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. > **[Error message by "leaf setup -p swo-wp76\_4.0.3"](https://forum.legato.io/t/error-message-by-leaf-setup-p-swo-wp76-4-0-3/5424)** > > To set up leaf development environment, I send the following command under myWorkspace. leaf setup -p swi-wp76\_4.0.3 WP76\_test But I saw that the following error code (attached picture) in my Ubuntsu PC 16.04 LTS. Error while installing required... what is your leaf version? I don’t see such problem with ubuntu 14 using leaf version 2.1 to download packages. ---

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