  • Upgrading my Katello-Foreman-Managed RPM build VM to Fedora 32

    Because I have this VM registered to Katello (Foreman plugin) to receive updates (basically as a way of both keeping track of the computers and VMs on my network and also to have a GUI to pulp for caching RPMs), I had to deal with Katello-Agent. The latest RPM in the official Foreman/Katello repos is…

  • Fedora Silverblue as an HTPC Part 3

    Yesterday I mentioned some issues with my Ortek MCE VRC-1100 remote and certain buttons not working. Figured out that in addition to removing the XF…. entries in dconf, also have to remove them in gsettings. Specifically, I had to use the commands: gsettings set org.gnome.settings-daemon.plugins.media-keys stop-static [”] gsettings set org.gnome.settings-daemon.plugins.media-keys play-static [”] gsettings set org.gnome.settings-daemon.plugins.media-keys…

  • Fedora Silverblue as an HTPC Part 2

    One thing to know about Silverblue is that it’s a Gnome environment. I was already running Gnome for the HTPC, but I prefer KDE for my computers usually. When I was installing Silverblue there was no option to go for KDE or anything else. On Silverblue you install via Flatpaks. Any regular installs (ostree instead…

  • Fedora Silverblue as an HTPC Part 1

    Originally I was going to mess around with Silverblue in a VM before considering using it on my HTPC. In theory it sounded like it would work very well – an immutable, rollback-able OS seems like the perfect thing for the one computer that ALWAYS needs to work for less tech-savvy folks in the house.…

  • Recent Fedora 31 and Fedora 32 Upgrades

    Recently upgraded my server to Fedora 31 as the Fedora 30 support window had closed. All I had to do was disable the bat Modular Repo. It wasn’t obvious I needed to do this at first, but I found a bugzilla that covered it. Then everything proceeded. I also updated my main laptop to Fedora…

  • Installing KDE Plasma 5 on CentOS 8

    You can watch the following video. There are also text instructions below the video. (including getting sddm working) I started off with just a boot install of CentOS 8, so I wouldn’t have Gnome or any other unnecessary cruft installed. After installation, I enabled the EPEL repository – latest directions for that are here. After…

  • CentOS 8 on Acer Aspire One D255E

    A little over a year ago, I put CentOS 7 on my Acer Aspire One. We had no idea when RHEL 8 was coming out (turns out just a few months later when I was at the Red Hat Summit, it was the release party for RHEL 8), so 7 went on there. And at…

  • Supermario’s at Fedora 31 Now

    Went ahead and upgraded. Only had to get rid of python2-twitter and an older nvidia package. Other than that it seems to be running relatively smoothly.

  • Attempting a podman play on another VM

    The podman saga continues. The podman equivalent of a docker-compose.yml can be created from a pod with the following command: podman generate kube (name of pod) > (filename).yaml So I did that with the pod that I’d created with an SELinux context. Now it was time to try it on another Fedora 31 VM to…

  • SELinux and Podman

    Last time I messed around with Podman, I finally got things working and had what I think was a pretty good understanding of how to go forward. But in order to get things working, I’d had to turn off SELinux. Now it was time to see what I had to do to make Podman work…

  • Second Followup to Podman and PHPIPAM

    Turns out that on my Fedora 30 VM something got screwed up with the CNI networking (the networking that Podman uses) and instead of pointing to the address that Podman is using according to Cockpit: 10.88.0.1 It’s pointing somewhere else. I found that via iptables -L. Not sure how to fix it, though. When I…

  • Followup to Podman and PHPIpam

    Adding the –name mysql – it wasn’t enough to get the PHPIpam apache container to find the mysql container. They’re in the same pod, but something’s not quite right. So I decided to see if I could modify the config.php by mounting the container and modifying that. # podman mount beautiful_gauss /var/lib/containers/storage/overlay/5a33decc2cfad7e9bda5f9048d94a814267d954e97d5dd7befb057a84367f27a/merged While this allowed…

  • Every once in a while the puerile makes me laugh

    Like these random container names that podman generated: # podman ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES b83a26bb2c5d docker.io/library/mysql:5.6 mysqld 2 minutes ago Up 2 minutes ago 0.0.0.0:8081->80/tcp hungry_wilson f35ec64d3b3c docker.io/pierrecdn/phpipam:latest apache2-foregroun… 2 minutes ago Up 2 minutes ago 0.0.0.0:8081->80/tcp nice_johnson Makes me think perhaps there should be a list of adjectives and…

  • Can Docker and Podman both run on the same machine?

    I’ve been hearing about Podman for a while now – at Red Hat Summit and at various local Red Hat presentations. I’ve seen the slides where the RHEL presenter (it’s always the same guy, but I’m terrible with names – after a bit of research, I think it’s Dan Walsh) asks you to pledge to…

  • Daisy (laptop) upgrade to Fedora 31

    When I tried to upgrade the laptop a couple days ahead of the Tuesday release date, assuming that the sources were as good as gold at that point, the upgrade process complained about the Kdevelop Python plugin and didn’t want to proceed. I figured if this persisted past Tuesday I would just use it as…
