Server entering Emergency Shell, but continues fine after pressing Enter
by Quinn Comendant 13 Sep '20

13 Sep '20

Hello all, I've got an odd problem that doesn't seem to be mentioned anywhere. I have several identical CentOS 7 servers (GCE instances). I recently ran `yum update` and rebooted all of them. All the servers came back fine except one. I opened a connection to the serial console of the broken server, and was greeted with this prompt: … Cannot open access to console, the root account is locked. See sulogin(8) man page for more details. Press Enter to continue. I pressed Enter, and the boot process continued successfully! Just to test, I restarted the server again, and the same thing happened: I had to manually log in to the console and press Enter before it would complete the boot process. No other step was required. I also tried creating a snapshot of the disk, and booted a new VM with a boot disk imaged from the snapshot. The same problem occurred, pressing Enter was all that was required. Earlier in the boot log, it shows "Started Emergency Shell", which is why there was a "Press Enter" prompt. The error that the "root account is locked" isn't the issue; the root account is locked on all our servers. So, in summary: something is causing the server to enter an Emergency Shell, but continues successfully after pressing Enter. That's odd because if Emergency Shell is loaded, usually something more serious is happening and requires more actions to get the server to boot. Anybody have any idea what could be causing this? I don't see any significant errors in the boot log, but I would appreciate if anyone has a moment to help me look for issues. Here's a copy of the serial console boot log – you can find the "Press Enter to continue" on line 536: https://write.as/dwuts24dcw6yh0kf.txt Thanks! Quinn

Thunderbird won't start after move to new box
by Gary Stainburn 12 Sep '20

12 Sep '20

I've tried moving my Thunderbird profile from one C7 box, a standard PC to another C7 box, a DELL server. I did this by rsync'ing ~/.thunderbird. However, on the new box, Thunderbird only starts if I run it -safe-mode. If I don't run it in safe mode I see the window flash up and instantly close. No errors or notifications appear in the terminal window., Anyone got suggestions on what could be wrong, or how I can diagnose it? Google just seems to bring up hits for problems on Windows boxes.

Plasma problem with numeric keypad
by Alessandro Baggi 08 Sep '20

08 Sep '20

Hi list, I'm running CentOS 8.2 with Plasma from EPEL and I noticed that I have problem using numeric keypad of my keyboard when using plasma application like Konsole, Kcalc, Konqueror and all application of Plasma. Using Firefox, Thunderbird, xterm, Libreoffice all works as expected. So this problem is related to Plasma application. I noticed the same problem on sddm login. I noticed that to make the numeric keypad to work I need to press SHIFT+NUMKEY. I tried to manage Plasma keyboard configuration but nothing worked. I tried my keyboard on other PC and distro but the problem does not occour. I should try this using GNOME or XFCE but being a KDE user I would avoid to install the others. There is a way to solve this problem? Thank you in advance. Alessandro.

Conversion from Centos 5 to Centos 7 & mailx changes
by Gregory P. Ennis 07 Sep '20

07 Sep '20

Everyone, I have just upgraded a Centos 5 server to a Centos 7 server and am having difficulty with a change of behavior of mailx with the use of a command line of : mail -s 'This is the subject' user(a)domain.com < text_file.txt On Centos 5 when mailx was used by a program started by a cron job we were able to send a text file as an email message and the headers did not contain 'Content-Transfer-Encoding: base64' On Centos 7 the headers contain 'Content-Transfer-Encoding: base64' and when the client gets the e-mail they are unable to open it up. The interesting thing is that on Centos 7 when the command line is used by typing the above command 'Content-Transfer-Encoding: 7bit' is placed in the header and the client can see the e-mail without a problem. I have looked for a way to control the 'Content-Transfer-Encoding:' header to '7bit' when we use a cron job, but I have not been able to figure out how. Your suggestions would be appreciated. Thank you, -- Greg Ennis

ansible: which repo?
by Leon Fauster 06 Sep '20

06 Sep '20

What would you recommend: ansible is in EPEL8 and ConfigSIG. For the latter I do not see any sources in git.centos.org. Where they come from? I wonder with which repository I should use (long term)? dnf not checking gpg signature sounds scary: https://github.com/ansible/ansible/blob/v2.9.13/changelogs/CHANGELOG-v2.9.r… -- Leon

Updating ca-certificates
by isdtor 03 Sep '20

03 Sep '20

This is probably a stupid question: what is the correct way to update certificates if one has installed additional certs with update-ca-trust and the distro releases a new version of ca-certificates?

Tracking or checking backported kernel patches from upstream
by Carlos A. Carnero Delgado 03 Sep '20

03 Sep '20

Hi! I'm interested in finding out if a couple of upstream kernel patches were backported into CentOS (RHEL), in particular this one <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…> and this one <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…> . What's the procedure? After reading an article <https://www.redhat.com/en/blog/what-backporting-and-how-does-it-apply-rhel-…>, I went into Red Hat's bugzilla, and tried several search terms (including the kernel's commit ID) but found nothing. Thanks!
