Deja dup：尝试在davfs上读取清单时被拒绝
我已经使用DéjàDup创建了几年的备份。 最近它开始失败的消息
Permission denied when trying to read '/duplicity-inc.20161201T072516Z.to.20161202T074205Z.manifest.gpg'. 这似乎是在程序将备份文件写入同一目录后发生的。 文件和包含目录的所有权似乎是正确的：
drwxr-xr-x 2 myuser myuser 68K Dec 2 08:47 dejadup-backup/ -rw-r--r-- 1 myuser myuser 13K Dec 2 08:47 dejadup-backup/duplicity-inc.20161201T072516Z.to.20161202T074205Z.manifest.gpg
目标目录位于通过davfs2安装的远程服务器上。 我的/etc/fstab看起来像这样：
$ cat /etc/fstab ... # mount the fileserver https://fileserver.domain /mnt/fileserver davfs user,_netdev,auto,uid=myuser,gid=myuser 0 0
任何可能导致这种情况的想法以及我如何解决它？
使用DEJA_DUP_DEBUG=1 deja-dup --backup > dejadup.log 2>&1打开调试后，您的dejadup.log文件包含：

再进一步：

所以错误必须在davfs端，你应该在本地调查服务器，没有任何错误。
