如何恢复Oracle JDK更新？

Question

I've stopped receiving updates for Oracle JDK for my KUbuntu 14.04 a couple months ago. I have installed and configured it previously according to http://www.webupd8.org/2012/09/install-oracle-java-8-in-ubuntu-via-ppa.html It worked, but now during update I only see errors:

Err https://ppa.launchpad.net trusty/main amd64 Packages
  gnutls_handshake() warning: The server name sent was not recognized
Err https://ppa.launchpad.net trusty/main i386 Packages
  gnutls_handshake() warning: The server name sent was not recognized
W: Failed to fetch https://ppa.launchpad.net/webupd8team/java/ubuntu/dists/trusty/main/binary-amd64/Packages  gnutls_handshake() warning: The server name sent was not recognized

W: Failed to fetch https://ppa.launchpad.net/webupd8team/java/ubuntu/dists/trusty/main/binary-i386/Packages  gnutls_handshake() warning: The server name sent was not recognized

E: Some index files failed to download. They have been ignored, or old ones used instead.

My currently installed version of java is 1.8.0_91.

Content of /etc/apt/sources.list.d/webupd8team-java-trusty.list :

deb https://ppa.launchpad.net/webupd8team/java/ubuntu trusty main

Please, help me to fix this error.
