    QT creator won't run

    In "show applications" I have an icon for Qt Creator .
    Opening new window should start / run it .
    It does not .

    So I decided to o install qtcreator .

    This is what I get in terminal.

    And it ends with this cryptic error

    Media change: please insert the disc labeled
    'Ubuntu 21.04 _Hirsute Hippo_ - Release amd64 (20210420)'
    in the drive '/cdrom/' and press [Enter]


    I do not have crrom , so what are my options to resolve this ?

    Code:
    qr@qr-desktop:~$ sudo apt install qtcreator

    Re: QT creator won't run

    I've added BBCode code tags to your terminal output. Please use code tags when posting terminal output or the contents of config files. This is to preserve columnar formatting and make the output readable. There's a link in my sig for using BBCode code tags if you need it.

    The message about the CDROM is probably because you have the install medium set as a software source. Even if you originally installed with a USB flash drive, software sources shows this as CDROM.

    Assuming you are using standard Ubuntu with the gnome desktop, open Software & Updates, and make sure you are viewing the Ubuntu Software tab. Under "Installable from CD-ROM/DVD", you'll see a checkbox. Untick it. Then run:

    Code:
    sudo apt update
    That should stop the CD-ROM message from appearing.

    The default with any installation is not to have the CD-ROM source ticked. Perhaps you ticked it accidentally or needed to enable it as a source for some other reason. It's worth knowing about this, because it trips up a lot of people. Let us know if that works.
