Whenever Discover, the KDE App manager starts, it shows this message:
Please make sure that Appstream is properly set up on your system.
Wikipedia tells me that:
AppStream is an agreement between major Linux vendors (i.e. Red Hat,
Canonical, SUSE, Debian, Mandriva, etc.) to create an infrastructure
for application installers on Linux and sharing of metadata.
but there's little more on the web.
Discover seems to run just fine.
How can I verify that Appstream is set up properly? If not, how can
the installation be fixed?
Thanks - jon
Thursday evening we had a power failure and I shutdown all the computers
to get the load off my UPS's. I have booted the Fedora 28 computer this
morning and a what was a non-problem has blossomed into a real one. The
other three all booted normally when I started things after the power
came back on, however I did not try the F28 until this morning.
Since the F28 install a window has always come after the xfce desktop opens:
"Oops, We're sorry, it looks like boot_image-/
vmlinuz-18.104.22.168.fc28.x86_64 crashed. Please contact the developer ..."
I ignored it until now since it seemed to be meaningless, the system
connected to the LAN and the internet and went happily on its way. Not
so today, the cursor arrow sits in the error message box and can't be
moved and the Only thing that works is ctrl-alt-F1 which brings back the
user boot screen asking for a password, normally bobg, but I tried
alternate as well as root, which brings up Gnome, also frozen in some
strange fashion, I never use that so did not investigate much there, a
presentation hard for me t read. Along with the Oops window is another
that ells me I am connected to enp2so or whatever.
Tried the two alternative kernels, no difference.
I can ssh from this computer which allows me to reboot it conveniently
[bobg@Box10 ~]$ ssh -X bobg(a)192.168.1.83

[bobg@box83 ~]$ su
[root@box83 bobg]# reboot
I tried "startxfce4" via ssh from this computer after a fresh start, the
xfce splash screen comes up but that crashes with a lot of errors and
I'm not even certain that approach should work.
So I am stuck and need some help troubleshooting.

Just recently my KDE update widget starting showing that I have 2433
updates available. When I look at the versions of the available updates,
it shows me the same versions that are currently installed on my system.
Also, running "dnf upgrade" is only showing several updates and not the
What would cause this? I'm assuming that the cache that the widget uses is
somehow empty or corrupt. Is there a way to correct this? I'm a little
hesitant on just letting the widget install or try to install the 2433
My system is up to date running Plasma version 5.13.4 and KDE Frameworks
Thanks for any help provided.
Using dd to back up a DVD (for in case dvd gets damaged), I am getting
frequent messages like
..... File shrank by 1069672448 bytes; padding with zeros
So, the .VOB file copied to HD is all messed up????
I do not know yet, because the process is still in progress.
In the past, I never had this issue, and I have seen many
of my dvd's and CD's get damaged when inserted into friend's
home entertainment centers, and had to rebuild them from HD backup.
Any clues how to prevent this message coming from dd ?
I want to enlarge the fonts I am using in terminal (when logging as
non root) on Fedora 28.
I installed the terminus-fonts rpm on fedora 28 (dnf install terminus-fonts)
When I try from a terminal (I mean not gnome-terminal, but the
terminal you get into when logging in
without GUI/X windows)
"cannot open font file"
cp /usr/share/fonts/terminus/ter-132b.pcf.gz /lib/kbd/consolefonts/
and running again the same setfont command, still it fails.
I am usign GNOME, not KDE (not sure it matters in this case).
Any ideas ?
After my trusty ThinkPad W700 failed I've been forced to fall back to an
ancient Dell E6500 laptop with Broadcom BCM4322 WiFi. Apparently Fedora 28
Workstation doesn't support that chipset. I'm forced to drag around a
<long> Ethernet cable. No matter what I try, I cannot enable WiFi.

For some unknown reason, an HP laserjet I had been using for some years
suddenly stopped working with F28. After some investigation, I found the
Sep 14 14:32:20 nbecker2 cupsd: [Job 1202] PID 14791 (gs) stopped with
After more searching on the web, I found the answer was
lpadmin -p m750 -o pdftops-renderer-default=pdftops
apparently tells cups to use cairo instead of gs and this fixed my issue.
I wonder, I cannot boot Fedora without - amd_iommu=off - that's the
first issue. You guys?
I'm on Lenovo Ideapad E485 with AMD Ryzen 5 2500U & F28.
Second issue is - I use external monitor (via HDMI in "join" setup) and
if system went to sleep or HDMI got disconnect then laptop's display
would show something that I do not think many of you might have seen,
unless you are middle-aged at least - it's noise of that kind like in
old days tube TVs would show when signal was lost.
It looks very funny but also so very wrong :)
But when displays both are okey, and when I lock gnome(@Wayland) session
and unlock/login again then both screens would be ... kind of blinking,
infrequently. Reboot is needed to get rid of blinking.
I've tried kernels up to 4.18.5-200.fc28.x86_64
Care to share your thoughts?
many thanks, L.
