Unabe to open a web browser and connect to the internet on Virtual box using Ubuntu 14.04

omci · 07-04-2017, 05:23 PM

I freshly installed virtual machine Ubuntu 14.04 on virtual box. I am trying to open a web browser on the virtual machine using the command: sensible-browser
This produced the following error:

Code:

ConfigBase::load: Unable to open /home/robotics/.config/terminator/config ([Errno 2] No such file or directory: '/home/robotics/.config/terminator/config')
/usr/share/terminator/terminatorlib/terminator.py:87: Warning: Attempt to add property GnomeProgram::sm-connect after class was initialised

** (x-terminal-emulator:2003): WARNING **: Binding '<Shift><Control><Alt>a' failed!

Any help will be greatly appreciated.

What network type is selected for Ubuntu in VirtualBox--->Settings--->Network--->Attached to. (If it's Host Only, change it to NAT and test. Host Only does not allow the VM access to the big wide world.)

Also, what is the output of

Code:

ifconfig                or
ip addr                       and
traceroute google.com
tracefoute 8.8.8.8

being sure to surround it with "code" tags, which become available when you click the "Go Advanced" button at the bottom of the "compose post" window.

In my network settings, I have enabled two Adapters. One is attached to "NAT" and other is "Host-only Adapter".
This is my output for ifconfig

Your tracerout does seem to be reaching Google.com in some form.

I suggest disabling the "host only" adapter and retesting.

As my signature says, test one thing at a time.

I disabled "host only". After reboot upon running sensible-browser. I get the same error as before. Can you elaborate if it was upto you, how would you setup such a network. Also what adpter type complies with NAT?
Note: I am using a VM with an .ova file provided by my institute with ubuntu 14.04 and ros-indigo.
