  • check /etc/apt/sources.list, this is the file that contains the repository list. check this link: https://gist.github.com/jackw1111/d31140946901fab417131ff4d9ae92e3 it contains the default repository list for Ubuntu 18.04. Copy the content to /etc/apt/sources.list – singrium Nov 09 '18 at 10:58
  • The terminal cannot install or execute anything. – Jean Dedieu Rwasa Nov 09 '18 at 10:58

    The command is wrong, post the output of: sudo apt update – abu_bua Nov 09 '18 at 11:15

Run sudo gedit /etc/apt/sources.list
Delete all the content you find in this file and Copy this to the file:

  • it requested to continue by the command below "Do you want to continue? [Y/n] y" and then the last line says "Processing triggers for libc-bin (2.27-3ubuntu1) ... Is there anything else before i close????? – Jean Dedieu Rwasa Nov 09 '18 at 11:17
  • Yes, after running sudo apt update, you will be asked to type you r password, then it will do the update. It is the same for sudo apt upgrade too: type your password then enter – singrium Nov 09 '18 at 11:19

    @JeanDedieuRwasa Please read the "Posible duplicate" above and ignore this answer. Two reasons: (1) It tells you to do a dangerous operation - running graphical apps with sudo and (2) instead of solving the actual error mentioned it goes the easy way of reseting the repositories to the default ones ignoring if you have and need any others. –  Nov 09 '18 at 11:20
  • If it asks you to continue, press 'Y' key, then update and upgrade will be done – singrium Nov 09 '18 at 11:20
  • I agree with @GabrielaGarcia, this answer is the easy way to do it. but it is effective and solve the problem. If you want the complicated way, follow the steps explained in the 'duplicate' link. – singrium Nov 09 '18 at 11:23

    @singrium You should also notice a fundamental difference: The duplicate uses sudo -H. Again, using sudo with graphical apps may result in changing permissions in the user space, a way more complicated problem than the one we're dealing here. –  Nov 09 '18 at 11:25
  • Thank you so much guys for helping me. It is now working – Jean Dedieu Rwasa Nov 09 '18 at 11:29
