I want to work on REEM-C simulations in Gazebo but my development box is running Bionic Beaver. So I retrieved a computer from storage and went to ubuntu.com to get 16.04 os. Got the box to work great after 3 or 4 failed attempts.

Getting ready to download ROS again but I noticed that I may still have a problem going forward. The ubuntu.com OS that finally worked on my test box is/was ubuntu-16.04-desktop-i386.iso and the OS called out in ROS.org says in REEM-C's tutorial “Ubuntu installation” to first download ubuntu-16.04.4-desktop-amd64.iso

Question: Can I proceed with REEM-C simulation in Gazebo? Or do I have to wget the exact iso that is called for? Thank you for your advice in advance.

What is the output of cat /proc/cpuinfo?

You should target ubuntu 16.04 64 bit version. That is the ISO that is linked on the PAL Robotics tutorials, 32 bit is probably not as well supported.

I can't say anything about whether things run, but they will at least compile: I've just tried it in a i386/ubuntu:xenial container. Following the instructions here results in a Kinetic workspace with all REEM packages built successfully.


Edit: trying to roslaunch reemc_gazebo reemc_empty_world.launch results in at least one Eigen alignment assertion, so that would seem to point to issues using this code on a 32 bit Ubuntu installation.

@ju78iklo9: I would second @Victor Lopez's suggestion and try to see whether you can install an amd64 version of Ubuntu on your PC.
