我正在尝试使用(以root身份运行(安装mongodb 4.4：apt install -y mongodb-org
但后来我得到了
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
mongodb-org : Depends: mongodb-org-mongos but it is not going to be installed
mongodb-org-tools : Depends: mongodb-database-tools but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
所以我用apt --fix-broken install得到：

E: Sub-process /usr/bin/dpkg returned an error code (1)
因此，我尝试使用：apt remove mongodb-org删除mongodb，并得到：

请参阅Mongodb没有从4.2正确更新到4.4。
删除所有已安装的mongodb包，然后安装4.4包。
使用dpkg -l |grep mongodb查找已安装的。
