You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
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).
我尝试安装 ppa 版本（旧文档），现在我认为我有两个版本存在永远无法删除的循环依赖关系。
