In openjdk:11.0.7-jre-slim's container can not use apt-get update

I use following cmd:

[root@cm-wsb-c16m64d200-1 ~]# docker pull openjdk:11.0.7-jre-slim
docker run -it docker.io/openjdk bash
[root@cm-wsb-c16m64d200-1 ~]# docker run -it docker.io/openjdk:11.0.7-jre-slim bash
root@e482bece621a:/# apt-get update

Seems to be a connection problem, so i change /etc/apt/sources.list, and run again:

root@e482bece621a:/# apt-get update

I google this problem, use apt-key adv --keyserver keyserver.ubuntu.com --recv-keys　3B4FE6ACC0B21F32 can slove this problem.

BUT 

root@e482bece621a:/# apt-key adv --keyserver keyserver.ubuntu.com --recv-keys　3B4FE6ACC0B21F32
E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation

I need apt-get install gnupg!!!! This is an endless loop!!! please tell me, how do I use apt-get update after changing the /etc/apt/sources.list???

Network is unreachable would be an issue on the host's end

You could also try asking over at the Docker Community Forums, Docker Community Slack, or Stack Overflow. Since these repos aren't really a user-help forum
