error verifying Docker info: "Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?"

这个错误提示表明Docker守护进程没有运行。你需要确保Docker守护进程正在运行。你可以使用以下命令来启动Docker守护进程：

systemctl start docker.service

如果你已经启动了Docker守护进程，但仍然遇到此错误，请确保你的用户帐户已添加到docker组中。你可以使用以下命令将当前用户添加到docker组中：

sudo usermod -aG docker $USER

请注意，这将需要重新登录才能生效。

Verifying transaction: failed EnvironmentNotWritableError: The current user does not have write permissions to the target environment.

"Verifying transaction: failed EnvironmentNotWritableError: The current user does not have write permissions to the target environment."这个错误信息表示当前用户对目标环境没有写权限，导致交易验证失败。可能原因有以下几种：
1. 用户权限不足：当前用户没有足够的权限来对目标环境进行写操作。
2. 目标环境被锁定：目标环境可能被其他用户锁定，导致当前用户无法对其进行写操作。
3. 目标环境不存在：目标环境可能已被删除或不存在，导致当前用户无法对其进行写操作。

为解决这个问题，可以尝试以下几个步骤：
1. 检查用户权限：确保当前用户具有足够的权限来对目标环境进行写操作。如果没有足够的权限，联系管理员或拥有相应权限的用户来执行写操作。
2. 解锁目标环境：如果目标环境被其他用户锁定，联系该用户并请求解锁。
3. 确保目标环境存在：检查目标环境是否存在，如果不存在，创建新的目标环境。

java.lang.NoClassDefFoundError: scala/Serializable

This error typically occurs when a class in a Java program references a Scala class that is not available in the classpath at runtime.

To resolve this issue, you can try the following steps:

1. Check that the Scala library is properly installed and included in the classpath of your Java program. You can do this by verifying that the scala-library.jar file is present in your project's classpath.

2. Make sure that the version of the Scala library being used by your Java program is compatible with the version of Scala used to compile the referenced Scala class.

3. If you are using a build tool like Maven or Gradle, make sure that the dependencies for the Scala library are properly configured in your build file.

4. If you are still encountering the error, try cleaning and rebuilding your project, as it may be caused by a caching issue.

If none of these steps resolve the issue, you may need to provide more information about your environment and the specific code that is causing the error to receive further assistance.
