Restore local pacman database

Yesterday, I accidentally removed my local pacman database, ended up not being able to update the system. Following instructions here, I was able to restore part of the local database, probably the Arch-based part. But I am not sure about the Manjaro and Netrunner specific part. I guess I need the original package list of Netrunner Rolling Edition. Where can I find it?

Do you get this when you run sudo pacman -Syu?

:: Synchronizing package databases...
 netrunner is up to date
 core is up to date
 extra is up to date
 community  is up to date
 multilib is up to date

If so and your system is booting with the correct branding (plymouth, sddm. etc.) then you should be fine.

Yep, I get the above together with the following lines:

:: Starting full system upgrade...
 there is nothing to do

Then you should be fine.
