I was using Ubuntu 12.04. But today I just made format my system and installed Ubuntu 13.04. I have made copied the archive file (/var/cache/apt/archives) from Ubuntu 12.04 and made paste to 13.04 . After I made the system update by doing commands (sudo apt-get update) terminal. Then after that whatever I am trying to install on my system it is showing error like
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package package-name
Even I tried to install apache server by using sudo apt-get apache2. It is showing the error like
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package apache2
So can someone kindly tell me how to solve this issue. Any help and suggestions will be really appreciable. Thanks
