NextTrace 的 Debian / Ubuntu 分发现在已经支持按 flavor 安装。

目前提供 3 个包：
nexttrace：完整版
nexttrace-tiny：精简版，只保留 traceroute
ntr：MTR 专用版

建议统一通过 apt 仓库安装和更新：

curl -fsSL https://github.com/nxtrace/nexttrace-debs/releases/latest/download/nexttrace-archive-keyring.gpg | sudo tee /etc/apt/keyrings/nexttrace.gpg >/dev/null
echo "Types: deb
URIs: https://github.com/nxtrace/nexttrace-debs/releases/latest/download/
Suites: ./
Signed-By: /etc/apt/keyrings/nexttrace.gpg" | sudo tee /etc/apt/sources.list.d/nexttrace.sources >/dev/null
sudo apt update

安装命令：

sudo apt install nexttrace
sudo apt install nexttrace-tiny
sudo apt install ntr

三个包可共存，分别对应：
nexttrace / nexttrace-tiny / ntr
