[英]Trouble installing ROS Melodic Ubuntu 21.10
我正在尝试使用 wiki.ros.org 上的说明安装 ROS Melodic，但偶然发现了一些问题。
系统软件信息：
操作系统：Kubuntu 21.10
KDE 等离子版本：5.22.5
KDE 框架版本：5.86.0
Qt 版本：5.15.2
Kernel 版本：5.13.0-19-通用（64 位）
图形平台：X11
我首先遵循http://wiki.ros.org/melodic/Installation/Ubuntu的步骤，后来遵循https://varhowto.com/install-ros-melodic-ubuntu-18-04/#Step_1_%的步骤E2%80%94_Install_ROS_Melodic_repo ，都没有成功的结果。
运行sudo apt update我得到：
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

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.
尝试使用此行安装后：
sudo apt install ros-melodic-desktop-full

我试图专注于错误
E: Unable to correct problems, you have held broken packages.
但从未找到安装 ROS 的解决方案。 我使用 Synaptic Package 管理器来修复和删除任何损坏的软件包，并试图取消每个 package 以解决问题，但没有任何效果。
有谁知道如何解决这个问题？ 谢谢！
您收到此错误是因为 Melodic 是 Ubuntu 18.04 的 ros 发行版。 截至目前，最新版本是针对 20.04 的Noetic 。 您使用的 Ubuntu 版本目前没有受支持的 ROS 版本，因此如果您想要 ROS，您唯一真正的选择是降级。
