I was trying to build vyos from source, as suggested earlier (Building VYOS image from source) I compiled the source code of vyatta-quagga and try to build it using debuild -b -us -uc.
The command creates a deb file but when I do a make iso in vyos-build directory, it crashes with the following error:
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)
Could you help me understand why the build crashes?
