I just installed my first Ubuntu Server (12.04) instance and immediately ran into the following problems:
updatefails (see below)
ifconfigproduces peculiar IP addresses starting with
10.x.x.xand my router does not see the server at all in its "Attached Devices" page (its a consumer grade Netgear)
When I run
apt-get I get 50+ of the following errors:
Failed to fetch <some-http-url>. Temporary failure resolving <blah>.ubuntu.com
I read up on this error for 12.04, and found some similar posts on this forum and on server fault that recommended going into
/etc/resolv.conf and adding an entry:
To my surprise, I found that
/etc/resolv.conf was a symlink pointing to somewhere else and I had to delete it first, then create a new one with the entry indicated above.
I restarted the server and tried running
apt-get again, same results.
How do I start diagnosing the problem (I'm a relatively new Linux/Ubuntu user)?
Additional details that may help:
- This is actually a virtual machine running as a VirtualBox guest OS
- The physical host that is running this VM is my laptop which has a wireless connection; I'm wondering if (somehow) the laptop is getting the network wirelessly, but perhaps either the VBox VM and/or the Ubuntu server OS isn't configured for wireless and so nothing is "getting through"?
Thanks in advance for any pointers!
Here is a snapshot of my VM's Network settings (only Adapter 1 has any information populating its fields, so I assume my VM has only 1 adapter):
Here is the output when I run
ifconfig from the terminal:
And here is the output when I run
