Thank you! The Disable Ipv6 from sysctl finally allowed me to disable IPV6!

Thanks! Fixed my network issue. All of a sudden, Mint 18 had network issue. Most sites in Firefox would not work. When I checked, the IP was an IPV6 address, not the IPV4 I expected. Added your lines and all is good.

Mint 18 doesn’t have gedit. The default editor is Xed. Yes, I’m a noob and I had to use Google to figure it out.

Thanks for the explanation! Even 4 years latter it still helps.

Also for disabling it from linux kernel.
Find if its installed, lsmod list the modules:

lsmod

Remove it with rmmode:

rmmod ipv6

Thank you. I’m a super noob and this is the first thing I read and applied as far as linux that actually worked with no problems.

Hi.
On Linux Mint 17.2 or 17.3 when I try to use GRUB method I recieve error message after try to update GRUB !! I follow instructions above & change variables in configration file then “save” changes. But when I use:

sudo update-grub
then I recieved error message !!

I try sudo update-grub2
but It is not available !! Are you sure it is grub2 not grub ? I think it is just grub

I try to invistigate this by just type in terminal:

grub

to see what output. Then I recieved message say “grub not installed” & command me to use:

sudo apt-get install grub

What is this?

Please your kind reply.

It’s suffice with just net.ipv6.conf.all.disable_ipv6 = 1
That will automatically imply net.ipv6.conf.*.disable_ipv6 = 1

Edit /etc/gai.conf and uncomment the line to prefer ipv4 over ipv6.

Which is the correct way to deal with this.

This does not work for me. $ sudo gedit /etc/default/grub. Will not recognize $ sudo. I’m running Mint 17 KDE. I was able to bring up the command to notice that I have the ipv6 running; but my ISP and the modem is not running it. How should I disable it in KDE?
