Don't Rush After Installing Ubuntu 26.04 LTS! Swiftly Configure Domestic Mirrors (Huawei & Alibaba Cloud APT Sources DEB822 Tutorial)

Tue, 26 May 2026 21:00:00 +0800

TL;DR

Ubuntu 26.04 LTS (Resolute Raccoon) has officially been released. If you have just installed it, the very first thing you should do is replace the default APT sources with fast domestic mirror servers (such as Alibaba Cloud or Huawei Cloud). Note that starting from Ubuntu 24.04, the system has transitioned entirely to the new DEB822 format for APT source configurations (stored in /etc/apt/sources.list.d/ubuntu.sources), making the traditional /etc/apt/sources.list inactive by default.

This tutorial provides a step-by-step guide on how to safely change to Alibaba Cloud and Huawei Cloud mirrors in Ubuntu 26.04 LTS, along with deep troubleshooting analysis for potential pitfalls like dependency conflicts and version codename mismatches.

Stop Using Old Methods! Deploying the Latest Docker CE on Ubuntu 26.04 LTS with Ultra-fast Mirror Setup

Foreword

With the official release of Ubuntu 26.04 LTS (Resolute Raccoon), developers and system administrators worldwide are upgrading their development, testing, and production environments to this long-term support version. However, setting up Docker—the cornerstone of modern containerization and microservices architecture—on a brand-new LTS release can sometimes present unexpected friction.

If you are still relying on legacy commands like apt-get install docker.io, or copy-pasting outdated tutorials meant for Ubuntu 20.04 or 22.04, you are likely to run into issues. These issues range from outdated software packages to APT repository format mismatches (especially with the widespread adoption of the new DEB822 format), or network timeouts when pulling images from container registries in restricted environments.

This article provides a comprehensive, step-by-step, and highly detailed guide to installing Docker Community Edition (Docker CE) on Ubuntu 26.04 LTS. We will delve into modern DEB822 repository configurations, non-root system privilege separation, systemd service tweaks, and advanced network acceleration (both HTTP/HTTPS proxies and private registry mirrors).

In previous episodes, I’ve experimented with Qinglong Panel. However, when trying to pull GitHub repositories, you may encounter network issues leading to pull failures. Regular GitHub file downloads are also extremely slow. So I used the free Cloudflare to build gh-proxy for GitHub acceleration.

I. Prerequisites

You need to prepare a Cloudflare account and a domain name (optional) in advance. For free domains, you can refer to the previous article ‘免费申请注册eu.org二级域名’
