"Ubuntu16.04" resolves a qt installation package (. run file) that cannot be used./Command Execution issues

• When QT is installed on the Ubuntu16.04 system, the installation package is downloaded to the corresponding folder on the Internet, and the next step is to install the command on the terminal.

• Go to the corresponding folder and execute the installation file using the [./qt-opensource-linux-x64-5.9.1.run] command, but you are prompted with the following error:

BASH:./qt-opensource-linux-x64-5.9.1.run:permission denied

• Displays the installation package file with the LS file and finds that the file name is white instead of green, indicating that it is not executable.

at this point, add executable permissions to it , using the following command:

chmod +x./qt-opensource-linux-x64-5.9.1.run

[Note that the specific installation package name is subject to your download.]

• Execute the [./qt-opensource-linux-x64-5.9.1.run] command again to install it properly.
