connecting to archive.ubuntu.com takes too long
I have a Ubuntu 13.04 that I just installed fresh. Now if I try to do anything with
apt-get, it tries to connect to
archive.ubuntu.com .. It stays at
[Connecting to archive.ubuntu.com (2001:67c:1360:8c01::1a)] phase for like 2 minutes, after which it actually starts to communicate and download stuff …
Eventually it always connects, but in waits at the
[Connecting to archive.ubuntu.com (2001:67c:1360:8c01::1a)] phase everytime for like 2 minutes !
I didn’t have this problem previously on Ubuntu 13.04, right after reinstalling the OS ..
I figured out the problem. Posted below as an answer!
Running the following command in Terminal tells if IPv6 is enabled or not:
0 means its enabled, while
1 means its disabled.
To disable IPv6 from within Terminal, enter the following and reboot:
echo "#disable ipv6" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
After boot, re-run the first command, and it should be
1 now, after running this run
sudo sysctl -p
all output should be 1, now ipv6 is disable here.
