Problems compiling my linux kernel with bitbake

I have a problem when I try to build my own kernel images for the twr-LS1021. I tried it with the virtual box and by installing the sdk on a native system (Ubuntu 14.04 32 Bit). I tried to setup my development system by downloading the sdk images (v1.7 and v2.0) and also by installing it as shown in the following link.


4. Create SDK — TWR-LS1021A A documentation


When I try to build my kernel, with hob or from the command line, I get the following error. In the command line I tried the commands "bitbake fsl-image-core" and "bitbake virtual/kernel". It is always the same error.

The failure happens independent from the environment where my system is running. In one environment I hav to use a proxy, the other network works without a proxy.


Can anyone explain me what the reason for this problem is?


Thanks for your help and kind regards,
