  3. If you have a user with sudo rights (by default in ubuntu, you first user will have this right)
    just type this:

    sudo passwd root

  4. hi ubuntu 10.10

    not able to hit escape on boot up. Can not get to root. I can log in as administrator. I can not get to root using sudo. It says there is a problem with the sudos file. This happened when i installed the latest ubuntu updates

    All I can do is switch it off and then on. The only option is to reload, ubuntu.

  8. I use Mint Linux (based on Ubuntu), but the above solution to get a root shell without password doesn’t work.

    The system restarts, I use the arrow keys to choose “recovery” and type “e”, well I can edit the kernel-line and add “init=/bin/bash” but if I press ENTER, a new line is added. If I press ESC all changes are gone and in the menu “b” has no effect.

    What’s the corret way to change the start up of current grup version?

  11. In Ubuntu 10.10 I went to very end of the line and added rw init=/bin/bash and now ubuntu seems to start up normally at first untill after the plymouth booting animation theres only a purple screen. When I logging through safe-mode theres a problem with the encryption manager. My home folder doesn’t get decrypted and because of that nautilus and gnome lack functionality.

  13. When i do this, passwd_space_user_space_password, I get to a “help desk”. It says : root@(none) :/# usage: passwd [options] [login]

    Options :
    And certain commands. I try to write my new password (not sure if its the timing to do it) and write reboot.
    I get the “error” saying shutdown: Unable to send message: connection refused.
    Can anyone help me from here? btw, 15 yrs old so this is pretty new. I have Vista (black screen of death before everything) so I try Ubuntu.
