    Hello, im getting errors:

    1)
    Err [address]
    Cannot initiate the connection to [address] - connect (101: Network is unreachable) [ IP: [ip] ]

    2)
    W: Failed to fetch [address] Cannot initiate the connection to [address][port] ([ip]). - connect (101: Network is unreachable) [IP: [ip] ]

    So do you guys know what can cause that problem ?

    It seems as if the network configuration is wrong on the Ubuntu system. What's in /etc/network/interfaces and /etc/resolv.conf, and what are the outputs of
    Code:
    ifconfig
    and
    Code:
    route -nee
    ?

    What's your router's local IP?

    Yes, you were right! After lookup, i saw that my netmask was wrong. Thanks for pointing me at wrong config.

    now im getting errors like:

    temporary failure resolving 'security.ubuntu.com'

    what the hell can cause that now?

    Note, also when i put on /etc/network/interface --> dhcp, it started to work, but with static ( and correct data for addres, netmask, network, broadcast and getaway, it was all correct it didn't work. )

    interfaces is right now default so it means set to: dhcp!

    and resolv is:

    nameserver 192.168.10.1
    domain TRENDnet
    search TRENDnet

    here it is:


    # This file describes the network interfaces available on your system
    # and how to activate them. For more information, see interfaces(5).

    # The loopback network interface
    auto lo
    iface lo inet loopback

    # The primary network interface
    auto eth0
    iface eth0 inet dhcp

    So your Internet connection and name resolution are both working. Maybe it was just a temporary problem. I think you should try apt again.

    Now its working, but if you are reading my first message, you can see that when i try to use static IP, then it will not work!

    What does your /etc/network/interfaces look like when you use a static IP?
     
  15. q2800

    If i set it to static the interfaces will look like this:

    # This file describes the network interfaces available on your system
    # and how to activate them. For more information, see interfaces(5).

    # The loopback network interface
    auto lo
    iface lo inet loopback

    # The primary network interface
    auto eth0
    iface eth0 inet static
    address 192.168.10.106
    netmask 255.255.255.240
    network 192.168.10.0
    broadcast 192.168.10.255
    gateway 192.168.10.1

    Are the lines after iface eth0 inet static indented? The file must look like this:

    Code:
    # This file describes the network interfaces available on your system
    # and how to activate them. For more information, see interfaces(5).
    
    # The loopback network interface
    auto lo
    iface lo inet loopback
    
    # The primary network interface
    auto eth0
    iface eth0 inet static
      address 192.168.10.106
      netmask 255.255.255.240
      network 192.168.10.0
      broadcast 192.168.10.255
      gateway 192.168.10.1
