Unable to update or install packages after fresh install

[froggos]

Hi, how's it going?

This issue's kinda long, I'm sorry:

I'd been having issues with setting up the WiFi on my RPi 3B+, and found that neither the wpa_supplicant, netctl,or wifi-menu options worked. I then decided to hook it up to an Ethernet connection.

From this Ethernet connection, I'm able to $this->bbcode_second_pass_code('', 'ping google.com') and ssh into my main machine. However, I am unable to ssh from my main machine into the RPi. Essentially, I do have internet connection.

I wanted to install the network manager to deal with the WiFi in a more painless way, but I found that I could neither update nor install anything. When I tried $this->bbcode_second_pass_code('', 'pacman -Syu') I got:
$this->bbcode_second_pass_code('', '

')

When I try to install a package, I get very similar looking errors.

I tried a number of solutions, from retrying the $this->bbcode_second_pass_code('', 'pacman init/populate') commands and using $this->bbcode_second_pass_code('', 'pacman -Syyuu') I also downloaded new mirrorlists and commented and uncommented different servers. None of this worked.

I gave up, and tried a fresh installation. Unfortunately, I ran into the exact same errors. What should I do?
