Revision history [back]

Thanks for the detailed replies. I got it all cleaned up and running smoothly now.

I did have some trouble manually deleting the ROS installations and trying to start again with apt because apt thought some things were still installed and skipped them. I'm sure there's a smarter way I could have gone about all this, but I ended up recursively running "sudo dpkg --remove --force-remove-reinstreq package_name" on all the ros-foxy packages listed in /var/lib/dpkg/info. Then I could start again with "sudo apt install ros-foxy-desktop" and all is well so far.

The understanding helps thought so thanks again. I read through the installation documentation in more detail and it talks about this in detail and I just missed it...
