I'm trying to downgrade to 19.07 in order to fix some issues with my router. This is the imagebuilder command: make image PROFILE="tplink_archer-c6-v2" PACKAGES="ath10k-firmware-qca9888 base-files busybox ca-bundle dnsmasq dropbear firewall4 fstools kmod-ath10k kmod-ath9k kmod-gpio-button-hotplug kmod-nft-offload libc libgcc logd luci mtd netifd nftables opkg ppp procd procd-seccomp procd-ujail swconfig uboot-envtools uci uclient-fetch urandom-seed urngd wpad-mbedtls openvpn-mbedtls luci-theme-bootstrap libustream-mbedtls luci-app-upnp luci-app-openvpn -ath10k-firmware-qca9888-ct -kmod-ath10k-ct umdns irqbalance luci-app-ddns -wpad-basic-mbedtls"
However, it fails with these errors:
