我有一个运行良好的备份脚本。我最近更新了我的操作系统(到 Ubuntu 19.10(并尝试安装所有依赖项，但我收到错误。
我的脚本是这样的：
export PASSPHRASE="passphrase"
PATH=$PATH:/home/jeremy/.boto
export HOME='/home/jeremy/'
DATE=`date +%Y-%m-%d:%H:%M:%S`
echo "Running backup at $DATE" >> /home/jeremy/.backup/log
duplicity --full-if-older-than 1M
--archive-dir /home/jeremy/.cache/duplicity/
/home/jeremy
gs://x1_carbon_backup >> /home/jeremy/.backup/log
我用gsutil创建了.boto文件，我可以成功地使用gsutil，因此身份验证似乎正在工作。
回溯看起来像一个编码/解码问题，但我无法判断这是我做事方式的问题还是boto或duplicity中的错误

使用--s3-use-new-style作为标志。从 Duplicity 手册页：
--s3-use-new-style
When operating on Amazon S3 buckets, use new-style subdomain bucket addressing. This is now the preferred method to access Amazon S3, but is not backwards
compatible if your bucket name contains upper-case characters or other characters that are not valid in a hostname.
This option has no effect when using the newer boto3 backend, which will always use new style subdomain bucket naming.
