Devmode-engine-rust on Sawtooth running on Ubuntu 16.04 - consensus

Question

I want to install devmode-engine-rust on Sawtooth 1.0.5 running on Ubuntu 16.04. Standard installation using apt-get gives:
sawtooth-devmode-engine-rust :
Depends: libstdc++6 (>= 8.3.0) but 5.4.0-6ubuntu1~16.04.11 is to be installed
Depends: libnorm1 (>= 1.5r6+dfsg1) but it is not installable
Depends: libzmq5 (>= 4.2.5) but 4.1.4-7ubuntu0.1 is to be installed
Depends: libssl1.1 (>= 1.1.1) but it is not installable
Depends: libsodium23 (>= 1.0.16) but it is not installable
Depends: libc6 (>= 2.27) but 2.23-0ubuntu11 is to be installed
Depends: libgcc1 (>= 1:8.3.0) but 1:6.0.1-0ubuntu1 is to be installed

Could not correct this one, so tried to compile from sources. Looks like compilation went OK. Now the question: what are correct directories where to copy compiled binaries and supporting files? Tried the simplest one - put devmode-engine-rust on the path, but that doesn't work.
Alternatively, if anybody knows how to solve the problem with
sudo apt-get install sawtooth-devmode-engine-rust
that would be great, too. Any suggestions on installing sawtooth-devmode-engine-rust are very welcome.
Thank you!
(I did find several stackoverflow articles on that, i.e. adding another depository and doing apt-get update, etc. None of them worked)
P.S. Here is what happens when I start different parts of sawtooth:

If I understand correctly, you are trying to run the consensus engine and connect to the validator. Use Sawtooth version >= 1.1. The 1.0.5 version has the consensus module running inside the validator, so you can't connect it from outside as a separate process. It will be running dev mode consensus by default.
