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
