software-center interview questions
Top software-center frequently asked interview questions
In Ubuntu, once a release is out the software one has installed receives security updates only. In Windows, I can get new versions of programs with new features. How can Windows do this and why can't Ubuntu?

How can I set the Software Center to allow non-root users to install stuff from the Ubuntu repos without having to type in their password?
I'm fully aware of the security implications, and I am willing to take the risk. Fedora 12 shipped with something like this. (By modifying the PolicyKit configuration, I believe)

In Ubuntu Software center there are different sections for programs
- Provided by Ubuntu
- Canonical Partners
- For purchase
I know all of these are open-source; but is there any validation process done by the Canonical to ensure that they are free of any spyware or malware?
I wonder will anyone get time to look at all these (2355 programs or so as of now), software code that too for every release!!
I am worried because I routinely install rather unpopular software from software center :)

Many questions are answered simply with add this repository and install.
I understand that Ubuntu developers cannot quickly verify all packages and make them available in official repositories. But is there an unofficial main repository or software center where developers can register their PPAs?
Adding individual repositories is a pain and the update also takes longer as it has to check all the PPAs. Like we have alternative markets for android, it would be great if there are any popular alternative software sources that we can reasonably trust.

I'd like to access entire contents of the Ubuntu Software Center online. Is there anyway to browse the Software Center online?

Any install that I'm trying through the Software Center is telling me:
Requires installation of untrusted packages: The action would require the installation of packages from not authenticated sources.
I did an apt-get update from the command line, then removed the software sources that the keys were bad from (PPAs I added myself), and unchecked them in the software sources for software center, but to no avail. I can't install anything from software center anymore - only> from the command line with apt-get.
Is uninstalling/installing the only option? I don't want to break other PPAs that I have.
Additional information:
Here's a paste from apt-get update:
Reading package lists... Done
W: GPG error: http://ppa.launchpad.net oneiric Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B725097B3ACC3965
W: GPG error: http://us.archive.ubuntu.com oneiric Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>
I've tried apt-key update, and there was no effect (two keys unchanged).
The output of apt-get update and apt-get upgrade, and the contents of /etc/apt/sources.list, can be found in this pastebin post.

This bug has now been fixed upstream. An update has been issued. If you still cannot install, ensure you have updated fully, and then restart your computer.
I am trying to install downloaded DEB packages. Each time, I see a warning like this:
And clicking install just loads and nothing changes.
This shows for all the packages I try and install. How can I install a package?

When installing applications via the software center or by a DEB file they will usually be installed system wide for all users.
Is there a way to install an application for a single user only?
