gthumb crash on startup and bugzilla reporting
by Max Pyziur
Greetings,
I occasionally forget to shutdown gthumb before shutting down my pc.
On startup of the PC, I see a message indicating that gthumb crashed and
asking whether or not I want to report the bug.
(This is more of a nuisance; I can always start gthumb, and it works very
well.)
I click yes; the process runs, downloads debug packages, etc. When it is
ready to report, send in the information, I get the following message:
Backtrace is generated and saved, 145368 bytes
--- Running analyze_BodhiUpdates ---
Looking for similar problems in bugzilla
fatal: RPC failed at server. The API key you specified is invalid. Please
check that you typed it correctly.
abrt-action-find-bodhi-update [ERROR] Search for duplicate bugs failed:
None
('analyze_BodhiUpdates' exited with 2)
#######
So, I would like to complete this process; I have bugzilla credentials; do
I apply them somewhere in this report? Or do I have to acquire other
credentials for this API?
Thank you,
Max PYziur

Drivers for Realtec USB wifi adapters
by Robert McBroom
I have two Realtec USB wifi adapters an rtl8812au and rtl8822bu. For a
while I tracked driver updates on git with varying degrees of success.
Haven't seen anything since the 5.6 kernels. There was some note about a
generalized driver but I don't see anything in ../kernel/drivers or get
the devices enabled on boot.
Has anyone had any updates on these devices?

Enabling Apache HTTP/2 => Too many open files error
by Richard W.M. Jones
I fixed this now, but I could find virtually no documentation about it
online, so I'm writing this email to document what surely must be a
common problem ...
I wanted to enable HTTP/2 support in Apache on Fedora 38.
I followed the documentation here which worked [although it's way more
complicated than it needs to be, why isn't HTTP/2 the default out of
the box?]
https://httpd.apache.org/docs/2.4/howto/http2.html
Anyway the problem I had was that the server worked fine provided
there were not too many clients (and by "too many" I mean a simple
load test with 4-16 clients failed). Apache randomly threw 403
Forbidden errors, but with less load it gave a normal (2xx) response.
The first problem is the error is misleading:
[Wed Feb 22 13:24:52.013780 2023] [core:error] [pid 3047850:tid 3047899] (24)Too many open files: [remote 192.168.0.139:53738] AH00132: file permissions deny server access: /var/www/html/[filename]
If you concentrate on the second part "file permissions deny server
access" -- as I did -- then you'll be looking at file permissions,
SELinux, restorecon, ausearch etc. That's a red herring, there is no
permissions problem.
The real error is the first part "Too many open files".
It turns out that the default open file limit (1024!) is too low. To
change this and fix the problem:
# systemctl edit httpd
This creates an "override" file to which you should add (or you could
just create this file directly):
# cat /etc/systemd/system/httpd.service.d/override.conf
[Service]
LimitNOFILE=65536
and then restart Apache for the change to take effect.
Why on earth Apache needs > 1024 open files to serve a dozen clients
is not clear at all.
Rich.

Fedora (37) i686 32-bit virt-p2v ?
by Franta Hanzlik
Hi,
I want to virtualize any old i686 Windows XP 32-bit physical PC on F37.
Result from building virt-p2v boot disk:
# virt-p2v-make-disk -o /dev/sde --arch i686
virt-p2v-make-disk: cannot find /usr/lib64/virt-p2v/virt-p2v.i686.xz
You used the '--arch' option, so it’s likely that you will need to build
a virt-p2v.i686 binary yourself.
See p2v-building(1) section BUILDING i686 32 BIT VIRT-P2V for help.
It seems as virt-p2v.i686.xz blob isn't in Fedora (nor 'p2v-building'
man page, but it can be found easily).
What now? I see two possibilities:
1) it is somewhere on Fedora, but not in core repos
2) I have to build it myself - but have no idea about optimal way.
'p2v-building' man page recommends 32-bit chroot (without details),
or (on Fedora) use 'mock' - but it seems it is not there anymore.
Has anyone done this? What optimal way would you recommend?

recommended partition for swap with 0.5 TB memory
by Ranjan Maitra
Hi,
I am trying to install Fedora on to a new machine that has 0.5 TB RAM. Hard drives are 256 GB for / and friends, and 2 TB for /home partition. In the past, it used to be suggested that swap be twice that of RAM: this later changed to the same amount, and now it is very unclear (to me) because I have not tracked the latest recommendations. Anyway, what would you suggest? The machine is a Dell Precision 7920 with 28 cores/56 threads.
Many thanks for any suggestions, and best wishes,
Ranjan

How to create a Fedora 37 image for AWS
by Thomas Cameron
Hey, all! I work for AWS, and I put together a quick HOWTO on setting up
a Fedora 37 instance using KVM, and then converting it to a format that
can be used to create a new EC2 instance on AWS. Note that this is a
personal project, is not endorsed by AWS, and was not produced by AWS.
It’s just me.
https://camerontech.com/fedora-aws/
I am not a web guy, I just did a super basic HTML page using Seahorse.
It’s literally something I threw together, and I am sure I missed some
things, but I hope that it is helpful for anyone who wants to build
their own image. I know there are a bunch of images already out there in
the community, but I wanted to document how to do it for yourself.
I hope you find it helpful!

Taking better advantage of BTRFS
by John Mellor
Ok, I'm anticipating a firestorm of BS responses on this, but here goes
anyway.
We've now had BTRFS as the default filesystem for some time in Fedora.
However, there has been almost nothing done to take advantage of its
capabilities. This leads to some obvious questions about future work:
1) When are we going to see removal of the EXT2 /boot partition? It is
no longer required, as the boot process has been able to use BTRFS for
years now.
2) When are we going to see timeshifting tools built into the desktop,
ala Solaris? That's incredibly useful for developers.
3) The existing Windows-like update mechanism is undesirable. It solves
a non-existent problem on filesystems with inodes. Like all Unix-like
systems, even Ubuntu does not require this. The ability to snapshot
means that the weird reasoning that requires 2 reboots to install
virtually all update packages is no longer required under any
circumstances. When is the software update mechanism getting a
fundamental redesign?
4) When is a standard backup mechanism that takes advantage of
snapshotting going to be in the distro? The published backup packages
do not seem to be aware of the better capabilities available in BTRFS.
Wrapping a few CLI tools in a GUI seems like it should be obvious, maybe
200 lines of shellscript or less.
5) If you encrypt your filesystems, the BTRFS built-in encryption
mechanism is not used. Why not? LUKS is still in use, even though that
is more complicated and slower. I note the possible ability to encrypt
being added if F38, but it seems like baby steps when a general solution
is already in the code.
6) Compression is not the default. Why not? SSDs are 10x slower and
disks are 100x slower than the processors of even 10 years ago, so this
omission is slowing the system down.
7) Keep the last 3 update snapshots, not just the last 3 kernels. This
would keep backout scenarios a lot more consistent and functional.
If I look at the changes coming in Fedora 38, I am disappointed in the
lack of innovation. All of these items should be in there to make the
system cleaner, better and faster. Most of these asks have already been
in SUSE for many years now, and are well debugged and understood.
Fedora is supposed to be leading the way at the edge, not way behind
it. Or am I missing something about the politics of the distro?

Unable to login after fedora re-install
by Geoffrey Leach
After moving from F37 to F36 and re-installing a user directory (with dot
files) I discover that login for that user fails. No messages in /var/log,
no error message.
I assume that the problem is somewhere in one of the dot files. Any
suggestions?
Thanks.
