Thanks for looking at this, Michael. I'm not on that machine, so I can't give you a copy of any logs.
I can tell you that the ghost window that pops on and off is debconf. The same problem occurs on another machine also installed with the same version of Xubuntu last week. So it is possible to recreate the problem. I hereby confirm my own error report. Are you trying to tell me that this error is not known? Surely it's common? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1085483 Title: Software Center password and install operation working sporadically To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1085483/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
