I have a Ubuntu 16.04 LTS installed on virtual box. I have configured a mail server on it. I have to be able to connect to this server from outside(from host, from another computer, etc). the virtual OS is connected via
NAT. in network setting, I set it on
bridged adaptor, but then I am unable to start virtual box because of this error:
what should I do??
host OS: ubuntu 16.04 LTS
guest OS: ubuntu 16.04 LTS
virtual box version: Version 5.1.38_Ubuntu r122592
