E: Unable to locate package vim

报错信息

在docker的nginx容器中,向安装vim,结果报错

root@7365d9c2c7ea:/etc/nginx# apt-get install vim
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package vim

解决方案

这种方法确实比较慢,
但是如果有兴趣看下面的心酸经历,
就会明白为啥这么慢我还采取这种解决方案 . . .

apt-get update

apt-get install apt-file

apt-file update

# now finally this will work !!!
apt-get install vim

//(这个公钥根据提示来写的)

gpg --keyserver keyserver.ubuntu.com --recv YYYYYYYYYYYYYYYY

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 'YYYYYYYYYYYYYYYY'

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 'XXXXXXXXXXXXXXXX'

错误套娃...

死循环了?

更换源,需要"apt-get update",
"apt-get update"需要"apt-key adv --...",
但是"apt-key adv --..."需要更换源 . . . ???

算了,还是去找第一个错误"E: Unable to locate package vim"的解决方案吧 . . .

直接FQ,第一条就成功解决...(就是慢一点)

apt-get update

apt-get install apt-file

apt-file update

apt-get install vim     # now finally this will work !!!
