When I'm about to install a program in the terminal it wants the password:  [sudo] password for xxx:   But when I start to type my password nothing happens. What should I do?

I forgot my root password...actually I think I know what it is because it is the same password I have for pretty much everything but in the Terminal in tell me "Sorry, try again." Is there a way to reset the password? If so how?

I notice a weird (well, according to me) thing about passwords. For example, if I type an incorrect password during login, there will be a few seconds' delay before the system tells me so. When I try to sudo with a wrong password I would also have to wait before the shell says "Sorry, try again".  I wonder why it takes so long to "recognize" an incorrect password? This has been seen on several distributions I use (and even OSX), so I think it's not a distribution specific thing.

There's been one problem I've had since I installed Ubuntu to run alongside Windows, I assume this would also be the same if it was installed to replace the other operating system as well, the installer prompts you to create a password upon typing in the user account name and if you don't put in a password and just put in the user account name, it ends up saying to create a password. My comparison is in Windows and Mac OS X, you are never forced to create a password.  If you remove the password on your Admin account in System Settings > User Accounts, you won't be able to authenticate whenever you try to install something, because it requests for a password and putting in no password at all isn't going to work, it will just act as if you put in an invalid password. This is what I call "getting locked out of privileges".  I'm finding the "Authenticate" window that comes up whenever you install something or accessing somewhere a nuisance, 'cause it always requests for your password.  So my question is - Why does Ubuntu force users to create a password upon installation?

I get error message always when I work with sudo command.  It shows always sudo: /var/lib/sudo writable by non-owner (040777), should be mode 0700.   A while ago I changed the permission of /var folder to 777.   How can I fix it?

I just bought a new laptop with ubuntu installed on it. When i first turned on the laptop ubuntu started with an error and restarted. Then when it turned on again i only had the guest session option. I've tried, but i can't use sudo in the terminal: Sudo: unable to change to root gid: operation not permitted Sudo: unable to initialize policy plugin I tried the recovery path too, but i don't have a username and can't do anything. I can only go in guest session. Please help, sorry if this is something obvious to do, it's my first time opening ubuntu.

After I read  I noticed that there is a user account named 'nobody' in my Ubuntu system.   Also I noticed that I can login in this account from terminal using the following command and my password:  sudo su nobody     It doesn't mind me at all, but I want to know what is the purpose of this user? Is it created by default on a fresh install of Ubuntu or is created by installing a particular package?

To run programs as sudo without password, I edited /etc/sudoers with wrong content.   Then I re-edited it with Mac's default text editor(course sudo cannot be used when /etc/sudoers is wrong).  I tried to run sudo agin, and get this error:   sudo: /etc/sudoers is owned by uid 501, should be 0 sudo: no valid sudoers sources found, quitting   What should I do? I cannot remember the root password (maybe I haven't ever set root password before).

Whenever I issue command sudo apt-get install foo it does not ask for password. is it because of user groups?  How to make it prompt for password?

On one particular machine I often need to run sudo commands every now and then. I am fine with entering password on sudo in most of the cases.  However there are three sudo commands I want to run without entering password:   sudo reboot sudo shutdown -r now sudo shutdown -P now   How can I exclude these commands from password protection to sudo?

We are having a little problem on a server. We want that some users should be able to do e.g. sudo and become root, but with the restriction that the user can't change root password. That is, a guarantee that we still can login to that server and become root no matter of what the other users will do.  Is that possible?

I would like to know what is the difference between    su - sudo bash sudo sh   I cannot login as root while doing su - because I do not have the root password - I mean I have my user password with which I can sudo "command"  but this password does not work for su - I can log in as root with sudo bash with my user password and I can login while doing sudo sh but then I get a command prompt in this form #

On my personal machine, I often type sudo in front of certain commands in order to accomplish administrative tasks.  I had hoped to avoid doing this throughout the day, by typing su root and providing the same password I usually do for sudo.  However, the two passwords are not the same(I don't know how to log in to su root).  Is running a command with sudo different than logging in with su root and running the same command?  I think sudo and su root are the same, because when I type sudo whoami, I get root, as opposed to just whoami where I get my user-name.

Why  do we use sudo to perform a terminal command as an administrative? Why isn't it  admin or something else? Is there a reason for sudo?

I just powerwashed (that's a factory reset on chromebooks) my computer so that it would be be 'brand new,' however now I don't have sudo access anymore. I used to not need a password to use sudo, however now a password is required and I have no idea what it is. I tried my login password, however that didn't work. Any advice?
