Wal-e:无法推送备份-权限错误

Question

当我们尝试使用wal-e推送备份时，会出现以下错误：

PermissionError: [Errno 1] Operation not permitted

目前尚不清楚fcntl调用可能导致PermissionError的原因。

PostgreSQL版本：9.6，Python:3.5，Wal-e:1.1.1(也尝试过1.0.3和1.1.0(。

它以前一直在工作，但在某个时候停止了工作(没有任何明显的变化(。

好吧，我玩游戏迟到了。看见https://github.com/wal-e/wal-e/issues/270

我通过修补wal-e来解决这个问题。
