How can the bios be updated using a bootable USB or via the IPMI?
I would like to install Apache Mesos 1.0.0+ and Marathon ideally from a repository without building the package from source. I am following the following guide from Mesosphere: https://open.mesosphere.com/getting-started/install/ which notes that Ubuntu 16.04 is a supported distribution.
However after running sudo apt-get -y install marathon I get the following output:

The following NEW packages will be installed:

What is the simplest way to install Mesos on Ubuntu 16.04? I've looked at DC/OS however it does not support Ubuntu.
I've installed sensu-core and performed the necessary configurations for sensu-client as per the documentation laid out here for sensu v0.23. I used Windows SC utility to create the Windows service for the Sensu-client and it appears it was done successfully. However I am failing to start the Sensu-client via the Command Prompt and via Services.msc. When trying to force a start using the latter I get Error 216:0xd8.
Any ideas on how to fix this?
I am new to IPMI BMC (always used KVM) and I would like to understand what are the differences between Intel's implementation on IPMI BMC using its RMM4 module and that of Supermicro?
I've read though the documentation and appears pretty standard. Are there any additional security features? I noticed that Supermicro have a mobile app, is there anything similar for Intel?
Are there any other differences (aside from needing to purchase Intel's module separately), benefits or drawbacks between Intel and Supermicro?
