There are several modes in which you can connect to internet inside from a virtual machine. Easiest is using NAT.

Select your Ubuntu virtual machine in virtual box manager and go to settings. Navigate to Network and select NAT as shown in the screenshot.

When you open Ubuntu go to Network Connection and go to Wired tab and select your connection and Edit. Use Automatic (DHCP) under IPv4 Settings. Also you can check the connect automatically. Then your system will be connected to network every time you open it.

  • is your host network functioning properly? Was the connection established at all in guest? how did you check? usually it should connect if you would able to follow the instruction properly. try restarting the virtual machine and check all the settings once. we need some more info to help you to troubleshoot.

This same problem was solved for me by changing a previously selected setting. When I originally set up VB I configured it to use a wireless connection. But then wireless for me became unavailable because of my situation, but I had forgotten that I needed to change the setting in VB to use a wired connection instead.

I don't know if this reflects your situation, but here are the steps for changing connection type:

Open VB, go to Settings, Network, Adapter 1, "Name", choose connection type.

I also had the problem that I couldn't access the Internet from my Ubuntu VM. I forgot that on the host machine (Windows 10 x64) still, an OpenVPN connection was active.

I closed OpenVPN on the Windows machine and it worked again.
