I am trying to install ROS on ubuntu 21.04 but this error is shown to me when I run sudo apt update
on the terminal. Also, I tried to use the Mirror repo but the same error is shown to me.
E: The repository 'http://packages.ros.org/ros/ubuntu hirsute Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
CodePudding user response:
There is no ROS release for 21.04. The latest distro is Noetic which targets 20.04. You'll either need to downgrade or try to install it in some 20.04 container(i.e. docker)
