The instructions here appear to be logical, i've tried both with, and without docker enabled:

Here is the log:

回答1:
The problem was that the repository only contained the 32 bit version of the package. My successful tests were on a 32 bit OS. My failing tests were on Travis and Windows Subsystem for Linux, both of which are 64 bit. Once I uploaded the 64 bit build to the debian repository, it found the package.

Well, the warning is pretty clear:
W: The repository 'https://dl.bintray.com/solvingj/public-deb unstable Release' is not signed.
apt does gpg-verification of each package, in order to make it hard for attackers to replace packages by malicious versions.
Therefore, you should sign the repository, so apt can validate the package authenticity.
An insecure, dangerous and generally bad alternative is to add the --allow-unauthenticated flag:
--allow-unauthenticated
Ignore if packages can't be authenticated and don't prompt about it. This can be useful while working with
local repositories, but is a huge security risk if data authenticity isn't ensured in another way by the user
itself. The usage of the Trusted option for sources.list(5) entries should usually be preferred over this
global override. Configuration Item: APT::Get::AllowUnauthenticated.
Don't use it. You have been warned! Instead sign your repository.
