I upgraded deepin from oem version(huawei matebook 14 linux version) to 15.11, sourcelist contains aliyun and deepin, then it said deepin is trail version and need to activate or import key. The sellor of Huwwei only provided a 16-bit key, but deepin 15.11 asked for a 20-bit key. So I can't activate deepin os. I can't open control center either. THere is no input-method at the dock bar. I can't use Chinese now. Help me, please. Thank you!

I tried to change the sourcelist to lion and upgraded, nothing changed. Then I changed it to camel version, still nothing changed.
