Recently, deepin community team has received feedback from users that there were some third-party commercial applications and redistribution authorization issues in the official repository.
We responded immediately and carried out actions such as cleaning, removal, and migration, saving a lot of repository space (189GB). Deepin 15 repository (https://packages.deepin.com/) will be replaced with the official repository (https:/ /community-packages.deepin.com). Global mirror sites can also sync the latest deepin 20 repository and ISO images. Details are as follows:
