我只是想尽快测试一下.所以我运行了一个docker容器，我想判断我运行的是哪个版本:
$ docker run -it ubuntu
root@471bdb08b11a:/# lsb_release -a
bash: lsb_release: command not found
root@471bdb08b11a:/#
所以我试着安装它(suggested here个):
root@471bdb08b11a:/# apt install lsb_release
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package lsb_release
root@471bdb08b11a:/#
有人知道为什么这不管用吗？
