Custom dowload manager for pacman in chroot env

Question

Hello
As this is the place for pacman in general I post here. Feel free to move that thread if you feel it would have a more suitable place.
I'm willing to install Arch on my computer from the live disk of another distro (Tails, based on Debian). I follow these guidelines but an issue is risen because of Tor wich makes resolving DNS less straightforward. Thus I've tried to use the option XferCommand in /etc/pacman.conf in the following way:
XferCommand = /usr/bin/curl --socks5-hostname 127.0.0.1:9050 -C - -f %u > %o
but I just get errors.
# pacman -S arch-install-scripts
warning: database file for 'core' does not exist
warning: database file for 'extra' does not exist
warning: database file for 'community' does not exist
error: target not found: arch-install-scripts
# pacman -Syu
warning: database file for 'core' does not exist
warning: database file for 'extra' does not exist
warning: database file for 'community' does not exist
:: Synchronizing package databases...
sh: /usr/bin/curl: No such file or directory

error: failed to update community (error invoking external downloader)

Would you have any idea to solve this problem? Of course I've checked that /usr/bin contains curl with this line:
XferCommand = ls /usr/bin && /usr/bin/curl --socks5-hostname 127.0.0.1:9050 -C - -f %u > %o
but it seems to be very contradictory:
# pacman -Syu
warning: database file for 'core' does not exist
warning: database file for 'extra' does not exist
warning: database file for 'community' does not exist

Here is what I've done:
ARCHI=$(uname -m)
ARCH_MINI="$HOME/tmp_arch"
mkdir "$ARCH_MINI"
cd "$ARCH_MINI"
alias curl="torsocks curl"
curl -O http://mir.archlinux.fr/~tuxce/chroot/archlinux.chroot.$ARCHI.tgz
tar zxf archlinux.chroot.$ARCHI.tgz
cp /etc/resolv.conf "$ARCH_MINI/etc/"
mount -B /proc "$ARCH_MINI/proc"
mount -B /dev "$ARCH_MINI/dev"
mount -B /sys "$ARCH_MINI/sys"
mount -B /dev/pts "$ARCH_MINI/dev/pts"
ARCH_SYS="$ARCH_MINI/mnt"
mount /dev/sda4 "$ARCH_SYS"
mkdir -p "$ARCH_SYS"/var/{cache/pacman/pkg,lib/pacman} "$ARCH_SYS"/{dev,proc,sys,run,tmp,etc,boot,root,home}
mount -B /proc "$ARCH_SYS/proc"
mount -B /dev "$ARCH_SYS/dev"
mount -B /sys "$ARCH_SYS/sys"
lsblk
mount /dev/sda2 "$ARCH_SYS"/boot
mount /dev/sda1 "$ARCH_SYS"/efi
mount /dev/sda5 "$ARCH_SYS"/home
echo 'PS1="(installation) \w \\$ "' > "$ARCH_SYS/root/.bashrc"
chroot "$ARCH_MINI" /bin/bash
The main issue is I can't use pacman:
(Arch mini) / # pacman -Syu
warning: database file for 'core' does not exist
warning: database file for 'extra' does not exist
warning: database file for 'community' does not exist
:: Synchronizing package databases...
error: failed retrieving file 'core.db' from mir.archlinux.fr : Could not resolve host: mir.archlinux.fr; Unknown error
error: failed to update core (download library error)
error: failed retrieving file 'extra.db' from mir.archlinux.fr : Could not resolve host: mir.archlinux.fr; Unknown error
error: failed to update extra (download library error)
error: failed retrieving file 'community.db' from mir.archlinux.fr : Could not resolve host: mir.archlinux.fr; Unknown error
error: failed to update community (download library error)
error: failed to synchronize any databases
error: failed to init transaction (download library error)
Even if I try to copy curl binary from the host to the chroot and pass it socks option (like in my first message) it says:
/usr/bin/curl: No such file or directory
By default, pacman can't resolve repo name:
(Arch mini) / # pacman -Syu
warning: database file for 'core' does not exist
warning: database file for 'extra' does not exist
warning: database file for 'community' does not exist
:: Synchronizing package databases...
error: failed retrieving file 'core.db' from mir.archlinux.fr : Could not resolve host: mir.archlinux.fr; Unknown error
error: failed to update core (download library error)
error: failed retrieving file 'extra.db' from mir.archlinux.fr : Could not resolve host: mir.archlinux.fr; Unknown error
error: failed to update extra (download library error)
error: failed retrieving file 'community.db' from mir.archlinux.fr : Could not resolve host: mir.archlinux.fr; Unknown error
error: failed to update community (download library error)

If I want to change the adress of the repo in mirrorlist to the resolved IP address
Server = http://91.121.141.57/$repo/os/$arch
it's doesn't work either but says:
(Arch mini) / # pacman -Syu
warning: database file for 'core' does not exist
warning: database file for 'extra' does not exist
warning: database file for 'community' does not exist
