Unable to lauch the Updates...New Installation of Kubuntu...
 

I am new at Linux and I have recently installed KUbuntu on two computers and there is a message that says that there are Updates, the first one is Security Updates, then there is a list with all the check boxes checked. When I click on the green check mark to lauch the Updates, the computer freezes up and I do not know what to do but to reboot (cold boot). The same thing happens afterward.

Thank you

Open up a terminal (Konsole) and type there
hit enter then type your password and hit enter again

let it do its thing but once its done type
type your password if prompted
let it do its thing once its done type
hope that helps you to fix some bugs or whatever missing drive gets installed.

good luck to you

You might also check the contents of your /etc/apt/sources.list file.

On the most recent two installs of Mint I've done (an Ubuntu based distribution) I found the sources.list file just referenced the install media. If that's the case, just grab one off of the Internet and do the above poster's suggestion.
