每次我尝试通过ftps://Nautilus（Ubuntu 文件）连接时，都会收到以下消息：
The site's identity can't be verified:
The certificate does not match the identity of the site.
Certificate information:
Identity:[...]
Verified by: [...]
Expires: [...]
Fingerprint (...):[...]
Are you really sure you would like to continue?
[No][Yes]
每次尝试连接时都会收到此消息。
如何比较或确认此消息指纹来验证一下并且不再收到该消息？
