15.5.1 is still on the way……not yet released.

Deepin Linux currently has an extreme problem:
1. Newly installed PCs do not migrate to international servers.
That means I set in the system control but in the sources list is always the Chinese main server (very slow in Europe)
2. Even worse: The international mirror servers are no longer updated.
I looked at several servers directly:
eg German alnd ftp.fau.de last update index of ftp://ftp.fau.de/deepin/dists/panda/

Your infrastructure is currently completely down and unfortunately works
not right.

https://bbs.deepin.org/user/101846 ,hi ,can you please check ?

there is something wrong with some mirrors, we will check one by one.

like i have say over and over all mirrors if you check for updates dont matter what mirror you use , not one update is coming in... always say distro is up to date .
i use deepin on my main machines a long time and normaly every day there is a auto clean cachge of package some times more than ones in one day but know (nothing its so dead like a doornail lol

hope you can fix that trouble , ahhh yes there is something wrong ... aida , i have check this i think for 2 or 3 weeks normally i dont say every day but the automatic package wil run if it find something out there know it is so dead that i check it manual but there is on every mirror from europo to whatever fast or medium server nothing to find is like every mirror is in a big dream (winter sleep ) whoehahaha

yes true very true , not france alone , netherlands two , i have check them all out not working , its like they have a big sleep lol

It will take some time .
Thanks for your patient
