Unable to nixos-rebuild

Hello,

on my system I am not able to do a rebuild, only the following appeares:

[sebastian@meins:~]$ sudo nixos-rebuild switch --upgrade
unpacking channels...
/run/current-system/sw/bin/nixos-rebuild: line 177: /nix/store/l3nsp9c5h783rh8jviymbzkjf1lbcd9i-nixos-rebuild/bin/nixos-rebuild: Success

Testing with the verbose output does not help too:

Has somebody a clue to me?
