I don't know why, It wasn't happening yesterday. Was it because I turned the machine off and back on again this morning?

Anyway here's the error. GkSudo won't run anything at all now.

(gksudo:3262): GLib-CRITICAL **: g_str_has_prefix: assertion `str != NULL' failed

This happens no matter what. Funny thing is, gkSudo comes up with the password box, I enter the root password, then the problem happens.

I want my gksudo back can anyone help? I cannot find documentation for this error at all. I don't know where to look, this is my second ever day using Linux.

I'm on Debian Gnome.

  • Are you sure you should enter the root password? Normally sudo asks you to enter your own password. Also, it might help if you specify the exact version of Debian you are on (see /etc/debian_version if you are uncertain) and any changes (package updates, configuration changes, etc.) that you have done recently. – a CVn Nov 16 '12 at 13:50
  • Is sudo working? – Karthik T Nov 19 '12 at 2:09

    This is the same question as this problem in ubuntu, and it's not a problem with sudo, the password entered, or anything else, it's a bug, reported both in ubuntu and debian. – anarcat Feb 6 '14 at 4:05
