I've installed Ubuntu 12.04 LTS, both on My laptop and Desktop PC.
I've run
sudo apt-get update
on both of the platforms. In my PC I can install these packages by searching in "Synaptic Package Manager":
build-essential
cmake
ant
jdk7
.....
but in My laptop I cannot find theses packages in "Synaptic Package Manager". I've installed both of the operating systems from the same .iso file.
Why in my laptop I can't find most of the packages that I find in My PC ? is there something wrong with my repositories ?
/etc/apt/sources.list
files on "My PC" and "My laptop"?
