Now i am using Panel version 10.2.When i open 'tools and utilities -> updates i get a error like this.

Unable to obtain the latest version of Parallels Products Installer: The required version '3.11.0' was not found on the server. This could happen because of configuration error at the download site. Failed to download the package http://sg2plmirror01.shr.prod.sin2....r-windows/Autoinstaller_3.11.0/ai.exe.md5sum: The requested URL returned error: 404

so help me on this error..

Parallels uses a content distribution network (CDN) to distribute Parallels Plesk Panel packages. This technology uses several cache servers which are distributed across different parts of the Internet. All of the servers share a common domain name, autoinstall.plesk.com, which resolves into different IP addresses, depending on the network segment that a request comes from. Sometimes, one or another server gets out of sync with the main replica and one or a few of its files may go missing.

As possible solution use the main replica of the Parallels Plesk Panel repository until your local CDN server gets in sync with it. To do this, configure the static resolution rule in the file "hosts":
64.131.90.31 autoinstall.plesk.com
