Lab 4.3. Install Docker Engine -

rcrook89

I ran into an issue in lab 4.3 and wanted to share it. The commands to add the Docker GPG key and a stable repository led to the apt command throwing the errors below.

After researching this error, I found the updated commands work without issue.

It worked for me when I type a space between "arch=amd64" & "signed-by"

Hi @rcrook89,

Following the correct syntax is critical for commands. Please keep an eye on possible typos that may accidentally end up in commands and instructions typed in the CLI.

Regards,

@chrispokorni It is mostly because "space"s between lines disapear when trying to copy-paste the command from lab pdf to the terminal.
