This is on a dreamplug linux server. Configured so that my network starts on 192.168.1.2 and my router is port forwarding ssh to 192.168.1.6 to the server.

    Looks like a network error or DNS error. Can you ping hosts on the Internet by DNS name? How about by IP address? What's in your /etc/resolv.conf file?

  • I can ping ip addresses but not namespaces. I recently got a namespace at no-ip.com

    And is there a nameserver running on the host at 192.168.1.2? Is that your router? Does your router forward DNS requests to an upstream DNS server, like at your ISP? Is THAT working? This is basic debugging, and is not a programming question.

  • yes it is my router which my server is connected to.

Seems to be an issue with your DNS resolver.

Could not resolve 'security.debian.org'
Could not resolve 'ftp.us.debian.org'

etc, etc

It may be helpful to add more details.

What troubleshooting have you tried?

Has apt-get update worked before, and recently stopped working?

Can you ping any of the sites listed in the error?

  • My answer should probably have been a comment. Anyway, what do you mean by "my router is port forwarding ssh to 192.168.1.6 to the server"?

I had to do a lot of searching around on this one.

HTTP seems to have a problem resolving but not FTP. I tried putting in an FTP:// instead of HTTP:// and it worked.

Edit:

/etc/apt/sources.list
deb-src ftp://ftp.uk.debian.org/debian/ wheezy main
deb ftp://ftp.uk.debian.org/debian/ wheezy main
