Why apt-get update fail to connecting to dl.google.com?
When I have this problem, I disable IPv6 in Ubuntu and that fix the problem, in order to do that, please follow these steps:
To disable IPv6, you have to open /etc/sysctl.conf
using any text editor and add the following lines at the end:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
If IPv6 is still enabled, then the problem is that sysctl.conf
is still not activated.
In that case, open a terminal(Ctrl+Alt+T) and type the command:
sudo sysctl -p
The output will be very similar to these 3 lines:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
After that, execute:
$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6
If you see 1
in the output, then IPv6 has been successfully disabled.
1
Hope this helps.
