Is there a problem with unetbootin?

[michel]

I tried to use unetbootin but I was asked for my administrative password and when I enter my root password I get an error. I re-installed using synaptics and get the same error. Is used to work fine.

Thanks,

Michel

You don't need the root password. Just use your normal password if you are in the sudoers group.

[michel]

Thanks. I use the same password for both.

Thanks. I use the same password for both.

Michel

Ah ok. Might you explain why you enabled the root account? Its very abnormal for people to use it, especially in Ubuntu and its derivatives like Kubuntu.

[michel]

Sorry for the confusion. I was entering my user password. I get confused because it is the same one.

Have you tried running Unetbootin from the command line withe kdesudo/kdesu? What is the error?

[michel]

This is the error I get:

michel@michel-Satellite-L650:~$ sudo unetbootin
[sudo] password for michel:
Error: "/var/tmp/kdecache-michel" is owned by uid 1000 instead of uid 0.

Thanks,

DO NOT RUN GUI APPS WITH SUDO! It can cause problems.

[michel]

OK but if I run unetbootin as a user I get the screen asking me for the password (three times) and then an error message same as if I was launching the application from the menu.

I found this information it recommends adding kdesu before the command line /usr/bin/unetbootin. It works as with sudo but before marking the subject "Solved" I need to know:

- If unetbootin is working properly (I am having problems creating a bootable USB)
- Why was it working perfectly before without kdesu?

Thanks,

[b]kdesudo[/b] [i]some-GUI-program[/i]

is perfectly fine.

[b]sudo[/b] [i]some-GUI-program[/i]

is to be avoided.

[michel]

Got it Sudo will use root privileges but might use user's profile and could lead to problems. But why did I have to add Kdesudo to the command line in the first place when it used to work fine without it?

Thanks,

Michel

This is a bit weird, as unetbootin normally self-elevates. Try something for me. At a command prompt, please run

unetbootin

This is without any other command preface. Presumably, you'll still see the password prompt you describe in post #9. Just leave it on the screen.

Next, open another command shell and run the following:

ps -ef | grep unetbootin

Reply here with everything you see from the output of that command.

In order to be able to enter the command into the other shell, I had to enter passwords on the unetbootin form to get access to the new shell. results as follows:

michel@michel-Satellite-L650:~$ ps -ef | grep unetbootin
michel   21174     1  4 10:51 ?        00:00:01 /usr/bin/gksu /usr/bin/unetbootin 'rootcheck=no'
michel   21194 21097  0 10:51 pts/2    00:00:00 grep --color=auto unetbootin

Thanks,

Hm. Yours is starting with the GNOME graphical sudo, not the KDE one. Here's mine:

steve@t520:~$ [B]ps -ef | grep unetbootin[/B]
steve    17816     1  2 10:18 ?        00:00:00 /usr/bin/kdesudo /usr/bin/unetbootin 'rootcheck=no'
root     17821 17816  0 10:18 ?        00:00:00 /usr/bin/sudo -H -S -p passprompt -- /usr/bin/unetbootin rootcheck=no
root     17822 17821  1 10:18 ?        00:00:00 /usr/bin/unetbootin rootcheck=no

I wonder why gksu is installed on your system. Perhaps it's the problem, but I doubt it. Let's find out why you have it, though. We'll simulate an uninstallation, and this will tell us whether something else on your computer requires it:

apt-get -s purge gksu

Reply here with the output of that.
