Answer 1

存在一个现有包，因此出现以下错误“试图覆盖”。

dpkg：错误处理存档 /var/cache/apt/archives/mongodb-org-mongos_4.2.1_amd64.deb (--unpack)：试图覆盖“/usr/bin/mongos”，它也在包 mongodb-server 中-核心 1:3.6.3-0ubuntu1.1

尝试使用 --force-overwrite 覆盖包

运行命令 sudo dpkg -i --force-all /var/cache/apt/archives/mongodb-org-mongos_4.2.1_amd64.deb

然后运行 ​​install sudo apt-get install -f mongodb-org

Answer 2

sudo apt remove mongo*并重新安装可能会有所帮助。

Answer 3

该错误是由于您的系统已经安装了 mongodb 包，然后尝试安装 mongodb-org。

运行以下命令以删除/卸载现有的已安装 mongo 包。

sudo apt remove mongodb-org
sudo apt purge mongodb-org
sudo apt remove mongodb
sudo apt purge mongodb

您可能还需要一个sudo apt autoremove来删除系统中的常见软件包。

现在尝试安装。 这次你应该没有任何错误地完成它

sudo apt install mongodb-org

启动mongod

sudo systemctl start mongod
sudo systemctl enable mongod

检查 mongod 是否正在运行

sudo service mongod status 

Answer 4

检查 mongod 包是否已经存在。

mongod --version 

或检查 mongod 是否已经在运行

sudo service mongod status

如果已经有 mongod 包，则使用以下命令将其删除并重新安装。

sudo apt remove mongo
sudo apt install mongodb-org
