[SOLVED] Impossible to launch ... as root.

Postby yashletn » Thu Jun 13, 2013 11:33 am

Hi,

When I click in the menu to launch the Software Manager, this message appears:
Image

In (my poor) english:
-----------------------------------------------------------------------------
Impossible to launch mintinstall as root.
Communication with gksu-run-helper failed.

Received:
su: authentification failed
What was expected:
gksu: waiting
-----------------------------------------------------------------------------

I logged as user or admin: same problem??
I've been searching for hours on internet but no solution yet.

Help!

Note that when i open a terminal and write: sudo mintinstall
It works perfectly!

I have the same problem with synaptic and a fiew other applications.
I think this problem started when, one day, i choosed admin in the users panel (curiosity or stupidity?).

yashletn,

I'll take a stab at this :!:

Open a terminal end enter

Code: Select all

sudo mintinstall&

and paste back the messages in the terminal.

OK, so I'll assume that mintinstall launched and you were able to use the application normally.

Next try

Code: Select all

gksu mintinstall&

and paste back the messages.

Make sure you're using your user account and not root!

yashletn,

Do you get that "Impossible to launch message 'after' entering the password :?:

If so, are you using your account password that you would use for sudo :?:

gksu uses su as its backend for running the program so you would need to use the root password - not your account password.

Try gksudo mintinstall& with your account password and see if the same thing happens. That should be the same as running sudo in the terminal.

Yes, the message "Impossible to launch..." appears after entering the password.
I use the same password as for sudo... or any operation:
i have only one password.
i don't remember having another password for root ??

so:

Code: Select all

gksudo mintinstall&

terminal answers:

Code: Select all

1. a window asks for password.
2. i enter my password (the only one i know).
3. the software manager appears.

As a matter of fact I installed Mint 15 (Olivia) to take a look at it and it didn't ask for a root password, but I always set one.

I don't understand why mintinstall uses gksu rather than gksudo and the install process doesn't ask to setup the root user password, but it is what it is.

To fix the menu launcher just set a root password and use that when you launch mintinstall.

In the terminal enter:

Code: Select all

sudo passwd root

then the password. It will ask you to verify it so enter it again then try to run mintinstall from the menu and use the password you just entered.

Good luck :wink:
