"Console is in commands mode, prefix expressions with ?" 意思是在控制台处于命令模式时,需要在命令前面加上 "?" 前缀。这样可以让控制台识别这是一両命令而不是普通的文本。

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
It seems that you are encountering an issue with connecting to the Docker daemon. This error message usually indicates that the Docker daemon is not running or is not accessible.
To resolve this issue, you can try the following steps:
1. Verify if the Docker daemon is running by using the following command:
```
sudo service docker status
```
If it is not running, you can start it using:
```
sudo service docker start
```
2. Ensure that you have proper permissions to access the Docker daemon. You may need to run Docker commands with `sudo` or add your user to the `docker` group. To add your user to the `docker` group, use the following command:
```
sudo usermod -aG docker your_username
```
Remember to replace `your_username` with your actual username.
3. If you have recently installed Docker, you might need to log out and log back in for the changes to take effect.
4. In some cases, a system reboot may also help in resolving the issue.
Please try these steps and let me know if the problem persists or if you have any further questions.
