"DNF, Kernel not upgraded to /boot"

Good Day Fedora Community,

I'm a n00b in Fedora,

I was successfully login,
after Fedora 23 install,
using USB Live XFCE4.

After upgrade attempt to 24 succeed,
I realize that the kernel in /boot is still fc23.
No fc24 in /boot.

grub2-mkconfig change the grub2 title to (Twenty Four),
but the kernel is still fc23.

Thank you for any enlightenment.

I attempt to upgrade from 23 to 24 and succeed.

# dnf install dnf-plugin-system-upgrade

# dnf system-upgrade download -- releasever=24
# dnf system-upgrade reboot
# cat /etc/fedora-release
Fedora release 24 (Twenty Four)

"DNF system Upgrade Segmentation Fault"

Good Day Fedora Community,

I'm a n00b in Fedora,

I was successfully login,
after Fedora 23 install,
using USB Live XFCE4.

-- -- --

As a Fedora n00b, First I read the manual.

$ man dnf
$ su
# dnf install firefox

I turn out that I need a system-uprade plugin

# dnf install dnf-plugin-system-upgrade

# dnf system-upgrade download -- releasever=24
# dnf system-upgrade reboot
# cat /etc/fedora-release
Fedora release 24 (Twenty Four)

-- -- --

Doing the same thing from 24 to 25

# dnf system-upgrade download -- releasever=25
[SKIPPED] ...

Any DNF command, after system-upgrade command will result freeing read locks.


# dnf update

US Armed Services personnel: learn how to use OpenSC in Fedora to access trusted websites.

Short version: How can I set a default audio output device


Details: I have a media center pc running Fedora (25) hooked up to a receiver. The receiver doesn't do audio over HDMI so I have a separate optical audio cord for that. In the sound settings I can select the digital output and everything works properly, however when I turn the receiver off or switch inputs the computer sees that the optical audio has been disconnected so it reverts to hdmi (which doesn't work on my reciever.) The next time I go to use the computer it's switched audio outputs and I have to manually change it back to optical every time. Any way to force it to use digital out?

Just wanna say, I love Fedora, thanks to the Fedora team! I started using RedHat since 2003, then went onto Ubuntu a while, then switched back and never looked back again! haha
