Help with sudo and su

[BobRon]

Hi.
I need to uninstall some software using a sudo command, but when I type the admin password, it doesn't work!
I try doing:

sudo su

with the admin password, but it says

Sorry, try again.

I enabled root user and try

su

but it also says

su: Sorry

I repaired disk permissions and everything BUT IT STILL DOESN'T WORK!!

Yes, the admin is the original account created with this mac

to use sudo, you account needs to be 'allowed to administer'

su can be used to switch to any user,

su shortusername -


to switch to root, you can use

su -

or

sudo su -

sudo uses your password not the root password.

Any reason you don't just use sudo rm <files> ....?
As said, the password must be valid for an admin account.

I enabled root user

If you enabled the root user, and logged into it, then you should be able to delete anything anything without using sudo. Root has access to everything.
Make sure you disable the root user when you're done.

Repair Permissions rarely does much. If a genuine admin account password doesn't work, sounds like the sudoers file has got corrupted somehow.

well, i manually edited the sudoers file to include a different admin specifically, and it worked! But i can't use my current original admin account
