Neglect the http typos, its to evade the 2 hyperlink..

I tried making a file in the apt.conf.d folder also, and added proxy entries, also set the system proxy.. and also the "network proxy", but nothing works..

And now I cant install any software!! Help needed

is this a fresh,clean installation or did you just upgrade from any other version of Ubuntu? are you using 32-bit or 64-bit architecture? –  Ankit Aug 15 '12 at 5:59
    
Try changing the software source to some other mirror, may be it'll help. –  TheKojuEffect Jan 30 '13 at 9:22

Double check your internet connection, make sure that it is indeed working. I noticed that you mentioned this was a fresh installation.

Take a look here

I dont think thats the problem.. coz I checked the internet part.. What about "A hash mismatch is usually a sign of a broken mirror" –  user53209 Apr 3 '12 at 6:32
