I've got a fresh copy of Ubuntu Server 15.04 and installed it via "Easy Install" in VMWare WorkStation 12.
After it installed,i've logged in to my account and tried to install
apache2 with this command:
sudo apt-get install apache2
and got this message:
media change: please insert the disc labled Ubuntu-server 15.04 Vivid Vervet - Release amd64 (20150422) in the drive '/media/cdrom/' and press enter
I'm sure that the internet connection is okay. But how can I avoid this error and install
I have installation ISOl I can use it as CD, also, I have an internet connection to download, and I can
ping google.com successfully.
