[Bug 1860461] Re: libgnutls30 3.6.11.1-2ubuntu2 (Ubuntu 20.04) breaks pulseui client with error "Error performing TLS handshake: The Diffie-Hellman prime sent by the server is not acceptable (not long enough)."

[Sebastien Bacher]

The issue there seems to be with the servers not up to current standard
and what gnutls enforce, is there anything that needs to be done from
the online accounts or evolution?

Bug description:
  After upgrade to 20.04 package libgnutls30 broke pulseUI VPN client
  with the following error:

  "Error performing TLS handshake: The Diffie-Hellman prime sent by the
  server is not acceptable (not long enough)."

  I had to revert the package to the 19.10 version (3.6.9-5ubuntu1) and
  to install 19.10 dependency libhogweed4 3.4.1-1 to fix it.
