GL-MT300N-V2 missing package ADB

I have firmware.
OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.196.56128-9112198)

I can’t find package ADB in web interface application list or opkg list, how do I install it?

ADB software is not available in our library. You can follow these steps to get it directly from openwrt.

  1. Add the software source manually in **ADMIN->MORE SETTINGS->Advanced->System->Software->Distribution feeds

  2. Click update and find again

Thanks for quick reply, unfortunately hasn’t worked.

I checked feed address was typed correctly by going to website and package details shows up.

Finally worked, thank you for your help
