I've local repository along this url this define in the ambari-server :
I don't know why the repo was changed to public repo when i'll add new host like this picture.
thanks for your help
it looks like you still use the public repo. You need to select the local repo by click the radio button in your previous version/repository selection page.
can you tell your ambari version and see if there is any fonts issues in your machine where you are accessing ambari URL.
Also check the user who runs the ambai-server.
Try to enable the debug properites (log4j.rootLogger=DEBUG) in the file /etc/ambari-server/conf/log4j.properties and see if you could find anything in the ambari-server log.
You can check your in browser ---> developer tools if there is any error when loading the page.
