mint-build exits with return code 256

[saeed]

Hi all, I'm trying to build the first linux mint project following the official guide. However, when running mint-build in the terminal, I get the following error:

Code: Select all

....
mk-build-deps: Unable to install mintsystem-build-deps at /usr/bin/mk-build-deps line 457.
mk-build-deps: Unable to install all build-dep packages
ERROR: 'sudo DEBIAN_FRONTEND=noninteractive mk-build-deps -i -r -t 'apt-get -y' debian/control' exited with return code 256

Does anyone know how I can resolve this?
Thanks.
