    After many installations, I have:

    ./qt-opensource-linux-x86-5.5.1.run -h
Usage: ./qt-opensource-linux-x86-5.5.1.run [options] Key=Value

Options:
  -h, --help                           Displays this help.
  --version                            Displays version information.
  --framework-version                  Displays the version of the Qt Installer
                                       Framework.
  -v, --verbose                        Verbose mode. Prints out more
                                       information.
  --proxy                              Use system proxy on Windows and Linux.
                                       This option has no effect on OS X.
  --script <file>                      Execute the script given as argument.
  --checkupdates                       Check for updates and return an XML
                                       description.
  --updater                            Start application in updater mode.
  --manage-packages                    Start application in package manager
                                       mode.
  --no-force-installations             Allow deselecting components that are
                                       marked as forced.
  --show-virtual-components            Show virtual components in installer and
                                       package manager.
  --logging-rules <rules>              Enables logging according to passed
                                       rules. Comma separated logging rules have
                                       the following syntax:
                                       loggingCategory=true/false. Passing empty
                                       logging rules enables all logging
                                       categories. The following rules enable a
                                       single category:
                                       ifw.*=false,ifw.category=true The
                                       following logging categories are
                                       available:
                                       ifw.componentChecker
                                       ifw.resources
                                       ifw.translations
  --create-local-repository            Create a local repository inside the
                                       installation directory. This option has
                                       no effect on online installers.
  --addRepository <URI,...>            Add a local or remote repository to the
                                       list of user defined repositories.
  --addTempRepository <URI,...>        Add a local or remote repository to the
                                       list of temporary available repositories.
  --setTempRepository <URI,...>        Set a local or remote repository as
                                       temporary repository, it is the only one
                                       used during fetch.
                                       Note: URI must be prefixed with the
                                       protocol, i.e. file:///, https://,
                                       http:// or ftp://.
  --startserver <mode,socketname,key>  Starts the application as headless
                                       process waiting for commands to execute.
                                       Mode can be DEBUG or PRODUCTION. In DEBUG
                                       mode, the option values can be
                                       omitted.Note: The server will not
                                       shutdown on his own, you need to quit the
                                       process by hand.
  --startclient <socketname,key>       Starts the application to debug the
                                       client-server communication. If a value
                                       is omitted, the client will use a default
                                       instead. Note: The server process is not
                                       started by the client application in that
                                       case, you need to start it on your own.

Arguments:
  Key=Value                            Key Value pair to be set.

    How could I Install?

    I don't understand whether/how you say you have got it to run now.

    If you still need help identifying missing 32-bit libraries I would try following https://superuser.com/a/908417, copying ldd and changing it along the lines of

    Changing this line to RTLDLIST="/lib32/ld-linux.so.2 /lib64/..." immediately fixed the problem.

        I do not understand what you don't understand!? That post says to (copy and) make a change to the ldd script file, and then run that changed copy against your executable.

              Well at least that gives you an idea of what libraries you will want. I was hoping the (changed) ldd might give you similar on the new system.

              Anyway, at this point maybe you have gotten all of those dependencies for the new system? If all you are left with now is SSL library errors I think those might only be dynamically loaded as needed at runtime, you might be close. You need an SSL expert (for Qt 5.5/Ubuntu 16) to tell you what you need to do for that, I don't know....

                I finally got it. Simply run the following commands:

                sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libstdc++6:i386

                I also installed the following packages from apt

                sudo apt-get install qtbase5-dev:i386 qtmultimedia5-dev:i386

                Now everything is working perfectly.
