Thanks for sharing. Use setupTermuxArch.sh --help for instructions how to set the mirror manually. Evidently http://os.archlinuxarm.org/ is handing off an inactive mirror in your geographic location. Running the script again hoping you will get a better mirror next time is also a possible solution.

I also encountered this issue, from multiple attempts I ended up with the following invalid URIs in the output:

Downloading ArchLinuxARM-aarch64-latest.tar.gz from http://au.mirror.archlinuxarm..
Downloading ArchLinuxARM-aarch64-latest.tar.gz from http://sg.mirror.archlinuxarm..
Downloading ArchLinuxARM-aarch64-latest.tar.gz from .archlinuxarm.org/.

I can't tell at which stage the URI is getting mangled, but when I run

curl -v "http://os.archlinuxarm.org/"

The Location header seems to be okay on multiple separate attempts.
e.g.
< Location: http://au.mirror.archlinuxarm.org/
< Location: http://sg.mirror.archlinuxarm.org/

Using http://au.mirror.archlinuxarm.org/ as the mirror in setupTermuxArchConfigs.sh resulted in a successful installation.

@JoshuaWebb Thanks for the update. Glad to hear that you found a mirror that works. Some of the mirrors near me are more reliable than others. I guess that's what mirrors are for. See https://archlinuxarm.org/about/mirrors for contact information.
