Flair installation problem with deb file and flair repository

Dear expert,
I am sorry to disturb you. When I update my flair through the .deb file or flair repository, I met problem as the picture described: the .deb file can not be downloaded and the repository can not be visited. I tried many times, and can not solve the problem.
Installation with the source file also met probem. Could you help me with the installation problem? Thank you!

 Best regards,
 Yours Jiangfeng
