Thanks for you reply.
This is a screenshot when I open the Appstore.
The titles and descriptions of the applications are in Chinese.
First I had a problem that I couldn't open the Control Center. (It was an earlier version than 15.10, I guess 15.4)
Then I have runned this command:
Code:
sudo apt-get install dde-control-center
After that I updated the system (with apt-update / apt-upgrade)
End then the problem occurs with the Chinese language.
I have now executed the command you suggested:
Code:
sudo apt-get update && sudo apt-get dist-upgrade -y
Now it's working, language is English again!
Thanks!
