How to join the internal test channel -- [Remember, use the latest release version, not V23]

The current method of adding internal testing is the same as before. You need to manually add internal testing source information in the terminal. Methods as below:

Step 1. Backup system source:

Execute the following command, the original system source will be backed up as the sources.list_bak file.

The correct way to join the closed beta:
① Upgrade the system to 20.7.1

②Open the internal test channel: [Control Center]》【Update】》【Update Settings】》【Internal Test Source Update】

③ Follow the guidelines to complete the opening of the internal test channel

Note: The original method of adding internal testing sources (manually adding internal testing sources) can no longer receive internal testing updates, please clear the manually added internal testing source information in time.

Step 2. Add the internal test source:

Directly download the sources.list file below and replace it in the /etc/apt directory:

sources.list: https://pan.baidu.com/s/1RjfU4TKLEd3Mob9At-FAJw Extraction code: zimo

Execute the following command in the terminal:

sudo apt-get update && sudo apt-get dist-upgrade (may need to logout and restart)

Note：

Linux5.15 kernel installation: sudo apt install linux-image-deepin-stable-amd64 linux-headers-deepin-stable-amd64

Linux5.17 kernel installation: sudo apt install linux-image-deepin-experiment-amd64 linux-headers-deepin-experiment-amd64

Take the test and fill out the questionnaire to give feedback on your questions.

Internal testing rules (important)

1. Keep the system version upgraded to the latest internal beta version to avoid problems caused by inconsistent versions.
2. When a problem is found, the feedback form can be used for feedback as soon as possible
3. After entering the internal testing group, please change the name to the user name of the deepin forum, so that we can contact you to communicate the specific details of the problem (Note: it is the user name, hover over the avatar in the upper right corner and click to enter the "User Center", copy "Username" information).

Notes for feedback on internal testing issues

1. When reporting bugs, you must fill in the correct deepin forum username to ensure that it is consistent with the group nickname of the internal test group, so that we can communicate in a timely manner;
2. It is necessary to specify the preconditions, that is, what operations are done when the phenomenon occurs that may lead to the problem, and the problem must be omitted;
3. The detailed reproduction steps need to be written so that the official personnel can reproduce the verification problem as soon as possible;
4. It is necessary to clearly explain the expected results and the actual results, to avoid inconsistencies in the understanding of different personnel, and no ambiguous descriptions are allowed;
5. It is best to provide screenshots and screen recordings (static screenshots, mp4, gif are all acceptable), mainly to clearly feedback the problem;
6. If there is no problem, it is necessary to provide system log information to facilitate R&D for positioning and troubleshooting;
7. You can submit the severity and priority of the problem according to the actual impact on yourself;
8. For questions about demand, you can directly go to the forum for feedback: bbs.deepin.org.
