    Hi Sunitha,

    Thanks for your query.

    I see that the error message says "Flex command not found"

    Can you try running the following command and then try to run your script?

    command: sudo apt-get install flex

    I am using Ubuntu 22.04 and getting below error for command: sudo apt-get install flex

    Package flex is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source

    E: Package 'flex' has no installation candidate

    Hi Sunitha,

    I already installed it a while ago, so this is what show on my end on executing the above command.

    flex is already the newest version (2.6.4-6).
    0 upgraded, 0 newly installed, 0 to remove and 48 not upgraded.

    Assuming you are using PSDK, can you please make sure to use Ubuntu 18.04.

    Moreover, looks like the packages are not up to date.

    Can you try running: sudo apt-get update

    And then try rerunning the flex installation command.
