August 31, 2021 | By the+gnu+linux+evangelist.

Installing

  1. 2. Enabling Qt4 Repository

    Add Qt4 PPA Repository for Ubuntu GNU/Linux

    Enabling Qt4 Repo for Ubuntu
  2. 3. Installing Qt4

    Then to Install Qt4 in Ubuntu
    Simply run:

    sudo apt install qt4-default

    Authenticate with the User’s Admin Pass.
    If Got “User is Not in Sudoers file” then see: How to Enable sudo.
    Next to make it fixed and so integrate it definitely into the System:

    sudo apt-mark manual qt4-default qt4-qmake qtcore4-l10n libllvm9 libmng2 libodbc1 libqt4-dbus libqt4-declarative libqt4-designer libqt4-dev libqt4-dev-bin libqt4-help libqt4-network libqt4-opengl libqt4-opengl-dev libqt4-qt3support libqt4-script libqt4-scripttools libqt4-sql libqt4-sql-odbc libqt4-svg libqt4-test libqt4-xml libqt4-xmlpatterns libqtdbus4 libqtgui4 qdbus qt4-linguist-tools
  3. 4. Reinstalling Qt5

    Now you have to Reinstall Qt5
    This because the default Ubuntu setup suppose only one version is enough:

    sudo apt install qt5-default
  4. 5. Testing Qt4

    Finally, to Test Qt4 Setup
    On Command Line play:

    qmake-qt4 -v
  5. So Now I’m truly Happy if My Guide could Help you to Install Qt4 on Elementary OS 6!
