最近几天，我一直尝试在 Deja Dup 上进行新的备份，但出现错误：
Backup Failed
Failed with an unknown error.
Traceback (innermost last):

尽管显示了上述错误，但 Deja Dup 现在显示“上次备份是今天”，但如果我进入恢复状态，唯一可以恢复的备份是几个月前或更早的备份——从我上次备份开始。
Deja Dup 版本 37.0 在 Ubuntu 18.04.3 LTS 上运行，我正在尝试备份到外部驱动器（而不是远程谷歌驱动器） - 它确实有足够的可用卷。
我的问题似乎与这里相同：Deja dup 备份失败 这个问题始终没有得到解决。
有人可以提供任何帮助吗？
