[ros-users] [Discourse.ros.org] [Embedded] Information for those using Raspberry Pi, Ubuntu Xenial, and ROS Kinetic

[suforeman]

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`
