I am trying to install ROS Melodic using the instructions on wiki.ros.org and stumbled upon some problems.
System software information:
Operating System: Kubuntu 21.10
KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.86.0
Qt Version: 5.15.2
Kernel Version: 5.13.0-19-generic (64-bit)
Graphics Platform: X11
Problem
I have first followed steps from http://wiki.ros.org/melodic/Installation/Ubuntu and later followed the steps from https://varhowto.com/install-ros-melodic-ubuntu-18-04/#Step_1_—_Install_ROS_Melodic_repo , both with unsuccessful results.
When running sudo apt update I am getting:
Hit:1 http://archive.ubuntu.com/ubuntu impish InRelease
Get:2 http://archive.ubuntu.com/ubuntu impish-updates InRelease [110 kB]
Ign:3 http://packages.ros.org/ros/ubuntu impish InRelease
Get:4 http://archive.ubuntu.com/ubuntu impish-backports InRelease [101 kB]
Hit:5 http://packages.ros.org/ros/ubuntu bionic InRelease
Get:6 http://archive.ubuntu.com/ubuntu impish-security InRelease [110 kB]
Err:7 http://packages.ros.org/ros/ubuntu impish Release
404 Not Found [IP: 140.211.166.134 80]
Reading package lists... Done
E: The repository 'http://packages.ros.org/ros/ubuntu impish 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.
After trying to install with this line:
sudo apt install ros-melodic-desktop-full
I am getting:

I tried to concentrate on the error
E: Unable to correct problems, you have held broken packages.
But never found a solution to install ROS. I used Synaptic Package Manager to fix and remove any broken packages and tried to unhold every package to get rid of the problem but nothing worked.
Does anyone know how to solve this? Thank you!
CodePudding user response：
You're getting this error because Melodic is the ros distro for Ubuntu 18.04. As of present the most recent release is Noetic which targets 20.04. The version of Ubuntu you're using does not currently have a supported ROS release, as such your only real option is to downgrade if you want ROS.
