Container setup failed on mac

I am trying to set up my container. I keep getting this error after a while (ca. 1000s):

executor failed running [/bin/sh -c echo "Server=$REPO_DATE/\$repo/os/\$arch" > /etc/pacman.d/mirrorlist && 	echo ${PACKAGES} && 	pacman-key --init && 	pacman -Syu --noconfirm --needed ${PACKAGES} && 	pacman -Scc --noconfirm && 	ln -sf /usr/share/zoneinfo/$TIMEZONE_REGION/$TIMEZONE_CITY /etc/localtime && 	echo "Setting up host" && 	echo "$HOSTNAME"> /etc/hostname]: exit code: 1


Thanking you in advance

This looks like a network issue.
Did you possibly have a network outage while it was running?

You should probably simply try again. If it fails again, make sure your internet connection is working properly.
