apt-get update: (101 Network is Unreachable)

[Joseph Linkous]

It seems almost everyone's gotten this error at one point or another, with
the sheer number of threads about it as evidence. The issue is there's many
causes of and solutions to this problem. Being the noob that I am, I started
opening .conf files here and deleting lines there, and not only have I not
found the solution yet, but now I've got a bunch of files which probably
don't work anymore. There's something to be said about making backups when
you don't know what you're doing, that's for sure.

Since this is my first time setting up a Linux server and I'm not really
making use of it at the moment, I want to run BOINC. However, my screen is
being flooded by errors like this:

Err http://us.archive.ubuntu.com intrepid-updates/main Sources
Cannot initiate the connection to us.archive.ubuntu.com:80 (91.189.88.45).
- connect (101 Network is unreachable) [IP: 91.189.88.45 80]

Cannot initiate the connection to us.archive.ubuntu.com:80 (91.189.88.45). -
connect (101 Network is unreachable) [IP: 91.189.88.45 80]

I was working on it all morning, but I honestly couldn't give you guys a
list of everything I changed to try to get this working.

What are your thoughts, all? I'm pretty new at this, but I feel it will be
worth the effort (and fun!) to learn Ubuntu Server.

(Could it be that you do not have an active internet connection?)

I understand that you are trying to set up an Ubuntu Server, thus no
graphic interface. I understand also that you are quite an experienced
Linux/vim user, brave enough to survive in the terminal world without
Gnome or the like to ease your life.

In case I understood wrong, I think it would be better to begin with the
desktop version and then strip it out of the GDM. It's not the same
thing but it is a lot easier.

The downside (small) to that is that the desktop installs expect your
network connections to be handled by network-manager, and don't start the
connections until you login to the desktop, so you'd then have to
reconfigure the network, anyway.

It sure looks like your network is unreachable. Are you _sure_ you are
connected?

Can you reach anything via a browser?

You're absolutely right, I wasn't connected. I could run nslookup on the
address, but not a ping. Pestilence from the IRC channel walked me through a
few things, then found that /etc/network/interfaces wasn't setup correctly.
After a quick modification, I'm apt-get'ing like a pro.

Thanks for all the help!
