General overview

Deepin 25 represents a major evolution of the Chinese Linux distribution renowned for its exceptional graphical interface. Based on a recent Linux kernel, it integrates the latest version of the DDE (Deepin Desktop Environment) desktop environment, offering smooth animations, extensive customization, and unprecedented visual consistency across native applications. This version focuses on data security and privacy, while simplifying software installation through its improved package manager.

Compatible with modern architectures, Deepin 25 offers a stable experience for everyday users looking for an elegant alternative to traditional operating systems, while benefiting from the software compatibility of the Debian ecosystem. The distribution stands out for its polished design, its native applications developed with the DTK framework, and its particular attention to the user experience.

With the theme “All Advancing, All Renewed” (Everything advances, everything is renewed), Deepin 25 delivers four major innovations and implements more than 1,000 optimizations and fixes. The core file system is mounted read-only for enhanced security, and an improved snapshot mechanism enables automatic restoration in the event of an update or boot failure.

Detailed installation

Method 1: Installation via ISO

The standard installation method uses a bootable ISO image:

  1. Download the Deepin 25 ISO from the official website:
    https://cdimage.deepin.com/releases/25/deepin-desktop-community-25.0-amd64.iso

  2. Create a bootable USB drive with dd or a tool like Etcher:

    sudo dd if=deepin-desktop-community-25.0-amd64.iso of=/dev/sdX bs=4M status=progress && sync

  3. Boot from the USB drive (change the boot order in the BIOS/UEFI)

  4. Select “Install Deepin” from the boot menu

  5. Choose the language, time zone, and keyboard

  6. Configure partitioning (automatic or manual)

  7. Create your user account

  8. Wait for the installation to complete and reboot

Method 2: Virtual Machine

To test Deepin 25 without modifying your system:

  1. Install VirtualBox, VMware, or QEMU/KVM

  2. Create a new VM with at least 4 GB RAM and 40 GB of disk space

  3. Attach the ISO as a virtual drive

  4. Start the VM and follow the installation steps
