# https://home-store-packages.uniontech.com/appstore/pool/appstore/c/com.tencent.wechat/com.tencent.wechat_1.0.0.236_arm64.deb
# For their safety, UOS mirrors verify client UAs for plain folder view across the whole site, except for exact file path
# home, pro, etc are all just cnames that resolve to app-store-files
# This is just like any other Debian mirrors:
# https://mirrors.tuna.tsinghua.edu.cn/debian/pool/main/b/bash/bash_5.0-4_amd64.deb
# Package list of a release from a debian mirror lives in a different folder like this:
# https://mirrors.tuna.tsinghua.edu.cn/debian/dists/bullseye/main/binary-amd64/Packages.xz
# Substitute the above and we get the following URL (eagle is the most recent release codename):
# https://home-store-packages.uniontech.com/appstore/dists/eagle/appstore/binary-amd64/Packages.gz
