1st problem when installing f38
by François Patte
Bonjour,
I am following advices given in answering my previous post "issue...."
and I get f38 installer.
The installer complains that there is a duplicate UUID on some disks :
parts sde1 and sdf1
That's true! Running blkid gives:
/dev/sde1: UUID="4a28174a-f38b-4938-233f-85f76ce585a8"
UUID_SUB="88a5f939-72d4-b330-95e6-52fa0b826203" LABEL="dipankar:4"
TYPE="linux_raid_member" PARTUUID="c257bd85-01"
^^^^^^^^^^^
/dev/sdf1: UUID="4a28174a-f38b-4938-233f-85f76ce585a8"
UUID_SUB="99b46805-aa31-1711-21dc-89cb7177d025" LABEL="dipankar:4"
TYPE="linux_raid_member" PARTUUID="c257bd85-01"
^^^^^^^^^^^^
But it is not the only case and it does not complain for the other one:
/dev/sde2: UUID="5240f249-7feb-6832-6682-805f97c4abea"
UUID_SUB="0e21ab45-27a2-f588-48a9-cd46d0dc6237" LABEL="dipankar:5"
TYPE="linux_raid_member" PARTUUID="c257bd85-02"
^^^^^^^^^^^
/dev/sdf2: UUID="5240f249-7feb-6832-6682-805f97c4abea"
UUID_SUB="5838df23-817e-f3cb-19f3-31da8d3e99d0" LABEL="dipankar:5"
TYPE="linux_raid_member" PARTUUID="c257bd85-02"
^^^^^^^^^^^^
What does this mean? And what shall I do?
The installer suggests to unplug these disks (or at list one of these
disks) but, as you can see these disks are members of a raid array with
the swap, /var and a crypted partition (sde1 and sdf1) and /home (sde2
and sdf2)....
Is it possible to unplug one of the disks (say sdf) and make an install
with a raid1 in degraded mode (+lvm) then, when the install is finished,
to plug again the disk sdf and synchronise the partitions with mdadm?
Moreover, I don't understand why the problem occurs only with sde1 and
sdf1 and not with the other disks (sde2, sdf2 as already pointed) : I
have 6 disks, and more partitions, paired in pairs as raid members.
Thank you for lights.

Desktop scaling on 3 different Thinkpad X1
by Frederic Muller
Hi!
At each new Fedora release I have 3 thinkpads to 'upgrade'. In fact I do
fresh installs for those and have a list of steps to perfom so I don't
forget anything (list which I maintain and update at each release as
things do change over time).
Desktop scaling is always tricky and this time I only get it to work on
1 of those 3 Thinkpads. They are 3rd, 6th and 8th generation ones.
Currently it only works on the 8th gen one.
I type this:
gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"
On 3rd gen I can only do 100% and 200% and on 6th gen I cannot even do
200% as it says there is some HW limitation message preventing to change
anything.
Any advice on how to troubleshoot the issue would be very welcome.
Thank you very much.

OT: Working on script to add Memtest86+ version 6.20 to Fedora boot menu
by Michael D. Setzer II
The latest broken setup is for
149856 Jul 22 2022 /boot/memtest86+-5.31
There is a bugzilla working on adding 6.x but has been a
work in progress for some time.
The 5.31 only installs for non-UEFI and doesn't actually
work. (At least for me) memtest-setup doesn't run on
UEFI setups..
I've found that the 6.0, 6.10, and now 6.20 versions do
work with Fedora 36 and Fedora 37 if manually setup..
Does not work if Secure Boot is turned on, since files
don't the the Micro$oft blessed signatures.
My script works for my machines, but have just basic
setups. Don't know if code could be added check for
situations were it wouldn't work.
Script gets the latest version of memtest files from site,
and copies them to /boot directory and creates a
/etc/grub.d/20_memtest86+ file that would require
grub2-mkconfig to be run to create the boot menu
option.
This is my 6th version of script. Perhaps someone with
more knowledge would have suggestions to make it
better or say if it is just better to wait for an official
update? I just like having memtest available.
My script getmemtest6.sh
#!/usr/bin/bash
clear
mkdir /tmp/memtest
cd /tmp/memtest
rm index.html -f
wget https://memtest.org/
f=$(grep -m1 binaries.zip <index.html | cut -f2 -d\")
rm index.html -f
wget -nc https://memtest.org/$f
echo $f
zip=$(echo $f | cut -f4 -d/)
unzip -u $zip
boot=$(find / -maxdepth 2 -iname loader | sed 's_/loader__')
echo $boot
cp memtest64.* $boot -p -v
ver=$(echo $zip | cut -b10-13);
{
printf "# \x21/bin/sh\nexec tail -n +3 \$0\n# This file provides an easy way to add custom
menu entries. Simply type the\n";
printf "# menu entries you want to add after this comment. Be careful not to change\n#
the 'exec tail' line above.\n" ;
printf "menuentry 'Memtest Legacy' {\n echo 'Loading memtest $ver for BIOS BOOT
SYSTEM'\n linux /memtest64.bin\n}" ;
printf "\nmenuentry 'Memtest UEFI' {\n echo 'Loading memtest $ver for UEFI BOOT
SYSTEM'\n linux /memtest64.efi\n}\n"; } >/etc/grub.d/20_memtest86+
chmod 755 /etc/grub.d/20_memtest86+
Script creates /tmp/memtest to handle files.
uses wget to get the latest index.htm file from site.
finds the latest line with binaries.zip
Then downloads that file and unzips it.
Was talk of different possible boot directory locations??
So have an option to locate it?? Might just be better to
hard code /boot?
Have it copy the two memtest64 files to /boot.
144344 May 7 17:06 /boot/memtest64.bin
145408 May 7 17:06 /boot/memtest64.efi
There are 32 bit versions also.
Pull the version from file, and then manually create
/etc/grub.d/20_memtest86+ very basic file.
In my G4L project that uses grub4dos, had to use
memtest64.bin if booting from regular grub4dos and
memtest64.efi if booting from grub4dos-efi.
Otherwise gets errors with other file.
grub2 seems to handle either version of file?
But make the 20_memtest86+ to have option for both?
Script doesn't run the grub2-mkconfig file like the old
Fedora process with memtest-setup would then just say
it needs to be run.
Perhaps memtest isn't important to many. Once had a
new $8000 HP server that had weird issues, and
memtest found a problem that only happened at test8.
Vendor then replace ram. Recently had a machine that
had worked fine for many years with 4 4G sticks. But
was having random issues. memtest failed with all 4
modules. After testing. Found that all 4 memmory sticks
passed all test if run individual. Turned out the 3rd slot
has something wrong. So machine passes all these with
slots 0,1, and 3 populated.
Thanks for any suggestions..

Thunderbird quirk
by Robert McBroom
The flame icon on a message in the Inbox used to send the message
immediately to "Bulk Mail". It has stopped doing that. Messages that the
email provider flags do go to the "Bulk Mail". Now the message has to be
manually trashed. It was very nice to just flag messages and have them
go away.
Is there a setting I've missed that has changed?

Boot failure with 6.3.4-101.fc37
by John Pilkington
After dnf upgrade today, abrtd.service failed to start, with dependency
failures for abrt: ccoredumpctl, kernelpanic detection and kernel log
watcher.
Booting the previous kernel also hung for 10s of seconds but seems ok.
6.2.15-200.fc37
systemctl reboot hangs for 5 minutes with akmods, presumably from
rpmfusion for nvidia, before entering the reboot.

gimmicks for most & a question networking curious/experts - ? MACSEC
by lejeczek
Hi guys.
Looking at macsec I've only started - so go easy on me with
my possibly trivial questions - and write here in hope,
that some of you have expertise to tell...
To start with the most basic of what I ponder over - basic
in my mind though I get, that it does not have to be that or
simple/obvious - is MACSEC with 'bond' as parent or in other
words: macsec "on" a 'bond' network interface.
Should such a "thing" work, does it work?
All & any thoughts shared are much appreciated.
many thanks, L.

Virtualbox not working on kernel 6.3
by ogio.spam
Hi all,
there is a documented issue for Virtualbox and new kernels (6.3).
All VMs stuck on starting.
It seems to be a problem related with IBT (enable by default on new
Fedora kernels) that causes the VM to refuse to load.
One reference here: https://www.virtualbox.org/ticket/21435
I'll try to disable IBT at boot and try to use VM's but the question
is:
There is already a solution (IBT is there why?) or there is only this
workaround?

OT question about let's encrypt
by Tim
Hi,
After discussing let's encrypt on here the other week, I was wondering
if you get the same nonsense warnings as my hosting service provider
was emailing me over and over:
---- begin paste ----
⛔ example.com (checked on May 30, 2023 at 12:25:12 PM UTC)
There is no recorded error on the system for “www.example.com”. This
might mean that this domain failed DCV (Domain Control Validation) when
the system requested the new certificate, but the domain has since
passed DCV.
---- end paste ----
And a whole pile more identical ones for each sub-domain.
Essentially it's an "error, no error" message. i.e. Something *may*
have gone wrong before, or may not. But nothing is wrong, now.
Utterly pointless, nothing I can do about it (one of those cpanel
controlled turnkey webservices run by people who don't have to know
what they're doing), no useful information for me to do something about
it, and by the time you've seen it crying "wolf!" umpteen times you
ignore it and won't notice an actual error message, later on.

issue with dnf system upgrade
by François Patte
Bonjour,
Today I tried to upgrade from fc34 to fc36.
Downloading the package was okay. Problems occur when I agreed to
system-upgrade-reboot:
1- No display... I could only dee the led showing HDD accesses
2- After sometimes (when no more accesses were showed, I press enter key
on the keyboard and the system rebooted on fc34 kernel and still no
display...
3- I pressed the "y" key on the the keyboard (in case the system upgrade
was asking some question...) and the display came (hurray!) : I could
see the login screen of the fc36 version. I could login but all my
previous display settings were gone....
4- I checked the kernel with command uname -r and it is stille the fc34
kernel which running... No f36 packages have been installed in /boot....
5- many packages from fc34 remain installed and only some fc36 packages
have been installed.
What can I do to have a coherent fc36 install now?

Re: Cable modem packet loss?
by J.Witvliet＠mindef.nl
From: "Alex" <mysqlstudent(a)gmail.com<mailto:mysqlstudent@gmail.com>>

To: "Community support for Fedora users" <users(a)lists.fedoraproject.org<mailto:users@lists.fedoraproject.org>>
Subject: Cable modem packet loss?
Hi,
I have an E3-1240 fedora37 postfix system using SSDs connected to a cable modem that's having problems with dropped packets. There is one other fedora37 server (E5-1650) directly connected to the cable modem that is not having the same problem, although it's just routing packets, not really doing much processing of data. The server with the problem is using libreswan to create a VPN between itself and an i7-7700K with fedora37 managed at OVH, thinking it would be more resilient than the cable connection itself. The problem also happens without the VPN, but perhaps not to the same degree.
I think the server is certainly powerful enough to process the amount of DNS queries, but there's also a lot of timeouts.
How do I troubleshoot this? It's the bridge experiencing the dropped packets, not the interface itself, it seems?
They're not packet errors - just dropped packets. Perhaps the processor can't handle the traffic?
Do you have a server connected to a cable modem? Is there something about it being a cable connection that could be causing this?
There's about 27k dropped packets in about 12 hours of uptime.

Perhaps it’s not relevant in your case,
But many of my colleagues have also problems with their cable modem.
While turning it on, it claims it can handle an MTU of 1500 bytes, while in reality all above 1472 causes vague problems.
This should have been handled through auto-probing of ICMP-protocol, but it isn’t.
But your might be a different issue….
