Hai this is manoj,
I liked the deepin interface, so i have installed it on my PC ( i've removed ubuntu 16.04).
The problem is that i am not able to update it.

so when i type

sudo apt-get update

I am getting the error as follows:

Err:1 http://packages.deepin.com/deepin panda InRelease
403 Forbidden [IP: 94.130.49.186 80]
Reading package lists... Done
E: Failed to fetch http://packages.deepin.com/deepin/dists/panda/InRelease 403 Forbidden [IP: 94.130.49.186 80]
E: The repository 'http://packages.deepin.com/deepin panda InRelease' is no longer signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

So how can i move on to solve this problem.
thank you

That mirror is down. Go here: https://www.deepin.org/en/mirrors/packages/ to find a mirror near you, click the 'http' (blue) link, go to the deepin directory, copy the URL from the url box in the browser, paste it into /etc/apt/sources.list in the same line and position as the offending url, delete the offending URL, and try your update again.
