I use a shutdown-script to backup the files on an instance before it is shutdown. In this shutdown-script, the gsutil tool is used to send files to a bucket at google cloud storage.

/snap/bin/gsutil -m rsync -d -r /home/ganjin/notebook gs://ganjin-computing/XXXXXXXXXXX/TEST-202104/notebook

It worked well for long days. But recently, there occurs some error as below.

If I run the code manually, it works well. It seems that there is something wrong with jobs management of systemd.

Could anyone give me some hint?

 INFO shutdown-script: /snap/bin/gsutil -m rsync -d -r /home/ganjin/notebook gs://ganjin-computing/XXXXXXXXXXX/TEST-202104/notebook

  1. 使用 -f 选项更新 gsutil。

    更新 gsutil -f

    如果上述命令不起作用，请尝试以下命令：

    sudo apt-get update && sudo apt-get --only-upgrade install google-cloud-sdk

  2. 更新来宾环境并尝试关闭实例。使用下面的链接作为更新来宾环境的参考。

  3. 如果仍然面临问题，请强制关闭：

    sudo poweroff -f
