Trouble setting up noetic environment on Ubunutu 20.04

edit

I completed the install tutorial on the ROS website, http://wiki.ros.org/noetic/Installati.... Everything worked up to step 1.5, where I get this error message.

nick@nick-Laptop:~$ echo "source /opt/ros/noetic/setup.bash" >> ~/.bashrc
    nick@nick-Laptop:~$ source ~/.bashrc
    bash: source/opt/ros/noetic/setup.bash: No such file or directory
    bash: source/opt/ros/noetic/setup.bash: No such file or directory
    bash: source/opt/ros/noetic/setup.sh: No such file or directory
    bash: source/opt/ros/noetic/setup.bash: No such file or directory
    bash: source/opt/ros/noetic/setup.bash: No such file or directory
    nick@nick-Laptop:~$

I've done this setup step several times and each time I do it an additional

bash: source/opt/ros/noetic/setup.bash: No such file or directory

line appears. The first time it was just one, then I did it again and got two, ect. The one in the middle with setup.sh was because I saw a similar problem on a different forum and the .sh fixed it for them, but not for me. ROS is definitely installed, I can run roscore, open turtlesim, and move the turtle around, but the error confuses me. I'm pretty new to linux, and all I really understand is that the echo command is being called a bunch of times when I don't really want it to.
