I have an Ubuntu server VM running 18.04 on Proxmox 6.1-7 that I am unable to install Landscape 19.10 on. I follow the steps from the on prem setup page. I have tried with both the --update flag and without. The following code snippet is what Is returned when trying the first step:

username@landscape:~$ sudo add-apt-repository ppa:landscape/19.10
 October 2019 release of Landscape
 More info: https://launchpad.net/~landscape/+archive/ubuntu/19.10
Press [ENTER] to continue or Ctrl-c to cancel adding it.

E: The repository 'http://ppa.launchpad.net/landscape/19.10/ubuntu bionic Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

As you can see it runs into an issue with adding the PPA, citing a certificate issue during the process. If I attempt the next step to install with the command sudo apt install landscape-server-quickstart, I get the following:

username@landscape:~$ sudo apt install landscape-server-quickstart
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package landscape-server-quickstart

If I attempt to go to the url for the package, https://ppa.launchpad.net/landscape/19.10/ubuntu bionic, I am greeted by a certificate error.

closing notes

The server and hypervisor are up to date, both apt and snaps. I have no proxy or IDP/IPS to interrupt the traffic. Is there something I am missing here? Is the certificate bad? Is there a different guide I should follow?

Err:6 https://ppa.launchpad.net/landscape/19.10/ubuntu bionic Release

PPA are accessible through clear http. Exception is for private-PPA which require authentication, but this isn't one of those. Also private PPAs are served from https://private-ppa.launchpad.net, thus likely explaining the SSL error you're getting.

I suggest to:

  1. remove those https ppa entries
  2. re-run sudo add-apt-repository --update ppa:landscape/19.10 so it can add back the ppa (as http, not https) and import the GPG signing key, if that hasn't been done.

  • Thank you for your response! How do I import the GPG key? – strongthany Mar 12 '20 at 16:07
  • Normally, add-apt-repository does it for you. When you add a source manually (say by editing the /etc/apt/sources.list file, you can import a key using apt-key. For this PPA, fetching it would look like sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6E85A86E4652B4E6 , where the last argument corresponds to the fingerprint of the key (or its last digits) – simpoir Mar 12 '20 at 17:30

Add the next record to your /etc/apt/sources.list manually:

deb http://ppa.launchpad.net/landscape/19.10/ubuntu bionic main

Then

sudo apt update && sudo apt install landscape-server-quickstart

  • No dice, I still get the cert issues with this. I've added both the one line and tried with both lines to my sources list. I get the same cert issue/release file missing thing I posted earlier. – strongthany Mar 06 '20 at 23:03
  • have you removed previous source from /etc/apt/sources.list.d/? – Gryu Mar 06 '20 at 23:11
  • Yep, I have nothing in there for landscape. I restored to a previous snapshot of when the server was fully up to date and nothing else was installed. I get the same error. – strongthany Mar 08 '20 at 22:27
