I am using Ubuntu18.04.2LFS.

I moved to another office, when I typed python in firefox and searched, there is some errors. I can't search. I tried Google, but it doesn't work, too.


However, I can open the page like ask ubuntu.

In other words, I can open the link, but I can't search with firefox and google.

Any ideas? Is it about the wifi ? What can I do to make it working again?

    Try connecting other machines to the same router and see if it's a router problem or a pc problem. Then if it's a pc problem try pinging the websites that don't work and pinging their ip addresses, if the the ip addresses work but website don't, then you have a dns problem. – Reda Drissi Jul 12 at 14:02
  • Of course it's a PC problem, since I can open the link. – Ji Tiantian Jul 12 at 14:20
  • Can you open the page google.com ? – Reda Drissi Jul 12 at 14:42
  • For a long shot apt-cache policy libsqlite3-0 – nobody Jul 12 at 16:55
  • Can't open the page of google.com. It seems it is the Chinese government that stop it since my friend can't open it either. – Ji Tiantian Jul 14 at 10:18
