I am on Manjaro plasma.

I did modify pacman.conf and add this :
[home_gambas_3.20_ArchLinux]
Server =
https://download.opensuse.org/repositories/home:/gambas:/3.20/ArchLinux/$arch

In a terminal :
sudo key=$(curl -fsSL
https://download.opensuse.org/repositories/home:gambas:3.20/ArchLinux/$(uname
[1] -m)/home_gambas_3.20_ArchLinux.key) 
curl: (22) The requested URL returned error: 404

What should I do next?
