无法在Ubuntu 20.04上启动MongoDB服务器

我正在（Focal Fossa）上安装最新的MongoDB，它给出了以下错误。我怎样才能修好它

sudo systemctl status mongod

mongod.service - MongoDB Database Server
     Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Fri 2020-08-28 23:40:03 IST; 1min 43s ago

更改“/var/lib/mongodb”目录的所有权对我很有用。 更改所有权的命令：

sudo chown-R mongodb:mongodb/var/lib/mongodb

还要检查您的credschown:无法访问“/var/lib/mongodb”：现在没有显示此错误的文件或目录请访问此文件并遵循解决方案
