This is really a basic test, and if your networking is connected and working properly, the only reason this should fail is failure to reach a specified website.
and one other question,
do you happen to have both ethernet and wifi connected to the same network at the same time? there's a SLIGHT chance that that could cause connection problems (I've observed that before myself, but rarely).
So the command is running, but fail to establish a simple connection. The test is hard-wired to connect to http:// cdimage. ubuntu. com.
Can you do a couple things:
1: run the attached script from a terminal twice, like so:
./network_check -a; echo $? www.google. com -a; echo $?
./network_check --url=http://
and let us know the results.
2: if the first one fails (the attempt without the --url), can you try the following:
ping cdimage.ubuntu.com
or try opening http:// cdimage. ubuntu. com in a web browser.
