自足常乐

环境debian9，安装mongod，碰到软件包依赖问题，跳不过去

26 wget https://repo.percona.com/apt/percona-release_0.1-4.$(lsb_release -sc)_all.deb
27 dpkg -i percona-release_0.1-4.$(lsb_release -sc)_all.deb
28 apt-get update
29 apt-get install percona-server-mongodb-34
常规操作，按照上面执行后，提示下面信息：

root@sd-113255:~# apt-get install percona-server-mongodb-34
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:
percona-server-mongodb-34 : Depends: percona-server-mongodb-34-mongos (= 3.4.22-2.20.stretch) but 3.4.21-2.19.stretch is to be installed

Depends: percona-server-mongodb-34-server (= 3.4.22-2.20.stretch) but 3.4.21-2.19.stretch is to be installed
Depends: percona-server-mongodb-34-tools (= 3.4.22-2.20.stretch) but it is not going to be installed
percona-server-mongodb-34-dbg : Depends: percona-server-mongodb-34 (= 3.4.21-2.19.stretch) but 3.4.22-2.20.stretch is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

debian环境方便的是命令行在线更新，按照提示执行“apt –fix-broken install”，解决问题。
