What to do next ?

  • OK, things are getting serious

    This is what I get when trying to verify my current installation:

    f@f-SATA:~$ sudo apt install qtcreator
    [sudo] password for f: 
    Reading package lists... Done
    Building dependency tree       
    Reading state information... Done
    qtcreator is already the newest version (3.5.1+dfsg-2ubuntu2).
    The following packages were automatically installed and are no longer required:
      linux-headers-4.15.0-129 linux-headers-4.15.0-129-generic
      linux-image-4.15.0-129-generic linux-modules-4.15.0-129-generic
    Use 'sudo apt autoremove' to remove them.
    0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.


    Am I correct to say
    I have Qt version 5.5.2

    and QtCreator version 3.5.1

    To confuse things more - this version of my Ubuntu OS DOES OT have "Maintenance tool"

    I have used the latest "Qt installer" ( on another OS) and it appears that it installed Qt version 5.15.2. Nothing about QtCreator.

    I do not want to repeat the "install" on this version of OS and have a same issue.

    My questions are :

    1. Is my version of QtCreator outdated ?
      If so
    2. Should I just unistall it and do another
      $ sudo apt install qtcreator
      and hope it will work installing NEWER version of QtCreator?

    ( I would like to install another copy of QtCreator in different folder - but not sure how to specify the folder )

    1. Should I just forget messing with QtCreator, use current "installer" and go from there ?

    There's no reason for your Linux distribution to provide the Maintenance Tool that comes with the online installer as they already provide the infrastructure to get their package.

    1. yes it's way outdated since the current version is 4.14
    2. no, you distribution does not provide a more reverent version. If you want the latest and greatest, then use the online installer.

    Note that the online installer does not fiddle with your system installation, therefore is you do not use proper path when starting Qt Creator from the command line, you will get the version you installed using apt.

    And again: Qt5.15 does not support the ancient Ubuntu 16.04 as already written here. Upgrade your OS!

    OK, it is a matter "who is on first" .
    I did try Ubuntu 18 and did not see any good reason just to have a different desktop GUI. Simply not interested in GUI changes.

    Just installed clean 16 and did

    sudo apt install qtcreator

    NO examples and no "autodetect kits " .

    and I know what the reply is going to be - use "installer"
    .. heading that way .

    Funky part when I originally used the "ubuntu extended install " process it worked just fine - examples and kit .

    Should I blame the latest fiasco on Ubuntu? Why not...

    BTW to use "installer" I have to have "account" - which I have established
    long time ago...

    It's not a question of GUI changes, it's also a question of running a 5 years old distribution to do development work with recent frameworks and tools. You are running a distribution that will reach end of life in three months if you did install the LTS version. If you did it then it has already ended.

    You are not required to use bleeding edge stuff but keeping your distribution up to date is a good habit especially with regard to security and bug fixes as well.

    If you choose to stick with Ubuntu 16.04 that is up to you. But then expect to use the versions of Qt/Qt Creator which were supported on that OS release, not necessarily the latest versions now. @Christian-Ehrlicher previously referred you to, which I'm sure you read, stating that the oldest version of Ubuntu supported for Qt 5.15, for example, is Ubuntu 18.04. So if you try to install/use it in 16.04 there may be problems....
