debsig: Origin Signature check failed

[Hendrik Tews <tews@tcs.inf.tu-dresden.de>]

Hi,

I am trying to install amd64 into a chroot. base-config failed at
some state because of a missing /proc filesystem. After fixing
that I run base-config again, but it did not install any
packages. Then I tried tried tasksel and dselect. 

Now dselect gives me lots of errors like 

    dpkg: error processing /var/cache/apt/archives/mtr-tiny_0.58-1.0.0.1.pure64_amd64.deb (--unpack):
     Verification on package /var/cache/apt/archives/mtr-tiny_0.58-1.0.0.1.pure64_amd64.deb failed!
    Authenticating /var/cache/apt/archives/mutt_1.5.6-20040523+2_amd64.deb ...
    debsig: Origin Signature check failed. This deb might not be signed.

Whats wrong here?

Bye,

Hendrik
