I've installed Ubuntu 12.04 LTS, both on My laptop and Desktop PC.
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 ?
