how to install programs in an installed kubuntu system through kubuntu live usb/cd ?

[radiobert]

I am in a big trouble...
Accidentally I 'apt-get remove' a lot of essential packages needed by the KDE, as a result, window-related problems appear...I can't make the windows to be focused, so I can't even type a character into the konsole to reinstall the packages back.

The idea to mount the filesystem and then install the packages using apt-get through Livecd /liveUSB come to my mind, but the question is, can this method work? If this is a feasible method, how can I do it?

For those who like to know what I have removed, see the list below:

It might work, but in that case you are installing old packages (from the CD) into an updated system. You could end with a lot of trouble with dependencies.

Maybe it is best to reinstall. It takes one hour and is guaranteed to work on your hardware.

Hi and welcome to the forums :popcorn:

Morgaes suggested a reinstall. Still you can try to boot into recovery mode. You can do this by holding down Shift as soon as the computer gets past the bios screen. Try


sudo apt-get update


sudo apt-get install -f


sudo dpkg --configure -a

Finally I found myself a solution to the problem ---use chroot...
What a nice day I have had....
