Trying to rollback to php 7.3

[justaslice]

I'm hitting a few roadblocks while trying to rollback php from 7.4 to 7.3 because nextcloud.
In bash
$this->bbcode_second_pass_code('', '$ for pkg in "" "-fpm" "-gd" "-intl"; do sudo pacman -U https://archive.archlinux.org/packages/p/php"$pkg"/php"$pkg"-7.3.12-1-x86_64.pkg.tar.xz; done
$ sudo pacman -U https://archive.archlinux.org/packages/p/php-apcu/php-apcu-5.1.18-1-x86_64.pkg.tar.xz')
Gives me pgp errors.
$this->bbcode_second_pass_code('', ':: Import PGP key 7F2D434B9741E8AC, "Pierre Schmitz <pierre@archlinux.de>"? [Y/n] Y
error: key "7F2D434B9741E8AC" could not be looked up remotely
error: required key missing from keyring
error: '/var/cache/pacman/pkg/php-7.3.12-1-x86_64.pkg.tar.xz': unexpected error
')

Trying to install 7.3 from aur gives me an issue with pgp keys
$this->bbcode_second_pass_code('', 'php-7.3.13.tar.xz ... FAILED (unknown public key D66C9593118BCCB6)
')
And everything I've attempted with gpg and pacman-key gives me a "can't find server" error.

All I want to do is rollback because waiting for nextcloud 18 is starting to feel like waiting for the next Kojima title.

Edit I forgot mention editing `php73/PKGBUILD` arch to aarch64

Wrong forum, you are looking for https://bbs.archlinux.org/

If you trust the source of the packages you can temporarily disable signature checking by setting SigLevel to Never in pacman.conf
