Dear deepin friends, in order to ensure version quality of the next update, we're now launching internal testing seeking participation from all members in this team.
Added the internal test entry in Control Center, by which you can switch the slider to join the internal test.
Connect to the internal source and upgrade the system to the latest edition.
Upgrade method:（The internal test version may be unstable. Please do not use it in production environment）
Change the sources, run in terminal：sudo deepin-editor /etc/apt/sources.list
Paste the following contents to sources.list, then save and exit.
Execute sudo apt-get update && sudo apt-get dist-upgrade command in terminal. After upgrade successful, please reboot your computer.
Test and fill out the questionnaire (https://shimo.im/forms/FBMm8Cel2rk9U1X4/fill) to give feedback on your questions.
Upgrade your kernel to 5.15：sudo apt install linux-image-deepin-stable-amd64 linux-headers-deepin-stable-amd64
Upgrade your kernel to 5.17：sudo apt install linux-image-deepin-experiment-amd64 linux-headers-deepin-experiment-amd64
