F32, mDNS, and nsswitch.conf
by Kevin Becker
I've been using Fedora on my laptop for a few years now, and on a newly
built desktop for since just last summer. I've never had an issue
upgrading, but I only recently became aware of the recommended post-
install steps.
https://docs.fedoraproject.org/en-US/quick-docs/dnf-system-upgrade/
So this time, after upgrading to Fedora 32 I followed the guide. When
I was looking through the results of rpmconf -a, I chose to install the
newer config files as I hadn't made any local changes, except in
sshd_config.
After the upgrade, it turned out I could no longer print from my
desktop. My printer was discovered via mDNS and configured
automatically in the past, it was really nice actually. I tried on my
laptop as well and had the same result. I basically ignored it for a
few days, installing updates and seeing if it was fixed, but it never
was. Monday I had a bunch of printing to do for my kid's "remote
learning" school assignments so I figured I'd dig into it. It turns out
mdns4_minimal had been removed from host resolution in nsswitch.conf.
I restored the nsswitch.conf.bak on both machines and my printer is
back in business.
I'm not sure if this is a bug? Was it removed for a reason or should I
report it? Maybe it has been gone for a while now, and I've just been
bringing the config forward. I suspect whatever package adds mDNS
functionality also adds the entry to the default config and then I
resotred the default back so this is basically user error.

F32 Install hangs on Lenovo x140e
by Robert Moskowitz
I downloaded the F32 Server netinstall CD.
I wanted a F32 Workstation netinstall, but I could not find one. :(
The system is a Lenovo x140e that I got used on ebay with no HD and only
4GB memory. I pulled an SSD that had F28 on it and added 4GB memory.
this system will not boot as is.
I put the CD in a USB DVD/CD device, turn on the computer, press F12 for
boot menu and select the CD.
I get the Install 32 or check media option and select Install.
After a bit of time it goes back to the system boot message offering to
start F28 (which won't work anyway).
What do I do to figure out what is wrong?
I pulled an old Lenovo x120e and did the same start up. I got into the
install menu for F32, so I don't think it is the CD media.
any one have experience with the x140e? Anyone can give me some
suggestions?

SELinux is preventing mktemp from using the dac_read_search
capability.
by Robert Moskowitz
I had this on F30 and pretty much ignored it. Now I am getting it on
this new F32 install:
What daily process is causing this?
SELinux is preventing mktemp from using the dac_read_search capability.
***** Plugin dac_override (91.4 confidence) suggests **********************
If you want to help identify if domain needs this access or you have a
file with the wrong permissions on your system
Then turn on full auditing to get path information about the offending
file and generate the error again.
Do
Turn on full auditing
# auditctl -w /etc/shadow -p w
Try to recreate AVC. Then execute
# ausearch -m avc -ts recent
If you see PATH record check ownership/permissions on file, and fix it,
otherwise report as a bugzilla.
***** Plugin catchall (9.59 confidence) suggests **************************
If you believe that mktemp should have the dac_read_search capability by
default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'mktemp' --raw | audit2allow -M my-mktemp
# semodule -X 300 -i my-mktemp.pp

Extensions Panel on Gnome Menu Doesn't Do Anything
by Tim Evans
The drop-down gnome shell menu in F32 (upper right hand corner of the
desktop) has a new "Extensions" panel now. It's very prominent, with an
extra large @-like icon.
Unfortunately, it does nothing other than change from black to blue when
clicked. Is it supposed to do something else?

Dual monitors not always powering off
by Dave Ulrick
Hi,
I have dual monitors configured on a Fedora 30 PC. I'm using the XFCE4
desktop. Using xscreensaver I've configured the monitors to be powered
off after 15 minutes of inactivity. 90+% of the time the monitors do get
powered off, but every once in a while I'll come back to my PC and see
that the monitors are blanked with backlight on instead of being powered
off. Any suggestions on how I might troubleshoot this?
Thanks,
Dave

Creating a livecd for 32 on 30
by Geoffrey Leach
Goal: to create an install live CD on Fedora 30 for v32.
When I did this a year ago for 28->30, this went without a hitch. This
time, not so.
I'm following "Creating and using live CD" from the official docs.
Packages livecd-tools and spin-kickstarts are installed.
This is an xfce install, so I'm using the fedora-live-xfce.ks
selinux is not onstalled.
So --
I can't find the kickstart configurator. If I recall correctly, it was
on 28.
livecd-creator appears to want to be run from the kickstart directory,
as --config=/usr/share/spin-kickstarts/fedora-live-xfce.ks can't find
subsequent (included) files.
livecd-creator goes to the fedora repositories and then wants 1489
rpms. Presumably these are for v32, but that many?
I'd appreciate some advice. Thanks.

Unable to boot from imported OVA file in virt-manager
by Sreyan Chakravarty
Anyone here familiar with virt-manager ?
I have an OVA file of Windows 10 from VirtualBox that I would like to
use in virt-manager.
I have imported the file, but when I try to boot it shows "No bootable
device", "Hard disk is not bootable".
I tried changing the I/O type to "virtio" and the disk type to qcow2,
but no dice.
What am I doing wrong ?
Is there any way I can convert the OVA to VMDK in Fedora ?
Thanks.

Opera Mail & Browser after upgrading Fedora31 to Fedora32 . Ed
Greshko.
by Ger van Dijck
Hi all , Hi Ed ,
I did some thinking and studying : A long time ago I found somewhere
opera-stable-54.0.2952.71-1.fc29R.x86_64.rpm but I don't know and have
fotgotten where .
I installed it and in the version fc29, -fc30, and -fc31 it runs fine. In
the version fc32 the application won't launch : So I reinstalled it and
got the message already installed.
I can imagine that this old rpm (fc29) is outdated ,so the question is
where can I find the newest version (opera-stable-68.0.3618.63-0 ((fc32R))
.x86_64.rpm if it exists and install it and then try to launch this newest
application onder fc32 ?
Second problem : Also a long time ago , don't ask me when or where I found
opera-12.16-1860.x86_64.rpm and installed it. Purpose was and is the
possibility to use opera mail wich long ago was under fedora to use and
since the browser was separated opera mail is not running under fedora .
In the versions fc28 , -fc29 , -fc-30 and -fc31 no problems runs fine . In
the version fc32 it is gone . So I tried the reinstall it and got the
following messages
Libgstreamer-0.10.so.0
Libgstbase-0.10.so.0
Libgstvideo-0.10.so.0
are missing.
How going on ?
Kind regards ,
Ger van Dijck.

Failure to boot after update to Fedora 32
by Andrew Wood
Hello,
I had Fedora 31 installed on my laptop and I decided to update it to
Fedora 32.
After the reboot then Fedora stops and brings up a terminal session.
I'm invited to inspect the system log with 'journalctrl'.
Looking through the log then I have:
May 04 17:03:09 localhost systemd[1]: Started dracut pre-mount hook.

Any suggestions of how I might fix this? One thing which I don't
understand is the device here. Is it systemd[1]??
Thanks for your help and assistance,
