In the beginning I had set a password to login into the system, then I removed it because every-time when the screen used to blackout, I had to type the password.

Now, I can't open synaptic package manger. It asks for the password, if I type the password it does not accept it, if I do not type anything and just click "authenticate" still it does not let me in.

I had to do this as there is a red color circular icon on top right corner, it says "An error ocurred, please run package manger...."

when I click on "install all updates" it says "package system is broken"

How can I install all updates and why package manger is not accepting the password, I am logged in as Admin.

  • How did you remove the password? – danzel Mar 16 '18 at 9:51
  • @danzel, system settings > user accounts – Vikram Mar 16 '18 at 9:52
  • So you activated the "Automatic Login" option? If so, your user password shouldn't have changed. Please try entering sudo echo into a terminal ([Ctrl]+[Alt]+[T]) and see if your password is accepted. – danzel Mar 16 '18 at 10:03
  • @danzel, tried, it does not accept, says "sorry..." – Vikram Mar 16 '18 at 10:08

    You can reset your password and see if that helps. – danzel Mar 16 '18 at 10:43
