Deja dup：嘗試讀取 davfs 上的清單時權限被拒絕

Deja dup：嘗試讀取 davfs 上的清單時權限被拒絕

我多年來一直使用 Déjà Dup 建立備份。最近它開始失敗並顯示訊息

Permission denied when trying to read ‘/duplicity-inc.20161201T072516Z.to.20161202T074205Z.manifest.gpg’.

這似乎發生了後該程式已將備份檔案寫入同一目錄。文件的所有權和包含的目錄似乎是正確的：

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

目標目錄位於透過 davfs2 安裝的遠端伺服器上。我的/etc/fstab看起來像這樣：

$ cat /etc/fstab 
...
# mount the fileserver
https://fileserver.domain /mnt/fileserver davfs user,_netdev,auto,uid=myuser,gid=myuser 0 0

有什麼想法可能導致此問題以及如何解決它？

使用開啟調試後DEJA_DUP_DEBUG=1 deja-dup --backup > dejadup.log 2>&1，您的德賈杜普日誌文件包含：

DUPLICITY: ERROR 30 EOFError
DUPLICITY: . Traceback (most recent call last):

DUPLICITY: .     raise EOFError
DUPLICITY: . EOFError
DUPLICITY: .

更進一步：

DUPLICITY: DEBUG 1
DUPLICITY: . Backtrace of previous error: Traceback (innermost last):

DUPLICITY: .     None, self.__copy_progress, None)
DUPLICITY: .  Error: g-io-error-quark: Error opening file: Operation not permitted (14)
DUPLICITY: . 

DUPLICITY: WARNING 1
DUPLICITY: . Attempt 1 failed. Error: g-io-error-quark: Error opening file: Operation not permitted (14)

所以錯誤一定是在 davfs 端，你應該調查伺服器，因為本地根本沒有任何問題。
