[kubuntu] Trouble installing or updating software in Kubuntu 12.04

http://ubuntuforums.org – I just installed Kubuntu 12.04, and I've been trying to install updates (with Muon Software Updater) or add software (with Muon Software Center). However, most of the time both programs fail to ask for a user password before installing and then an error comes up saying the operation failed because I didn't provide authentication, even though it didn't ask for a password. Any help is appreciated. (Hardware)

The update manager is no longer prompting me for a password to update files? It's not a real big deal since this is a single user system but it seems like a major security flaw btw i'm using the updated muon software center & muon updater through https://launchpad.net/~echidnaman/+archive/qapt

How to prevent Muon from asking a password when installing updates? Adding "user ALL=(ALL) NOPASSWD: ALL" to sudoers does not help. "sudo apt-get upgrade" works without a password, but Muon is still asking for it. It is very annoying to enter password every day to install updates. (Kubuntu 12.04)

On a recent clean Kubuntu 11.10 64 bit install, Muon Package Manager and Muon Software Update Center would not work. I would just get a bug report. I had to do all the updates through Konsole. The only way I could get Muon to work was install an experimental version of Muon through a PPA, ppa:echidnaman/qapt-experimental.

I am using Kubuntu 12.04,currently.Recently ,I updated my system with update manager and downloaded USC from muon software center which was pre-installed in this system.

apt-get broken on kubuntu 12.04 17 weeks 9 hours ago

I just wanted to add my little stone, so I tried to do an install of "wine" on a Kubuntu installed on my laptop (amd64 quad proc, 12.04, strictly and regularly updated and maintained) which leads directly to a load of apt problems.

After some updates, Muon Software Center started crashing when I try to start it.

i have kubuntu today after updating the muon package manager stuck at 64% so i closes it. and after that when i try to update or reinstall or install software the manger stuck. so how can i reinstall the muon package manger from terminal??

i try

sudo apt-get install muon

and i get this messege

Reading package lists... Done Building dependency tree Reading state information...

I have noticed that Kubuntu (I am using 12.04 version) doesn't use exactly the same repositories that Ubuntu. Or at least, that is what I think. For example, if I search for Steam on Muon Software Center or Muon Package Manager, I just can't find it; even if I use sudo apt-get install steam-launcher. But on Ubuntu I have no problem.

Software center from kubuntu 30 weeks 6 hours ago

I was trying to install pysdm on my kubuntu when i saw that i couldnt found it in software center, but in ubuntu software center it is.

Shouldnt kubuntu have repositories from ubuntu, it is in ubuntu's family?

If no, how can i get ubuntu repository in kubuntu software center?
