我安装了全新安装的 18.04 服务器。该软件包redis-server似乎无法安装。我不确定为什么：

$ sudo apt install redis-server
Reading package lists... Done
Building dependency tree

E: Unable to locate package redis-server

该包似乎不存在：

$ sudo apt-cache search redis
miscfiles - Dictionaries and other interesting files
python-redis - Persistent key-value database with network interface (Python library)
resource-agents - Cluster Resource Agents

我已经跑了apt update。我猜它缺少一个软件包存储库，但由于这是一个全新安装，我不确定为什么会丢失一个，或者如何修复它。
