Public bug reported:
### Ubuntu Release
root@<server name>:~# lsb_release -rd
Description: Ubuntu 14.04.5 LTS
Release: 14.04
root@<server name>:~#
### Expected Behaviors
Trusty’s version of apt should be able to pull updates from an internal
mirror using the HTTPS protocol and a SHA256 certificate (please check
the 2nd link at the end of this description)
Note: Using the same configuration on Ubuntu Xenial works.
### Actual Behavior
Apt error out with the error: gnutls_handshake() failed: The signature
algorithm is not supported.
### Package Information
Im not sure if the problem is actually with apt of with a library (I’m
including libgnutls26 info as well)
