      @benjireis I did all of that... (with sudo first)... same result though.

      Do you want me to start a ticket and a tunnel?

      Peter.

        @pnunn Yeah please open a ticket and a tunnel, I'll have a look.

        Please make sure to add the xoa ssh key to the VMs so I can ssh to the nodes and master.

          Hi!

          I had a similar issue, however i noticed that the k8s VMs created were based on a snapshot of a different VM i had running on the system. So in turn i ended up with a bunch of clones of a completely different VM.

          This VM that the new k8s VMs were based on, was created based off the Debian 10 template. New VMs created with the debian 10 template work fine, however only the k8s recipe ends up basing the image on this existing VM.

            A new version has been released last week or so that solves issues in the recipe.
            Did you encounter any issue with latest xoa?

              Yes currently the issue is with version 5.54.0. Tested about an hour ago

                Latest XOA is 5.55.1, can you try with this version?

                  Looks like that fixed that issue. Now there is an issue with the cloud-config. Seems like gnupg2 is not installed

                      That's weird, I've just ran the recipe and everything went fine.
                      Do you have any network issues explaining the installation problem?

                        This or not enough RAM in the VM, explaining why fork failed to create a new thread…

                          Im also guessing too little RAM. The VMs were started with only 500MB, which i found strange. Any way for me to change this on initialization?

                          Im guessing i could change the Debian 9 template

                            Your VM should have 2G of RAM. Base on our Debian 10 template.
                            This is really weird.

                                Weird, which templates appear in your Hub view?

                                  Just the standard ones:

                                  • Alpine 3.10
                                  • Centos 8.0
                                  • Debian 10
                                  • pfsense 2.4

                                  My XOA has two pools

                                  This issue is similar to the one i had earlier, where the image was being based on a different existing VM, now in this case its the debian 9 template.
                                  I know the debian 10 template works fine as this is what i normally use

                                    I do not understand how the wrong templates can be used by the recipe.

                                      Yes it is quite strange.

                                      This XOA has been in use for some time with a couple of pools added and removed over time, so I may be an edge case here.

                                        Delete the template, maybe it's a previous version 🙂

                                          @olivierlambert I deleted all templates from XOA by going to "Hub" > "Templates" and using the trash icon to remove them. However it still appears that it uses debian 9. I could try to remove all templates from the system via the windows xcp-ng client. However it may be of importance to know that i have never used the debian 9 template before. While using this recipe was the first time i saw it.

                                          I remember trying the k8s recipe about a year ago, maybe that has tainted my setup in some way?

                                            How do you check it's using Debian 9 template exactly?
