ROS ARM install on a custom variant of Ubuntu 18.04

Hey all, I am trying to install ROS on an ARM device that has a custom Ubuntu 18.04 variant (called 'trinity') installed, which does not come under the standard list of OS names.

Eg - when running "rosdep update"

raise OsNotDetected("Could not detect OS, tried %s" % attempted) OsNotDetected: Could not detect OS, tried ['windows', 'ubuntu', 'slackware', 'rhel', 'qnx', 'osx', 'opensuse', 'opensuse', 'opensuse', 'neon', 'mint', 'linaro', 'gentoo', 'funtoo', 'freebsd', 'fedora', 'elementary', 'elementary', 'debian', 'cygwin', 'centos', 'manjaro', 'arch']

and when i run "sudo apt-get update"

Err:3 http://packages.ros.org/ros/ubuntu trinity Release
  404  Not Found [IP: 140.211.166.134 80]

I temporarily faked the ROS OS variable 'export ROS_OS_OVERRIDE=ubuntu:18.04' I tried installing from source, however when i get to the step:

rosdep install --from-paths src --ignore-src --rosdistro melodic -y

I get these errors (shortened to show point)

dpkg-query: no packages found matching libtinyxml2-dev
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
rosconsole: No definition of [log4cxx] for OS version []

Has anyone got experience with dealing with custom OS and might know how to deal with this?

Thankyou

Trinity is just a desktop environment for your Ubuntu (and other X supporting Unix systems) and this shouldn't be a problem. What probably happened is that this distro left out some default Ubuntu packages, one of which is libtinyxml2-dev. Try installing it with apt-get and post more info.

Thanks, i installed those bits needing, but now stuck on an OS issue:

ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: rosconsole: No definition of [log4cxx] for OS version [] catkin: No definition of [log4cxx] for OS version []

etc...

Did you try to override it with only ubuntu and not the Ubuntu version number?

I did try, but i had to use the whole ubuntu:bionic, thanks for your help though.

So i finally worked out the full answer. Since Ubuntu18.04 is codenammed "bionic", You had to set:

export ROS_OS_OVERRIDE=ubuntu:bionic

And then:

rosdep install --from-paths src --ignore-src --rosdistro melodic --os=ubuntu:bionic -y

However, i worked out you could install directly from the ROS ARM basic method via cheating the sources.list when installing ROS via:

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu bionic main" > /etc/apt/sources.list.d/ros-latest.list'

This is essentially cheating "$(lsb_release -sc)" by replacing with "bionic" (for Ubuntu 18.04).

that's not "cheating": Trinity is essentially bionic, but the maintainers of that distro chose to override what lsb_release should return.

There is no distro defined for trinity on the ROS ..

.. pkg repositories, so you'll have to revert the override of Trinity to the output of lsb_release and specify the correct base name of the distribution that Trinity is using.
