我一直在尝试从源（https://access.crunchydata.com/documentation/pgbackrest/2.00/pdf/backrest.pdf）在 linux（ubuntu）上的 postgres 中增量加载数据，而我正在尝试创建一个节我我收到以下错误。

由于我是 Linux 平台的新手，所以花了 2 天以上的时间，我无法解决它！

sudo -u postgres pgbackrest --stanza=demo --log-level-console=info stanza-create
2019-10-03 16:16:22.730 P00   INFO: stanza-create command begin 2.16: --log-level-console=info --pg1-path=/var/lib/postgresql/11/demo --repo1-path=/var/lib/pgbackrest --stanza=demo

ERROR: [050]: unable to acquire lock on file '/tmp/pgbackrest/demo-archive.lock': Permission denied
       HINT: does the user running pgBackRest have permissions on the '/tmp/pgbackrest/demo-archive.lock' file?
2019-10-03 16:16:22.730 P00   INFO: stanza-create command end: aborted with exception [050]

出现这种情况的原因是什么以及如何解决？

我遇到了同样的问题，只需删除临时文件夹及其文件即可解决

sudo rm -r pgbackrest/

它对我有用。另一种可能的解决方案是删除临时文件夹和节并重新创建节。
