Overview You know it, you hate it; this is a real kicker of an issue that prevents web-browsing properly and causes any apt-get operation to take forever. This is an IPv6 related issue; IPv6 is a garbage protocol that renders usage of a VPN ineffective; IPv6 holds your exact physical location as well which makes it highly undesirable. Let's work on disabling it. How2 First open Scratch as a normal user and create a new file; if a sudo operation happens before Scratch is opened as a normal user it will create a blank file that only a root user can access rendering Scratch broken. Issue the following in Terminal: sudo scratch-text-editor /etc/sysctl.conf add the following lines at the bottom of the text file: # Kill IPv6 for the session net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 After saving the file, issue the following in terminal: sudo sysctl -p This will disable IPv6 for the entirety of the session; to re-enable IPv6 restart your PC. Regretfully you will need to issue "sudo sysctl -p" in terminal after each restart to keep IPv6 dead, but some people may situationally need it so...
