    Hi @etofran810,

    Linux environments are case sensitive, so installing runc would require it to be spelled with all lower case runc.

    For Docker and rkt you can always check the official documentation and the installation guides of latest releases:

    https://docs.docker.com/install/linux/docker-ce/ubuntu/

    https://github.com/rkt/rkt/blob/master/Documentation/trying-out-rkt.md#trying-out-rkt

    Regards,
    -Chris

    Regarding Lab 4.5 Install RKT, I must be missing something. I tried going through the steps in the lab and got a number of wget-and-other based errors. I went to the RKT site and was able to use the following:

    wget https://github.com/rkt/rkt/releases/download/v1.30.0/rkt-v1.30.0.tar.gz

    With success, but from that point on, the lab instructions in the lab got me nowhere. And then I discovered another installation method:

    $ sudo apt install rkt

    result:

    $ rkt version
    rkt Version: 1.30.0
    appc Version: 0.8.11
    Go Version: go1.13.5
    Go OS/Arch: linux/amd64
    Features: -TPM +SDJOURNAL

    THAT was successful. If the intent of the lab was to install rkt, what were the following commands for? Was there another lesson to be learned besides a simple install?

    $ gpg —recv-key 18AD5014C99EF7E3BA5F6CE950BDD3E0FC8A365E
    $ gpg --verify rkt_1.30.0-1_amd64.deb.asc

    I won't go into wget.

    The gpg -verify... command failed with

    gpg: can't open 'rkt_1.30.0-1_amd64.deb.asc': No such file or directory
    gpg: verify signatures failed: No such file or directory

    Hi @rogerh,

    It seems that some of the rkt secure install artifacts have been removed from the official repository, and cause a few steps to no longer work as expected. But as you discovered yourself, it can still be installed and used as a runtime for testing purposes.

    Hi @saumya043,

    You have a typo in your command. There should be a space between curl and gnupg
