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

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 +SDJOURNALTHAT 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.ascI 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 directory0 -
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.

hello everyone
i am not able to install docker with second method in lab 4.3.
whenever i am running 'sudo apt install -y apt-transport-https ca-certificates curlgnupg-agent software-properties-common'

Hi @saumya043,
You have a typo in your command. There should be a space between
curl
andgnupg
