IPv6 needs to be disabled before PPA install

[dennis-george0]

Describe the bug

IPv6 needs to be disabled before PPA install.

For some reason a clean Ubuntu install will try to push IPv6 to pull the Kobuk Team PPA. Disabling it within the common settings does not help as it is still reinforced and gives you "connection time out" errors.

Can be fixed by using the below:

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

Disconnect the network adapter and connect it back again.

Would be useful to have this stated somewhere in the instructions.

How to reproduce
Steps to reproduce the error:

1. Clean Ubuntu install
2. Follow the Linux B580 installation steps
3. Install the Kobuk-team PPA
4. Get connection time out error [Errno 110]
