Installation leaf and build mangOH software

I’d like to use Bluetooth on the mangoH. If I understood it is better to use Linux, right? I followed Appendix A of the mangOH Yellow Getting Started Guide.

But when it comes to :
$ leaf setup -p mangOH-yellow-wp77xx_0.2.3
I get error:
error during sync step for swi-verify-aptdeps.1.6.191122 (command return 100)

Could you explain me what to do please?

seems same issue as this one.

what is your leaf version?

I don’t see such problem with ubuntu 14 using leaf version 2.1 to download packages.

I have leaf version 2.1.3

Maybe you can try the latest version of LEAF.
BTW, are you using ubuntu PC?

Yes I am using Ubuntu 20.

I have an error when setup environment using "leaf setup -p " :

E: The repository ‘http://ppa.launchpad.net/danielrichter2007/grub-customizer/ubuntu/pool/main/g/grub-customizer/’ does not a release file
N: Updating from such a repository can’t be done securely, and is therefore disabled by default
N: See apt-secure(8) manpage for repository creation and user configuration details

I think this it more a Linux issue. If you dont know, do not care. Thank you.

The issue is that my ubuntu version is too recent. Don’t you have a installation procedure for ubuntu 20?

I only tried on ubuntu 14 16 and 18, all are ok.
