I have just met the problem is as below: (in the shell of docker qq container)
oot@978f2bf6e56b:/# apt-get update
Get:1 http://packages.deepin.com/deepin stable InRelease [13.1 kB]
Err:1 http://packages.deepin.com/deepin stable InRelease
Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
Fetched 13.1 kB in 0s (25.8 kB/s)
Reading package lists... Done
E: Failed to fetch http://packages.deepin.com/deepin/dists/stable/InRelease Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
E: Some index files failed to download. They have been ignored, or old ones used instead.
