NetBSD LeNetBSD1 9.0 NetBSD 9.0 (GENERIC) #0: Fri Feb 14 00:06:28 UTC 2020  mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/amd64/compile/GENERIC amd64
>Description:
I install last week NetBSD 9.0 with pkgin.
I use pkgin after that to install xfce4.
Today, I want to use pkgin and I get :
pkgin: Could not fetch http://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/amd64/9.0/All/pkg_summary.gz
or
Requested list is empty.
There is no more directory name 9.0 so I change to 9.0_current in /usr/pkg/etc/pkgin/repositories.conf.
