Linux gitlab dosent恢复备份

大家好，我使用gitlab ce 12.0.6，我的操作系统是ubuntu 19.04 我创建备份，但当我想将备份导入gitlab时 我运行这个命令

sudo gitlab-rake gitlab:backup:restore BACKUP=1567495766_2019_09_03_12.0.6_gitlab_backup.tar

它向我显示了以下错误：

rake aborted!
 Permission denied @ dir_chdir - /home/ima/gitbackups/gitlab
/opt/gitlab/embedded/service/gitlab-rails/lib/backup/manager.rb:114:in `chdir'

(See full trace by running task with --trace)

rake中止！

作为一个新手，我到处都搜索过，但没有一个在我的问题上有效。

请帮助我错误的相关部分是：

Permission denied @ dir_chdir - /home/ima/gitbackups/gitlab

此目录应由用户

git

拥有。要更改此设置，请运行

chown-rgit:git/home/ima/gitbackups/gitlab

这还假设上面的目录对所有用户都具有读取/执行权限。也就是说，如果您在路径上运行

ls-la/home/ima/gitbackups

等等，所有这些都应该显示类似于

drwxr-xr-x

，其中末尾有

r-x
