Wi-Fi WPA2 Krack Attacks already fixed in Ubuntu 16.04 LTS

October 16th, 2017

This day had some shocking news in the morning. All Wi-Fi devices were unsafe! A serious weaknesses in WPA2, a protocol that secures all modern protected Wi-Fi networks was discovered by a Belgian security researcher.

In particular Linux and Android devices were vulnerable.

Bad news. But Ubuntu rolled out a patch and fixed the vulnerability already today.

So running this commands will make your device safe again:
sudo apt update
sudo apt upgrade

Before the update:

wpasupplicant/xenial,now 2.4-0ubuntu6 amd64 [installed]
client support for WPA and WPA2 (IEEE 802.11i)

After the update of today:

wpasupplicant/xenial-security,now 2.4-0ubuntu6.2 amd64 [installed]
client support for WPA and WPA2 (IEEE 802.11i)

Changelog for the update

Happily running Ubuntu!

I would love to run Linux on my Phone.

    It’s a shame the Ubuntu Phone died, but hopefully we’ll get a GNU/Linux phone soon: the upcoming Librem 5 Smartphone.
