Thanks for your interest! We have two test repos you can add:
- Stable testing (close to release):
deb https://ci.deepin.com/repo/deepin/deepin-community/stable/ crimson main commercial community - Dev testing (bleeding‑edge, unstable):
deb https://ci.deepin.com/repo/deepin/deepin-community/testing/ unstable/crimson main commercial community
You can edit /etc/apt/sources.list with sudo nano /etc/apt/sources.list or put them in a separate .list file.
Just a heads‑up: these are really unstable, and the community won't provide support for any breakage caused by them – but you already know that 😉
Also, regarding deepin 25.2 – it's still under active development and testing. The version number will only be updated right before the official release, so even with these test sources, you won't see "25.2" in the system version for now.

How to fix grub boot menu that has disappeared? 
Hello Deepin Community & Developers,
I am currently running Deepin ci 25.2.0 and I want to test the latest bleeding-edge updates, features, and experimental packages, even if they are unstable.
Could anyone please provide me with the correct and official developer repositories/mirrors to add to my
/etc/apt/sources.listor/etc/apt/sources.list.d/?I am fully aware of the risks of using unstable branches and know how to handle system rollbacks if needed. I just want to stay up to date with the latest code changes.
Thank you in advance for your help!
