Is Ambari public server down?

[#1]

I am trying to install Ambari with pubic repositories. At first step, I got:

root@msl-dpe-perf77:/usr/local/Ambari# wget -O /etc/apt/sources.list.d/ambari.list http://public-repo-1.hortonworks.com/ambari/ubuntu16/2.x/updates//ambari.list

I had been using the same process earlier of the week and it works fine. I had tried machine without firewall.

I am almost sure the repos are HA configure I just noticed you have double // after updates in your URL is that correct?a

@Harry Li

Your repo URL is missing the ambari version which should be there between "updates" and "ambari.list" strings ... we see two slashes there. Which repo URL wrong

# wget -O /etc/apt/sources.list.d/ambari.list http://public-repo-1.hortonworks.com/ambari/ubuntu16/2.x/updates//ambari.list

So please check your URL. For Example if you want to download Ambari 2.6.2.2 repo then the URL will be line download

# wget -O /etc/apt/sources.list.d/ambari.list -nv http://public-repo-1.hortonworks.com/ambari/ubuntu16/2.x/updates/2.6.2.2/ambari.list

.

Notice:

/updates/2.6.2.2/ambari.list

There are 2 problems in the Ambari installation document for Ubuntu 16 at https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.0/bk_ambari-installation/content/download_the...

wget -O /etc/apt/sources.list.d/ambari.list http://public-repo-1.hortonworks.com/ambari/ubuntu16/2.x/updates//ambari.list
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD
apt-get update

As both Geoffrey and Jay had pointed out, the first sample command missing version number and document did not instruct to insert that for the execution

For 2nd command to retrieve Linux key, the given format will result in timeout due to the syntax used.

Following syntax will resolve this error
