Have a old quad core system that I've had since Fedora 10 I believe.
Recently, upgraded to Fedora 31, and it was still seeing all 4 cores.
Run BOINC, and recently notice that it was only showing 3 cpus
running? Machine is one of the 5 computers I have at house, but is
headless and access remotely via VNC. Other systems all show the right
number of cpus after updates, so not sure what might cause the issue.
The results of lshw-gui shows the 4 cores, but the dmesg shows only
CPU 0 - 2. Didn't notice this until the 5.7 kernel change, but not sure
exactly which update caused the change.
Any ideals what could fix this, or how to get specific reasons it might
have happened. Other machines are newer, some dual and one other
quad core. So, just this one??

Dnfdragora shows the above message when run from the CLI after it
has parsed all the available repositories. How do I identify whether it
is an issue with one of the repositories being used (without disabling
all repositories or moving them to another directory) or whether it is
an internal error?
I've got udev scripts that were working until I installed an update
today. Way down at the end of a chain of scripts udev starts, it sets
DISPLAY and runs a program (RepetierHost) when I plug in my
3d printer USB cable.
Did something change in udev to make it impossible to start
X11 programs now? It does run the script which invokes mono
to execute the .exe file, and that script produces zero
errors, I just don't have the program pop up on my screen
If I run the RepetierHost script from an xterm, it works fine and the
program starts up no problem.
This web page describes the scripts in detail:

Yup. Rookie error. I got mixed up between the .ovpn extension, and the
"openvpn" plugin name.
After successfully testing an OpenVPN link on a x86_64, I get the following
error on aarch64, as root:
# nmcli connection import type ovpn file <file>.ovpn
Error: failed to find VPN plugin for ovpn.
Both systems have openvn, NetworkManager-openvpn, and NetworkManager-openvpn-
gnome packages installed.
journalctl -f is completely silent, during this.
The only thing I can think of: the x86_64 server is headless, but has a user
session autologging into a desktop, on the console. The aarch64 VM is also
headless. In both cases I'm ssh-ing in. Maybe something gets started when
there's a desktop login, that's required for this. The only thing I see
running, on the x86_64 server is nm-applet, that surely can't be required.
The x86_64 server desktop login is not a root login, but I can ssh to the
x86_64 server, as root, and install the same ovpn connection without any
Should I install both extensions .ttf and .otf of the same font?
It is what I have now, but some applications (like xournal) offer me
twice the same font. Is it the reason?

for quite some time (weeks/months) ABRT does not seem to work anymore,
because fedora retrace servers are down:
Hochladen des uReport zum Server »https://retrace.fedoraproject.org/faf«
> mit curl: Could not resolve host: retrace.fedoraproject.org fehlgeschlagen
Effectively this means, fedora users are not able to report
application/system crashes anymore.
Is this a known issue?
What is taking soooo long to resolve it?
Thanks & best regards, Clemens
