After installing 12.04 Ubuntu I tried to install Kile but when I was trying to install Kile , it showed that "failed to download package file . Check your internet connections" . But my INTERNET is working properly even I can download updates available . How can I solve this problem ?
Still trying to install it but it says " Failed to download package files .Check your Internet connection. , Failed to fetch http://bd.archive.ubuntu.com/ubuntu/pool/main/v/virtuoso-opensource/virtuoso-opensource-6.1-bin_6.1.4+dfsg1-0ubuntu1_i386.deb Size mismatch "
There is no problem in INTERNET browsing so where is the problem ??
