failed to start Light Display Manager

Question

I am very new to Ubuntu. I am getting failed to start Light Display Manager error when I start Ubuntu. I am not getting login page. It might be possible that I have deleted Lightdm package. Can I download it again using any command with proper link? It is not available in computer so I could not install it.

You can install lightdm with this command sudo apt-get install lightdm though! — arximughal, Dec 06 '18 at 13:14

Check to see if you have lightdm installed:

lightdm -v

Install lightdm from your terminal:

sudo apt-get install lightdm

PS: Ctrl+Alt+F1 should grant you access to the console even if you do not have any screen icons

Fwiw apt-get is deprecated in favour of apt. – pbhj Dec 06 '18 at 15:19

After installing lightdm, if you want to setup lightdm default, use sudo dpkg-reconfigure lightdm, click OK and select lightdm. ref – arximughal Dec 06 '18 at 17:09
Thankyou sir, after following your suggestion i am getting fooling error: – shah milan Dec 06 '18 at 18:20
I got this during install : " package lightdm is not available,but is referred to by another package.this may mean that the package is missing,has been obsoleted,or is only available from another source. " – shah milan Dec 06 '18 at 18:25
Be sure to apt-get update – Samuel Anyaele Dec 18 '18 at 11:59

If the result is [offline], you probably should use an ethernet cable to connect to the internet.

If you see [online], you can continue.
