dnf is not working on qemu-arm-static chroot environment

[Chanho Park]

Hi,

I want to execute dnf command on fedora-arm version 22 with
qemu-arm-static chroot environment.
Unfortunately, dnf command was failed with below errors:

cachedir: /var/cache/dnf
DNF version: 1.1.6
qemu: Unsupported syscall: 374
Failed to synchronize cache for repo 'rpmfusion-free-updates' from
'http://mirrors.rpmfusion.org/mirrorlist?repo=free-fedora-updates-released-22&arch=arm':
Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve
host name for
http://mirrors.rpmfusion.org/mirrorlist?repo=free-fedora-updates-released...
[Could not resolve host: mirrors.rpmfusion.org], disabling.
Error: Failed to synchronize cache for repo 'fedora' from

[Could not resolve host: mirrors.fedoraproject.org]

It seems the qemu-arm-static could be recognized on 'arm' not 'armhfp'.
Is there any ways to run dnf command on the qemu chroot environment?

Full work history:
sudo cp /usr/bin/qemu-arm-static arm_root/usr/bin
sudo mount -o rbind /proc arm_root/proc
sudo mount -o rbind /sys arm_root/sys
sudo mount -o rbind /dev arm_root/dev
sudo mount -o rbind /dev/pts arm_root/dev/pts

sudo chroot arm_root

dnf update

I had similar issue. I've tried to install the most recent ca-certificates*.rpm
manually. No success. Having no other idea how to manage the situation, I decided to
implement very ugly and brutal workaround. Namely, I have added temporarily
'sslverify=0' to '/etc/dnf/dnf.conf'. I'm still looking for the
solution that addresses the real root cause.

I have revealed the root cause of my issue. That was a time synchronization failure.
Having the system time set to 1970-01-01, I had the setup outside the certificates'
validation period. The proper chrony setup ceased the problem.
