Apt can't find melodic (on Ubuntu Focal/20.04)
So I finished an installation of noetic before I realized that the most updated version of the LIDAR driver I was looking to use was only compatible with kinetic or melodic.
So I uninstalled noetic with the following commands:
sudo apt remove ros-noetic-*
sudo apt autoremove
then I removed the noetic entry from my bash, and deleted the
ros-latest.list file
from the
/etc/apt/sources.list.d/
directory.
But now when I try to follow the steps to install melodic, I get a
E: ros-melodic-desktop-full not found error
The only thing different when I follow the steps for noetic would be the fact that I get a 'number of keys unchanged' message, but I'm not sure if that matters since noetic and melodic seem to use the same command for that.
I'm at a loss right now, and I'd appreciate it if anyone can point me in the right direction. Thanks!
