I installed Ubuntu 17.04 on a Toshiba Satellite L500 and I can't connect to the internet even though the computer connects the network via wifi.
I tried changing 'method' to 'ignore' on the IPv6 definitions tab in the edit settings dialogue of the wifi network I'm using; after rebooting it worked but now it's not working again. I also uncommented line
precedence ::ffff:0:0/96 100 in /etc/gai.conf but it didn't worked. I also tried to run
apt-get update but it failed with
W: Some index files failed to download. They have been ignored, or old ones used instead; oddly
apt-get upgrade worked. Can you please help me?
It's very strange, the internet connection keeps failing for some minutes once in a while... Why does that happen?!?
Apparently the problem was the server I was using. I changed it and now it works.
Oddly enough the internet is now working again; however
apt-get update isn't.
