how to login as root on Ubuntu 8.04 LTS (Hardy Heron)

Hello everyone

i try to login as root on Ubuntu 8.04 LTS (Hardy Heron) with: su

the terminal retrieves: su: Authentication failure


for sudo it retrieves:

sudo: unable to resolve host named-desktop
usage: sudo -h | -K | -k | -L | -l | -V | -v
usage: sudo [-bEHPS] [-p prompt] [-u username|#uid] [VAR=value]
{-i | -s | <command>}
usage: sudo -e [-S] [-p prompt] [-u username|#uid] file ...


Any sugestions=?

Thanks in advance,

: respect :

 

Ubuntu comes with disabled root account by default so You can log in after giving root a password:

Code:

sudo passwd root

and entering the password of the first user added to the system.

Keep in mind that You don't have to enable root account to have root privileges.You can use sudo instead.For example:

Code:

sudo [command]

will execute a command after entering the password of the first user added to the system.

Code:

sudo su

will let You have root privileges without typing sudo all the time.

 

ok many thanks ;- )

its seems to work though i still get some errors...

for example, for file share configuration i get this screen bellow



Any sugestions for this? How should activate the "Administrator Mode" button?

Thanks and best wishes

 

Is it possible that the "Adminsitrator Button" is hidden because the window is too small? Can you enlarge the window?
