I've got an odd problem that I was hoping for some help on.
The laptop was previously working fine, I am running F30, updated regularly.
I've got an Acer laptop that has been shutting down suddenly. (I
suspect a bad battery, working on that.)
After a sudden shutdown last night, I now get a kernel panic on boot
right after "Starting Switch Root..."
I was able to boot from a USB stick, and was able to read the journal,
but I didn't see anything obvious to help.
I was able to get all of my data off of the (encrypted) disks, so
that's not a problem, but I don't want to just give up, and wash and
reload too quickly.
With the SystemRescueCd I backed up the /dev/sda6 partition in /mnt/backup/ naming "diskimage"
After backing up operation the file has the automatic extension like "diskimage.000".
Is this file ok to restore?
If I name it "diskimage.gz" then it is automatically renamed with this extension "diskimage.gz.000"
But here below
the file is name like this:
Do I have to name with the .pimg extension during backup to restore correctly?
And how can I restore it?
I upgraded to F31 late last week and I am missing the MiscFixed 16 font that I prefer using. Where would I find it?

I am developing a Qt app in Fedora 31 using the default GNOME wayland session and I am very sorry to see the state of Qt in this configuration.
1) qt creator crashes often (https://bugzilla.redhat.com/show_bug.cgi?id=1773356) the crash report tool does not seem to help
2) drag & drop does not work in Qt creator (and in no other Qt app) (https://bugzilla.redhat.com/show_bug.cgi?id=1774762 and https://bugreports.qt.io/browse/QTBUG-80303)
3) main window geometry cannot be restored when the application restarts (https://bugreports.qt.io/browse/QTBUG-80612)
I think GNOME / Wayland / Qt it is just not ready and should not be offered as the default desktop session for Fedora.
If I force Qt to use X11 emulations, things are much better.
Probably Qt is responsible (but in the bug reports someone says that KDE / Wayland works well), and GNOME is not Qt, but there are so many Qt apps, that sending new users to a non working environment re-enforces the fact that "just works" is not true in Linux.
Last week, I was to participate in a "Zoom" meeting for a charity that
I'm involved in. I have the needed software on my rarely-used windows-7
box. But I could not complete the windows-7 login (some problem with a
windows-7 service). I've since found there is a "Zoom" client for
Fedora. "dnfdragora" does not find anything for it. But I found a web
page that I hope has what I need. I've downloaded the package
("zoom_x86_64.rpm"), and I've downloaded a "Public Key"
("package-signing-key.pub"). The web site from which I've downloaded
these also has a line:
Key fingerprint: [some 40 hex digit number]
1. Do the 2 files need to be in a specific place to do the install? If
2. Do I need to be "root" to do the install?
3. What do I do with the "Key fingerprint"?
4. How do I do the install (preferably using "dnf")?
In this extended period of Covid-19 isolation, is there a
videoconference package available?
Hosted systems like Zoom are not opensource, do not use a browser as a
client, feed connection data to Facebook, only allow 2 participants for
free, and not available for a local install.
I thought of Webex, but its Cisco. Maybe its just me :-)
I took a quick look at Jitsi, but users say it has a fatal extreme
processor utilization bug, the rpm packages are 3 years out-of-date, and
does not seem to be present in the normal rpm repos.
I also took a quick look at BigBlueButtion, which looks pretty good.
However, it only runs on an ancient version of Ubuntu, and uses a shell
installer for some unknown reason.
This seems like a major application type that appears to be completely
missing from the repos. Is anyone building one, and just hasn't
announced it yet?
I've managed to use the kickstart files to create a Fedora 31 KDE live CD
without any problems.
Actually I have a simple python script which conglomerates all the KS
files together to make it easier to deal with. Then I customize it and
have it copy some files into the /var/www/html directory.
I am now trying to see what is necessary to have it encrypted (with Luks)
so it prompts for the password at boot time.
part /boot --size=512 --fstype=ext4
part / --encrypted --cipher=aes-xts-plain64 --size=8200 --fstype=ext4
Those commands don't seem to make it encrypted.. Is encryption ignored for
the livecd? Am I not doing something correctly, or is this not possible?
I have just installed the latest version of Fedora Gnome on my HP laptop. I
had to import a 50 GB OVA file from my USB HDD to my hard drive via USB 3.0.
When the copying was taking place through VirtualBox, the system hung
almost completely, I was not able to even move my mouse.
Why does this happen ?
It seems to be the case for Debian based OSes, but then why is it happening
in Fedora ?
I just formatted from Windows 10, and while I hate a lot of things about
it, it never made the system unusable during heavy I/O operations. I had
multiple tabs in Chrome open without any lag whatsoever.
I say this, not to criticize Fedora but to point out this should be the
case in modern OSes. So why am I facing this issue?
Let me know what you think and if any further information is needed.
