This is really a gksu or sudo bug. My system is up to date. If i put in a terminal gksu any_comand_here, nothing happens. If i try the su mode (with -w), they asks for the password of root.
This is the output for gksu -d gedit :~$ gksu -d gedit No ask_pass set, using default! xauth: /tmp/libgksu-MnZ9Qv/.Xauthority STARTUP_ID: gksu/gedit/5920-0-acerola_TIME612798 cmd[0]: /usr/bin/sudo cmd[1]: -H cmd[2]: -S cmd[3]: -p cmd[4]: GNOME_SUDO_PASS cmd[5]: -u cmd[6]: root cmd[7]: -- cmd[8]: gedit buffer: -- buffer: -- buffer: -- *********** (the line above repeated a lot of times)********* brute force GNOME_SUDO_PASS ended... No password prompt found; we'll assume we don't need a password. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ If i try :~$ sudo -H -S -p some_password_here -u root -- gedit the answer is: some_password_here and the process continue until i press ctrl+c, the the message above apears: sudo: pam_authenticate: Conversation error -- update manager stops when update check is asked manually https://bugs.launchpad.net/bugs/224303 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
