Bug Description

I have a Lenovo Yoga 730-13 running Ubuntu 18.04. UEFI.

When booting in secure boot mode the wifi module realtek r8822be is not recognized because it appears the r8822be kernel module is not signed :

Demsg :

2.526831] r8822be: module is from the staging directory, the quality is unknown, you have been warned.
[ 2.527087] r8822be: module verification failed: signature and/or required key missing - tainting kernel

Please advise on a possible fix.
