Duplicity在上传到googlecloudstorag时给出了一个TypeError

Question

我有一个备份脚本，一直运作良好。我最近更新了我的操作系统（到ubuntu19.10），并试图安装所有的依赖项，但我得到了一个错误。你知道吗

我的剧本是这样的：

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，并且我可以成功地使用gsutil，因此身份验证似乎正在工作。你知道吗

回溯看起来像是一个编码/解码问题，但我不知道这是我如何做事的问题还是boto或duplicity中的错误

 TypeError: can only concatenate str (not "bytes") to str

我尝试按照建议的here对bucket变量进行解码。你知道吗

现在我得到一个SSLCertVerificationError，如下：
