18.04：Duplicity 停止工作

在阅读相关帖子后，我意识到 duplicity 对于备份来说是多么脆弱。无论如何，由于一些奇怪的原因，deja-dup 停止工作：

  • 首先我收到类似以下错误这（可能之前对 keyring / seahorse / gpg 做了一些小改动，但我记不清具体情况了
  • 然后我 apt-get 删除了 deja-dup 和 duplicity
  • snap 安装了两者的最新版本

现在我陷入了一个新的“已知”错误：

备份在恢复时不断要求输入加密密码

没人（包括我）能够真正从中恢复过来。

下面是我从命令行启动“snap”版 deja-dup 时的命令行输出

export DEJA_DUP_DEBUG=1  
deja-dup  --backup

这是错误信息：

我当前的 snap 版本是：

deja-dup 42.7 duplicity 0.8.19

答案1

问题在于我使用了不同的密码进行备份，而 duplicity 在备份时没有发出警告。因此，为了修复这个问题，我不得不删除使用了不同密码的文件。解释如下这里
