16055,TLS issues in Ubuntu guest after Windows 10 anniversary update,seb1975,,"I run Ubuntu 14.04 LTS in VirtualBox 5.1.6 on Windows 10. Hyper-V is disabled.

Everything has worked great until the host system was upgraded with KB3181403 (Windows 10 anniversary update).
I already tried the same VM on W8.1 and W7. It works without any issues. 
But the problem can be reproduced on other machines with W10 + KB3181403.

When accessing content via an HTTPS conncetion on W10 with KB3181403 I get the following error in my terminal now:
CODE: SELECT ALL   EXPAND VIEW
unable to access '...': gnutls_handshake() failed: A TLS packet with unexpected length was received.

It doesn't happens with curl.
I have noticed the behavior with my own service application and with apt-get update. Last one fails now for all packages with an HTTPS source.
