Sometime ago Ubuntu decided to replace ‘Synaptic’ (extremely popular software package manager used heavily in ‘Debian’ based distributions) with their ‘Ubuntu Software Center’. It has always been a bit more user friendly, but ‘power users’ don’t like it that much because it doesn’t come with a lot of options as ‘Synaptic’ which gives you more control over installed applications.
Another reason (apart from all of its features) why I didn’t like it because it used excessive amount of RAM while running. However, recent versions of Ubuntu Software Center is doing pretty well it seems as when comparing with ‘Synaptic’, at the initial launch, it used almost the same amount of RAM and even when I searched for apps etc it still didn’t use memory excessively.
But I still prefer ‘Synaptic’, again because it gives few more options that I usually need (such as downgrading to older version of a package) and it gives more results when searched for applications as well.
Anyhow, if you’re a fan of the Ubuntu Software Center, and looking for a way to get the latest ‘builds’ (daily updates), so you can get a taste of the new features (and bugs! ) before it’s ported into the system updates, then you can use its official PPA for that.
However, please remember that, this PPA includes the daily builds, which might be dangerous for some as it could include unstable packages, so please use it at your own risk as there is the possibility of it breaking your Software Center.
To get the daily builds enter the below commands in your Terminal (this should work in Ubuntu 12.10 Quantal Quetzal, 12.04 Precise Pangolin, 11.10 Oneiric Ocelot, 11.04 Natty Narwhal and 10.10).
sudo apt-add-repository ppa:software-store-developers/daily-build
sudo apt-get update
sudo apt-get install software-center
That should do it. Enjoy!.
