我一直在研究这个问题，也读了很多文章。我正试图让它在由 digital ocean 托管的测试服务器上运行。出于某种原因，我的服务器似乎不知从何而来地无法连接到 Mongodb，所以因为这是一个测试，在耗尽这些资源后，我决定删除并重新安装，但是，每当尝试删除 mongodb 时，它都说它不存在：运行后$ sudo apt-get purge mongodb mongodb-server mongodb-server-core mongodb-clients
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package 'mongodb' is not installed, so not removed
Package 'mongodb-clients' is not installed, so not removed
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
mongodb-org : Depends: mongodb-org-server but it is not going to be installed
Depends: mongodb-org-mongos but it is not going to be installed
Depends: mongodb-org-tools but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
所以它说它不存在所以在$ sudo apt-get install mongodb-org我得到之后：
Reading package lists... Done
Building dependency tree
Reading state information... Done
mongodb-org is already the newest version (3.6.17).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
mongodb-org : Depends: mongodb-org-server but it is not going to be installed
Depends: mongodb-org-mongos but it is not going to be installed
Depends: mongodb-org-tools but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
在这两种情况下我都尝试过，apt --fix-broken install但都无济于事。
$ mongo当我打字时
MongoDB shell version v3.6.17

我读到过关于揭露、启用或任何类型的 mongodb 交互的信息：

我正在执行与之前访问数据库相同的所有操作......不知道发生了什么......谢谢你们。

看来你通过添加额外的内容弄乱了你的存储库mongodb-org存储库。
尝试注释掉它的源代码/etc/apt/sources.list.d/mongodb-org-4.2.list或类似的文件。
然后做sudo apt update && sudo apt install -f
然后再试一次：sudo apt install mongodb等等。
