I tried asking many times on few Ubuntu forums how to deal with my non-responsive Update Manager, but all I was getting was the same stuff (run it from the terminal, run some lines, apt-get update blah blah). Nothing was helping. Eventually I went mad Windows style and tried to simply uninstall it and install it again. The problem is - how to install it again? Can't do it through Software Center, can't really build a package (because I'm too stupid to do that). And I seriously want to avoid reinstalling the whole system.

I am running a 12.04 version (Update Manager was unable to update to a newer one)

How did you uninstall it? – Yet Another User Jun 12 '13 at 19:36
Also, what happens when you open a terminal (CTRL+ALT+T) and type in sudo apt-get -f install? – Yet Another User Jun 12 '13 at 19:42
how (what commands did you use???) did you uninstall it through the terminal??? – Yet Another User Jun 16 '13 at 14:32

If you're having trouble with a package and you choose to completely re-install it, you should first completely remove it.

 sudo apt-get --purge remove update-manager

will remove the update manager and any configuration files it's created. If there is a configuration error, this will allow you to re-install fron scratch.

Of course, you'll lose all the configuration files, and I'm not sure what this might do. I don't know if those configuration files detail everything installed on your system, and whether you might end up with a butt-load of hurt when your next install can't tell what dependancies are already installed. I could be worried over nothing . . . but I'd wait for a wiser brain than mine to comment.

sudo apt-get install update-manager synaptic


sudo apt-get install --reinstall update-manager synaptic

what does the commands do in detail? Why do you have two commands? – Alvar Jun 12 '13 at 19:47
sudo means "superuser do", requiring administrative rights and password to change the system. apt-get is how Debian-based Linux downloads and installs software from online repositories. install means what it says, as does reinstall. update-manager and synaptic are packages apt-get is being told to fetch and install. – Marc Jun 13 '13 at 1:47

I had a problem with update manager so I uninstalled update-manager and installed again by using:

For uninstall

sudo apt-get purge update-manager

For install

sudo apt-get install update-manager synaptic

And just worked

Sorry for my spelling
