No you don't. If you use any pre-packaged version of Arch, it's not Arch. If you use a GUI installer, it's not Arch. If you've followed a YouTube tutorial, it's not Arch. If you've opened up this support request, but did not update your system in the last 37 seconds, it's not Arch.
Honestly the installation guide is super easy to follow and well on the shorter side. Installing arch isn’t the arduous test of one’s linux knowledge some make it out to be
:: Synchronizing package databases...
core is up to date
extra is up to date
multilib is up to date
:: Starting full system upgrade...
there is nothing to do
Is the Arch community that bad? I followed the wiki to install it on my Surface Go 2 with secureboot enabled. Is it Arch then? I did update my system in the last 37 seconds, so it's definitely Arch then? Right?
