This will refresh the repodata with version 26 and then install/upgrade 1000+ RPMS to proceed.  Once it’s done, reboot and pray your system comes back up.  But if you’re like me and running Nvidia graphics card than when you reboot your system will probably hang after the grub menu.  It is advisable that you go grab the latest Nvidia driver ahead of time, unless of course, you like running out of run-level 3 or single user mode.

Here’s a good guide to follow on updating the Nvidia drivers for your new kernel.   https://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/

On this note, I usually exclude any new kernels from downloading when updating just to avoid the nvidia mess.  To exclude using dnf.

Add to /etc/dnf/dnf.conf under [main] section:

 

$ sudo echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6

But if you want it perm set

$ sudo vi /etc/sysctl.conf

append…

net.ipv6.conf.all.disable_ipv6 = 1

Seems even after doing this on my Fedora box, that didn’t work either…it was still sending DNS aaaa traffic out.   Added this and rebooted..and this seems like it fixed it

$ sudo touch /etc/modprobe.d/disable-ipv6

$ sudo echo “options ipv6 disable=1” >> /etc/modprobe.d/disable-ipv6

Another possible way,

$ sudo vi /etc/default/grub

GRUB_CMDLINE_LINUX=”ipv6.disable=1 rd.lvm.lv=fedora/swap rd.md=0…..

$ sudo reload

$ sudo grub2-mkconfig-o /boot/grub2/grub.cfg

$ sudo reboot

And even yet another possible way…

$ sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
$ sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
