I can connect to the Internet OK and have done an update(apt-get update) but cannot install anything because when I type "apt-get Install foo" it times out and I get the message "cannot connect to archive" I've tried pinging the URLs in the sources list but that doesn't work.In Firefox, I can get to the repository.

Here is the contents of /etc/apt/sources.list
Note: I deleted the http part of the URLs because I was not allowed to have URl's in the meassage.

I can ping google.com and it's ip address.I can't ping the above URL's but they work in a browser. I cant get email to connect either but Internet browsing via Firefox seems perfect. This is really odd!
I am running Xubuntu dapper Beta 2(had same problem with Ubuntu dapper Fl 6).Any help would be greatly appreciated.
Bye ...richag77

Ok ..
apt-get update worked, but you can't ping the repos?
That's a bit odd, isn't it?


Can we get more details about the network? And how exactly does
"the internet works" work? Which activities CAN you do?

In Firefox, under Edit > Preferences > General > Connection Settings, is there a proxy set?

And that is relevant to apt-get how?

Or did you just mean to ask him whether he's using a
proxy at all?


Cheers,
Tink

I don't know what Robbbert meant. But I can say this, if he's using a proxy that may be the problem he's having for apt-get is not aware of that yet.

I've looked at that and there's a "Direct connection to Internet", no proxy. This is a hard one. By the way, Red Hat has no problem getting to its application repository.All this stuff has happened since they put in a new router/modem at work.(Netcomm adsl2+ modem/router)

What do the admins say (those who control that router)?

You could do some
and post the outputs for the working / not working URLs - and hope on someone being proficient enough to interprete them.

BTW, I had to install traceroute as it didn't came with the base distribution. Should be a standard tool though?!
