Thanks so much for posting the log file. From this I can see that indeed the backend is not launching as it should:
2013-05-29 12:53:10,091 DEBUG Sending message with sequence number 0 to backend 2013-05-29 12:54:10,152 DEBUG Backend didn't respond, trying to create again. 2013-05-29 12:54:10,153 DEBUG Sending message with sequence number 1 to backend 2013-05-29 12:55:10,214 DEBUG Backend didn't respond, trying to create again. 2013-05-29 12:55:10,215 DEBUG Sending message with sequence number 2 to backend The failures to create the backend mean that it didn't start, this is usually caused by the privileged runner (sudo, gksudo, etc) not launching the backend, usually due to a bad password (but in your case we know you're entering the correct password, so the problem lies elsewhere). OK so let's try replicating Checkbox's backend launch process. Could you run these commands on a terminal and let me know what happens? Also, if any of these pop a graphical window, I'd really appreciate if you could take a screenshot of some sort. kdesudo ls gksudo ls sudo ls My expectations are: kdesudo ls - This should say that kdesudo is not installed (which is correct). gksudo ls - On an stock Ubuntu system, this should say that gksudo is not installed. But in your case I suspect it will pop up a window asking for the password. Enter your user's password (not root's). I suspect it will say the password is incorrect and ask you again. sudo ls - This should ask for the password on the console, and work correctly by showing a directory listing. If this holds, it would mean that somehow gksudo got installed on your system, and it's not correctly recognizing your password, possibly due to the keyboard layout problem you mention. But let's cross that bridge when we get to it. Thanks for your help chasing this problem down, I know it's been a slow process but we have some good clues now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1184061 Title: checkbox does not accept my valid (for everything else) password To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/checkbox/+bug/1184061/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
