    I've been developing on my iMac and now I've downloaded Ubuntu 20.04 which I have set-up in Oracle VirtualBox. I have downloaded qt-unified-linux-x64-4.0.1-1-online.run, several times actually, but when I try to run it from Ubuntu by clicking on the file I get an error dialog containing:

    Could Not Display "qt-unified-linux-x64-4.0.1-1-online.run"
    
    There is no application installed for "executable" files.  Do you want to search for an application to open this file?
    

    This was downloaded automatically from:
    https://www.qt.io/download-thank-you

    I've clicked the button "Search in Software", nothing happens.

    Kind Regards,
    Sy

      @SPlatten Not really Qt related. You should ask this on the forum related to the broken Debian you use.

      My guess would be that downloaded file doesn't have exec permission. Righ-click on the file, [Properties], "Allow file execution" or similar.
      Alternatively from the console: "chmod +x qt-unified-linux-x64-4.0.1-1-online.run"

      That should fix your issue but I would also allow for the risk that this system is more broken than usual.

      For more information please re-read.

      Kind Regards,
      Artur

        Hi,

        From memory, by default the file is not executable.

        You have to use the terminal and do a chmod +x "qt-unified-linux-x64-4.0.1-1-online.run and then either call it directly from there or double click on it.

          @SPlatten You have to set execution permission(https://wiki.qt.io/Install_Qt_5_on_Ubuntu)

          It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth. (Sherlock Holmes)

            This is unrelated to the distribution used, the file just has no execution permission which is fine in itself.

              Hi
              Its default on ubuntu.
              https://help.ubuntu.com/community/InstallingRunPackage

              As else it would be very Windows alike to allow to run anything pr default:)

                  @SGaist In theory, yes. Downloaded files should always have execution bit missing. But this is ubuntu, you never know if it will behave like a proper Linux should.

                    Not sure what you mean: it behaves exactly like it should, executable bit is not set for downloaded files.

                        I use Ubuntu and/or Debian since many years, it works as it should.
                        Most of the time system error occurred when I force something what the system did not allow ;)

                            @KroMignon Bashing might be a bit of a strong word but I detest *buntu deeply. Having to work with those over the years I become very cautious as it tends to break in the least suitable moments. Maybe for purely desktop use it is ok, I admit to lack of experience in that regard. In every other aspect it is... Full of surprises, let's say. Of course, still better than most other distros.

                                @SPlatten Try to start it from the terminal and see whether there are any errors.
                                Also try to start it with "-noload all" parameter to see whether it makes a difference.

                                  Obviously from the list above there are prerequisites required that are not present. Is there a guide on how to get up and running? I was following an online guide by Qt, but I didn't think I had to manually go through the huge list of downloads?

                                    @artwaw , @jsulm , dam it, Virtualbox isn't new and still seems buggy as hell, Shared Clipboard & Drag'n'Drop both set to Bidirectional, neither work.

                                    I've opened a terminal and typed in:

                                    Did you install VirtualBox extensions?
                                    I use Ubuntu 20.04 in a VirtualBox VM on Windows7 and Windows10 host and copy/past or shared clipboard just work.

                                    I hope you did not install Qt as administrator on your Ubuntu VM?

                                      It could be the macOS variant of Oracle VirtualBox. The user I'm using on Ubuntu is a standard user not super user.
