Hi Guys,

I need a little help. I am trying to build the latest Sailfish OS (3.1.0.12) with CM12.1 base for Nexus 5 (I need CM12.1 because of aliendalvik) and I stuck at step '5.1 Checking out CyanogenMod Source' in the HADK Document version 3.0.1.0.

The document says:
run the command: When I run this I get the error "Can't check signature: public key not found":

repo init -u git://github.com/mer-hybris/android.git -b hybris-12.1

fatal: cloning the git-repo repository failed, will remove '.repo/repo'"

Can someone who familiar with the build creation let me know what's wrong and how I can workaround it, please?
Thank you!
