uyuni hostnames
by Huber, Peter 14 Jan '21

14 Jan '21

The following situation. I want to bootstrap a server with an underscore in his hostname. The host can not by found, but this must be wrong. Nslookup, ssh connects to this host are possible. Is this a bug, or why can I not use underscores in hostnames? Kind regards, Peter

bootstrap
by Huber, Peter 08 Jan '21

08 Jan '21

Hi, I want to bootstrap a client via private / public-key, but I got an error message: Load key "/srv/susemanager/salt/salt_ssh/temp_bootstrap_keys/boostrapKeyTmp-0b697b75-4f8c-4df3-b4eb-86a6b45d7ec8": invalid format I guess this could be a CR/LF problem, because the private key is stored on a windows machine. When I copy the tmp file before it is deleted I can see, that there is a CR/LF and so it differs from the linux file. Could this be the problem? cat -e <temp_bootstrap_keys/boostrapKeyTmp-0b697b75-4f8c-4df3-b4eb-86a6b45d7ec8 -----BEGIN OPENSSH PRIVATE KEY-----^M$ b3BlbnNzaC1rZXktdjEAAAAACmFlczI1Ni1jdHIAAAAGYmNyeXB0AAAAGAAAABA6i5cmFq^M$ cat -e <original file on linux -----BEGIN OPENSSH PRIVATE KEY-----$ b3BlbnNzaC1rZXktdjEAAAAACmFlczI1Ni1jdHIAAAAGYmNyeXB0AAAAGAAAABA6i5cmFq$ Is it possible to use a private key, stored somewhere on the uyuni server? Kind regards Peter

Hello I'm about to create the appointments for the next months and I was wondering if last Friday of the month, 4pm CET is still the best time. What are your thoughts? Would you prefer some other week of the month, day or time? Thank you Pau Garcia Quiles SUSE Manager Product Owner & Technical Project Manager Phone: +34 91 048 7632 SUSE Software Solutions Spain

Can I have an AIX Salt Minion connect to a Uyuni Salt Master?
by Luiz Da Silva 08 Jan '21

08 Jan '21

Hello list, first post. Given that IBM provides Salt packages for AIX [1], including salt-minion and salt-ssh, would AIX work as a Salt minion (or Salt client as some Uyuni docs sometimes refer to) that connects to a Uyuni Salt master? The reason why I'm asking this is because, on Saltstack, AIX usage is restricted to Saltstack Enterprise. Even downloading the minion package for AIX from Saltstack is restricted. [2] So, I was wondering, would there be any usage related or legal related restrictions regarding running Salt minion on AIX, using the IBM provided packages, and a Uyuni Salt Master? Thank you for your patience and time.

GPG check
by Huber, Peter 07 Jan '21

07 Jan '21

Hello and a happy new year, I have a problem and I don't know how to solve this. - latest Uyuni installation, openSuse 15.2 - I added a software channel *disabled* "enable GPG checking", added a repo, *disabled* "has signed metadata". - when I try to sync this channel, I get "RepoMDError: Cannot access repository. Maybe repository GPG keys are not imported", but I disabled GPG checking.. Is this a bug, or is my config wrong? Kind regards Peter

2020: Retrospective for an exceptional year for Uyuni
by Julio González Gil 04 Jan '21

04 Jan '21

Dear users and contributors, Now that 2020 is coming to an end, I'd like to take a quick look back at what year was for Uyuni. During 2020 we saw the community grow in numbers, not just in terms of users, but also in terms of active contributors. Now we have people helping with the translations, the documentation, the code itself (be it bugfixing or even new features), and helping other fellow users at the mailing lists or Gitter. Here are some highlights of what we all accomplished during the last 12 months: - We now release each month or two months: 8 releases this year (versus 1 in 2019 and 2 in 2018). - Since May 2020, we have been holding monthly Uyuni Community Hours meetings, with presentations both from the main contributor (SUSE) and the community. - We started a YouTube channel and populated it with videos on how to use Uyuni, translate it, test it and analyze its performance [1]. - We moved our chat from IRC to Gitter [2] - Mailing lists were moved to the new system [3] (kudos to the openSUSE Heroes team!) - Uyuni can now be translated, and that brought a lot of contributors that already did an impressive job in a number of languages. - Support for new OS as clients: CentOS/RHEL 8 (including ppc64le for CentOS 7/8), Ubuntu 20.04, Oracle Linux 6/7/8 and Debian 9/10. - A lot of improvements in monitoring with Prometheus such as: new exporters (and supported OSs), autodiscovery, federation and reverse proxy. - Grafana, which can be used (among other things) to show the status of the prometheus monotoring. - Performance improvements for repository syncing. - Uyuni Hub: allows management of several Uyuni Servers from a central one. - Recurring actions. - Usability improvements: automated database schema upgrade, autogeneration of bootstrap repositories, UI icons for child channel synchronization status, etc - New formulas and improved formulas (cpu mitigations, prometheus federation, prometheus exporters, Uyuni Hub...). - Single sign-on (SSO). - WebUI themes. - Server and Proxy were updated to openSUSE Leap 15.2, that brought salt 3000 and PostgreSQL 12 - Yomi: new installer framework for openSUSE And SUSE Linux Enterprise Linux, with formulas and forms for easy use - A port of the Server to CentOS 8 was started Keep in mind this is just a brief hightlight. The release notes [2] contain so many changes and improvements that we cannot possibly list all of them here. This was only possible thanks to the combined effort of all people from the community, SUSE and openSUSE, and we can all be proud of the results. Let me wish you all the best for the upcoming year 2021, for your personal endeavours, and for your work at Uyuni, and for all your loved ones. Keep up the good work, and remember to have a lot of fun!

Changing Centos 8 Linux servers to Centos 8 Stream breaks Uyuni functionality.
by Simon Avery 16 Dec '20

16 Dec '20

Hi Following Redhat's announcement last week, I've moved three systems from Centos 8 Linux to centos 8 Stream. I've added the Stream repos to Uyuni and switched channels to them, then followed the instructions at https://centos.org/distro-faq/ (As Uyuni doesn't have a uyuni-tools repo for Stream, I used the same Centos 8 Linux repo) The operation went successfully on the clients and all seemed good. However, it later emerged some of Uyuni's salt functionality has been lost on these clients. What's okay: Remote commands still work, and all scheduled instructions to these servers are picked up as before. What's not okay: 1. Highstate won't apply. This also breaks repos when re-running the bootstrap command: "curl -Sks https://{URL}/pub/bootstrap/bootstrap-c8.sh<https://%7bURL%7d/pub/bootstrap/bootstrap-c8.sh> | /bin/bash" As part of the script, existing repos are disabled, and any existing susemanager:channels.repo file is removed. Normally, this file is recreated when Highstate is applied, but this now fails. (Ditto when applying via Uyuni's webui) Error: Error: Could not parse state file. Please check YAML syntax. On server, /var/log/salt/minion logs show things like; 2020-12-16 11:50:41,871 [salt.state :3636][CRITICAL][36037] Rendering SLS 'base:services.salt-minion' failed: Jinja variable 'salt.utils.templates.AliasedLoader object' has no attribute 'pkg.list_repos' 2. When running "Update Package List" via the webui (Server page: Software -> Packages) An unexpected error has occurred. Please check the server logs. We see 2020-12-15 14:29:41,653 [salt.utils.decorators:636 ][WARNING ][7610] The function "module.run" is using its deprecated version and will expire in version "Sodium". 2020-12-15 14:29:46,319 [salt.state :323 ][ERROR ][7610] Module function pkg.info_installed is not available System info: /etc/centos-release: CentOS Stream release 8 salt-minion -version: salt-minion 3000 Uyuni master is 2020-11 yum repolist: repo id repo name susemanager:c8s-powertools CentOS 8-stream Powertools susemanager:c8s_appstream Centos 8-stream Appstream susemanager:centos8stream_x86_64 Centos 8 Stream (x86_64) susemanager:uyuni_client_stream Uyuni Client Tools for CentOS 8 (x86_64) Stream To me, these two problems look linked, and I'm guessing that the Stream migration process has 'lost' a Salt module for package and repo management. My knowledge of salt is not good enough to diagnose this issue, and it's proved difficult to google a way to success despite spending too much time on it yesterday. Can someone please help?

Bootstrap not copying ssomanager on OL7

When I try to install the bootstrap, everything seems to work, right up until the end and it gets to the registering phase when suddenly it goes: REGISTRATION ------------ * registering ./bootstrap-ol7.sh: line 832: /etc/salt/minion.d/susemanager.conf: No such file or directory ./bootstrap-ol7.sh: line 833: /etc/salt/minion.d/susemanager.conf: No such file or directory ./bootstrap-ol7.sh: line 834: /etc/salt/minion.d/susemanager.conf: No such file or directory ./bootstrap-ol7.sh: line 835: /etc/salt/minion.d/susemanager.conf: No such file or directory ./bootstrap-ol7.sh: line 836: /etc/salt/minion.d/susemanager.conf: No such file or directory ./bootstrap-ol7.sh: line 837: /etc/salt/minion.d/susemanager.conf: No such file or directory ./bootstrap-ol7.sh: line 840: /etc/salt/minion.d/susemanager.conf: No such file or directory * removing TLS certificate used for bootstrap (will be re-added via salt state) * starting salt daemon and enabling it during boot Created symlink from /etc/systemd/system/multi-user.target.wants/salt-minion.service to /usr/lib/systemd/system/salt-minion.service. i have verified the minion.d folder exists but the susemanager.conf file has not been copied.
