I have installed 4
ubuntu servers on a virtual machine. same installation procedure where i set the proxy, domain, ip during the installation. it appears that 2 of the machine have no issues at all. both ping and apt-get. but for some unknown reason the other 2 can ping anything including
us.archive.ubuntu.com but can't do
sudo apt-get update .
so all of them have the file
What i've noticed here is that there is no port number for any of them.Even with that 2 servers still can update via
for now there is no http_proxy set in either
Can anyone help you? thank you.
