometimes freeze during boot. Several re-attempts (power cycling) and the system may eventually boot. Occasionally even this is insufficient. By installing the original images and not permitting upgrades of core kernel files, the RPi + Ubuntu Xenial + ROS Kinetic is stable. Background: Launchpad thread: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1652270 Temporary solution to prevent a system from upgrading critical kernel files: `sudo apt-mark hold linux-raspi2 linux-image-raspi2 linux-headers-raspi2` --- [Visit Topic](https://discourse.ros.org/t/information-for-those-using-raspberry-pi-ubuntu-xenial-and-ros-kinetic/1205/1) or reply to this email to respond.
