I'm new to Ubuntu and I was trying to download gazebo 11 and I did but now every time I try to update or install it's keep coming up with this error saying
E: Malformed entry 1 in list file /etc/apt/sources.list.d/gazebo-stable.list (Suite) E: The list of sources could not be read.
These are the file contents
deb http://packages.osrfoundation.org/gazebo/ubuntu-stable bionic main
Can you help me please? Thank you
