I'm trying to install software by using apt-get and ubuntu software center UI, when I try the ubuntu software center it gets stuck saying installing and installs nothing and when I try the apt-get it gets stuck at the point "0% [Waiting for headers]"
I tried modifying sources.list file. I installed ubuntu this morning. Do you have any suggestions for me ?
Thanks in advance for your time.
edit : After a while, I get the error 502 bad gateway
