MATE 1.20 test build for CentOS 7 available
by Greg Bailey 14 Oct '21

14 Oct '21

Hi everyone, There's been discussions in the past about updating MATE RPMs in EPEL-7: https://bugzilla.redhat.com/show_bug.cgi?id=1436260 https://lists.centos.org/pipermail/centos/2019-August/173154.html (and lots of others...) As a proof-of-concept, I've written some scripts that clone specific commits from the Fedora master branches, and then runs a tool to re-apply RPM scriptlets that are required by EL7 but removed from the Fedora .spec files. The scripts are available at: https://github.com/gebailey/mate-rpms/tree/master/1.20/el7 There's also instructions there if you want to try upgrading to MATE 1.20 w/o rebuilding them yourself. If these packages work for others, perhaps we can revisit the idea of updating the epel7 branches of the Fedora git repos and submitting an official update. There's nothing here (yet) about building MATE 1.22 (which might require a newer gcc for EL7), or building anything on CentOS 8, but thought the CentOS 7 users might find this helpful. -Greg

Transition test report going from CentOS8 to Debian 10.
by Lamar Owen 06 Aug '21

06 Aug '21

Sorry for the length.... I'm posting this here since this particular transition has been mentioned on-list as one possibility for a path forward for current CentOS Linux users. AlmaLinux, the Developer Subscription RHEL, Rocky, CentOS Stream, Springdale, upgrading to full RHEL; all these are also possibilities, too, and all have different strengths and weaknesses. The transition to Debian has a lot of strengths, including a long track-record of support (even if the support time for a particular release is shorter), a fully-open development model with no 'corporate overlord' that I know of, a large set of supported packages, and a huge community of developers and users. For the CentOS user the main weakness is having to learn a few areas of difference in the way the system is setup and maintained; of course, if a ten-year 'stable' timeframe is really that important to you the lack of that is also a weakness. So, last week I transitioned, as a test of sorts, my working CentOS 8 main laptop to Debian 10. I kept a complete backup of the C8 install should I wish to go back to it, and installed Buster to a new mSATA SSD, but ported the two SATA drives (Dell Precision M6700 - has an mSATA slot plus two SATA bays) straight over after making full backups. I posted a pretty complete rundown on the scientific linux users mailing list, so I won't recap it all here. The bottom line was the the transition was not any more difficult, really, than moving from CentOS 7 to CentOS 8. The software versions in Buster are pretty close to what is in CentOS 8, although I have yet to need any third-party repository (PPA) for anything I've needed to install. All the packages I have worked with so far have worked fine with a little bit of massaging. These include commercial (and costly) software such as Harrison Consoles' Mixbus32C, Qoppa's PDFStudio2019 Professional, and others. So if you were to decide that this is the route for you to take, it does work and I found it to be not nearly as hard as I had thought it might be. If you install GNOME 3 you get GNOME 3; it feels pretty much the same as a non-Classic CentOS GNOME 3, just with a different set of extensions installed by default. That's on the workstation. On the server side, I'm evaluating Proxmox for the virtualization solution, and so far I'm finding it to be a pretty easy migration. I'm using the 'non-subscription' repository, so this is a no-cost option. Even getting the box registered to our EMC Clariion SAN was relatively easy; EMC provides the Unisphere Server Utility for Linux x64 in RPM form; the latest I have is "ServerUtil-Linux-64-x86-en_US-1.0.55.1.0044-1.x86_64.rpm" (which is fairly old, but I did say Clariion arrays, so they're pretty old, too). Debian has provided the 'alien' tool for some time; after installing alien, a simple 'alien -i ServerUtil-Linux-64-x86-en_US-1.0.55.1.0044-1.x86_64.rpm' installed the EMC RPM in the correct place. Proxmox already included everything that serverutilcli requires; on a plain Buster install I had to install dm-multipath and the device mapper libraries and tools before serverutilcli would find the arrays; but it ran just like it did on CentOS 8 (and 7). I haven't decided whether to stay on Debian or not; too early to tell. I have time to test and evaluate. My CentOS 7 installs aren't goin anywhere, though, at least until late 2023. And I've registered for a Developer subscription of RHEL so that I can properly evaluate that option, too. This is the beauty of open source: we have OPTIONS.

Will there be newer versions of Centos? We have heard rumors that version 8 will be the last one. We are concerned with using an OS that will loose support in the future. Thank you.

Fwd: Pre-announcement of an ISC DHCP security issue scheduled for disclosure 26 May 2021
by Kenneth Porter 07 Jun '21

-------- Forwarded Message -------- Subject: Pre-announcement of an ISC DHCP security issue scheduled for disclosure 26 May 2021 Date: Fri, 21 May 2021 11:44:19 -0800 From: Michael McNally <mcnally(a)isc.org> To: dhcp-announce(a)lists.isc.org Hello, dhcp-announce list subscribers, It has been a while since our last post to this list. Since the last time we posted news of a new release of ISC DHCP, Internet Systems Consortium has adopted a practice of pre-announcing expected security disclosures in order to give operators who use our products a little advance warning and planning time. For that reason, I am writing you today to let you know that a vulnerability in ISC DHCP will be publicly announced next week on Wednesday, 26 May 2021. Further details about that vulnerability will be publicly disclosed next week, and new releases of ISC DHCP that correct the vulnerability will be made available at that time. It is our hope that this pre-announcement will aid DHCP operators in preparing for that disclosure when it occurs. Yours sincerely, Michael McNally (writing for ISC Security Officer) _______________________________________________ dhcp-announce mailing list dhcp-announce(a)lists.isc.org https://lists.isc.org/mailman/listinfo/dhcp-announce

kmod removal
by Emmett Culley 29 May '21

29 May '21

Sometime ago I thought I needed kmod-wl to support a new wireless card. Turns out I didn't need to do that. Now I'd like to remove kmod entirely. But when I try I get this: [root@ws1 etc]# dnf remove kmod Error: Problem: The operation would result in removing the following protected packages: systemd-udev (try to add '--skip-broken' to skip uninstallable packages) I am sure I don't want to remove systemd-udev, so I am a loss. I did disable akmods: systemctl disable akmods But I still see that kmod-wl is built each time the kernal is updated. Any suggestions where I can find out how to remove kmod. Note that searching the internet only brings me info on removing kmod-nvidia, and mostly on ubuntu, and they are no help because mostly what they discuss is how get back to neuveau. Even docs I've found that discuss how to install kmod on CentOS say nothing about removal. Emmett

non-functioning printer
by Michael Hennebry 20 May '21

20 May '21

In an attempt to diagnose a friend's HP Deskjet D1420, I'm running a Centos 6.10 LiveDVD. The readily visible symptom is that it will accept a job and claim to be printing it, but nothing ever gets printed, not even a test page. The same happens on her Ubuntu system. I recently learned that a blinking power light means that the printer is complaining about something. What? http://h10032.www1.hp.com/ctg/Manual/c00905267#d0e5511enww "If an error message appears Read the error message that explains the problem and its solution." Huh? Where on a Deskjet D1420 could an error message possibly appear? Does it mean this message in /var/cups/error_log? E [13/May/2021:15:18:53 -0400] [CGI] Unable to create avahi client: Resource temporarily unavailable E [13/May/2021:15:18:53 -0400] [cups-deviced] PID 2094 (dnssd) stopped with status 1! Would the presence or absence of whatever avahi is cause the printer to complain? The printer used to print. The hardware connection has not changed in years.
