"E:“的部分看起来像是错误，但我不知道该如何修复这些错误。

Answer 1

也许您在您的apt配置中缺少了一些源。

来自ros官方文档- https://docs.ros.org/en/foxy/Installation/Ubuntu-Install-Debians.html

安装源

您需要将ROS 2 apt存储库添加到系统中。首先，通过检查此命令的输出，确保启用了Universe存储库。

apt-cache policy | grep universe

这应该输出如下一行：

500 http://us.archive.ubuntu.com/ubuntu jammy/universe amd64 Packages
    release v=20.04,o=Ubuntu,a=jammy,n=jammy,l=Ubuntu,c=universe,b=amd64

如果您没有看到像上面这样的输出行，那么使用以下说明启用Universe存储库：

sudo apt install software-properties-common
sudo add-apt-repository universe

现在将ROS 2 apt存储库添加到您的系统中。

sudo apt update && sudo apt install curl gnupg2 lsb-release
sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key  -o /usr/share/keyrings/ros-archive-keyring.gpg

然后将存储库添加到源列表中。

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(source /etc/os-release && echo $UBUNTU_CODENAME) main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null

在设置了存储库之后，更新apt存储库缓存。

sudo apt update

您使用的是哪种版本的ubuntu？我对22.04也有同样的问题，但没有得到支持。我安装了20.04，然后就成功了。
