Ubuntu 18.04安装Docker步骤以及错误解决方法
sudo apt-get update
sudo apt-get install \
ca-certificates \
curl \
gnupg \
lsb-release
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
执行上述命令，却报以下错误：
jason@ubuntu:~$ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
gsettings-desktop-schemas : Breaks: mutter (< 3.31.4) but 3.28.4+git20200505-0ubuntu18.04.2 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
解决方案：
jason@ubuntu:~$ sudo apt install gsettings-desktop-schemas
jason@ubuntu:~$ sudo apt install build-essential
- 然后重新安装：
jason@ubuntu:~$ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
测试是否安装成功：
jason@ubuntu:~$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
