      Debian 10 and Ubuntu 20 works for me only with manual .deb install.
      apt update always fail if repo enabled:

      E: Some index files failed to download. They have been ignored, or old ones used instead.
      

      That still possible to automate with ansible, but very weird.

      Debian 11 & Ubuntu 22 both fine. Didn't notice any problems.
      Probably any RHEL8+ distros should be compatible. Maybe i can check something else.

      @DustinB some soft can't be installed on new distros, but yes, it almost EOL.

        @Tristis-Oris yes I had looked into that last week, and I suspect it could to be related to cert verification in some way, but I'm really not sure what's happening yet.

            I installed tools on next distro:
            just installed and check if OS is recognized, metrics available. Have no idea what else can go wrong if install succeed.

            Alma linux 8.9, Alma linux 9.3, Fedora server 39, OpenSuse Leap 15.5, Oracle 8.9, Oracle 9.3.

                @Tristis-Oris I must say the error message is rather obscure. Can you please open a ticket for this one too?

                  On Fedora 39, you must enable the daemon manually after you install the package. This is probably true on all RPM-based systems.

                  $ sudo systemctl enable --now xen-guest-agent.service
                  

                  I'd be happy to submit a pull request to add that to the RPM package if you will point me at the right repo.

                    @Davidj-0 unfortunately not enabling daemons at first install is the standard behavior in RPM world. I already had a look at changing this for one package, and it turns out to be messy with unforeseen impact, so I gave up with the excuse that admins of RPM-based distros already have to live with this idiosyncrasy anyway.
                    I added this in install instructions in the Gitlab release notes already.

                      IIRC you can just enable and start the service in a %post scriptlet. It's does not conform to Fedora's and RedHat policy for packages included in their repositories, but here the repository is external and we know for sure that the vast majority of users just wants it to be enabled.

                        @stormi that would need to be done only if not upgrading then, or it would interfere with local admin's choice.

                          @yann This is a common condition in scriptlets, yes.

                            @Davidj-0 @Tristis-Oris I started a pull request for this. Seems to work for simple cases, but if you want to shake it in real life that can help!

                              • install over old version. Nothing changed at XO ( waited for about 1-2 min), but after vm reboot it show new tools version.
                              • install over old version, restart tools service systemctl restart xen-guest-agent.service - got new version at XO.
                              • removed old tools first dnf remove xen-guest-agent, reboot host, then install new one.
                              rpm -i xen-guest-agent*
                              Removed "/etc/systemd/system/multi-user.target.wants/xen-guest-agent.service".
                              Created symlink /etc/systemd/system/multi-user.target.wants/xen-guest-agent.service → /usr/lib/systemd/system/xen-guest-agent.service.
                              

                              So it works good. Maybe also add service reload in case of update?

                                Hi @Tristis-Oris,
                                I have the same installation problem as you.
                                When I try to install, it gives me the same error message.
                                How did you solve this?

                                  @Theo main point to avoid such issues without tuning the OS.
                                  easy way - disable selinux.

                                      @yann I can't recall, but does it kick out a notice about that like BSD does? If not, is that a possible addition?

                                        Yes, I agree, disabling SELinux should not be the preferred solution.
                                        It looks more like a bug in the RPM package.

                                            But weird that i succesfully install tools on same distro before.

                                            What version of the RPM package do you have installed?
                                            Is it only xen-guest-agent package that cannot be installed?
