now it's the latest https://github.com/dreemurrs-embedded/Pine64-Arch/releases/download/20251224/archlinux-pinephone-pro-barebone-20251224.img.xz .

My PC hasn't Wi-Fi.

I wanna install Arch Linux ARM Plasma Mobile on my PinePhone Pro https://github.com/dreemurrs-embedded/Pine64-Arch/wiki/Manual-Install-(like-desktop-Arch) , https://github.com/dreemurrs-embedded/Pine64-Arch/wiki/Barebone-Image-Quick-Start#from-a-computer success but the issue:
With Networks (of the PC Arch Linux panel) I can't have both enp5s0 (Ethernet) & enp5s0f3u4 (ssh alarm@10.15.19.82) at the same time, so is it possible?

Otherwise with ssh alarm@10.15.19.82 (no Ethernet) & Wi-Fi:
sudo pacman -Syu : 506 KiB/s...
No USB tethering (is it possible?) (the phone Wi-Fi to the PC): the PC hasn't internet...
so Ethernet seems preferable.
