I am using the schroot mode where there is not network, so gdb can not download 
the debug info.
Is it possible to activate the network from the chroot or should the network be 
activated before starting the build ?

Cheers Jochen

I am not aware of official documentation how to use schroot without network so I don't know how you did that. Instead I would recommend to switch to the unshare backend as that one runs dpkg-buildpackage without network but you get network in the debug shell. And as a reminder, the buildds use sbuild+unshare for testing and unstable.
