pooky2483@pooky2483-ubuntu12:~$ gksudo apt-get -f install gksudo: invalid option -- 'f' GKsu version 2.0.2 Usage: gksudo [-u ] [options] --debug, -d Print information on the screen that might be useful for diagnosing and/or solving problems. --user , -u Call as the specified user. --disable-grab, -g Disable the "locking" of the keyboard, mouse, and focus done by the program when asking for password. --prompt, -P Ask the user if they want to have their keyboard and mouse grabbed before doing so. --preserve-env, -k Preserve the current environments, does not set $HOME nor $PATH, for example. --login, -l Make this a login shell. Beware this may cause problems with the Xauthority magic. Run xhost to allow the target user to open windows on your display! --description , -D Provide a descriptive name for the command to be used in the default message, making it nicer. You can also provide the absolute path for a .desktop file. The Name key for will be used in this case. --message , -m Replace the standard message shown to ask for password for the argument passed to the option. Only use this if --description does not suffice. --print-pass, -p Ask gksu to print the password to stdout, just like ssh-askpass. Useful to use in scripts with programs that accept receiving the password on stdin. --sudo-mode, -S Make GKSu use sudo instead of su, as if it had been run as "gksudo". --su-mode, -w Make GKSu use su, instead of using libgksu's default. pooky2483@pooky2483-ubuntu12:~$ apt-get -f install E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root? pooky2483@pooky2483-ubuntu12:~$ sudo apt-get -f install E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? pooky2483@pooky2483-ubuntu12:~$ gksu apt-get -f install gksu: invalid option -- 'f' GKsu version 2.0.2 Usage: gksu [-u ] [options] --debug, -d Print information on the screen that might be useful for diagnosing and/or solving problems. --user , -u Call as the specified user. --disable-grab, -g Disable the "locking" of the keyboard, mouse, and focus done by the program when asking for password. --prompt, -P Ask the user if they want to have their keyboard and mouse grabbed before doing so. --preserve-env, -k Preserve the current environments, does not set $HOME nor $PATH, for example. --login, -l Make this a login shell.
