I managed to work around this bug by adding user accounts to the "root" group in /etc/group.
Yes, I do know this is a nasty, odiferous kludge, with so many horrible security implications that I can't even count them, but my elderly mom (who really doesn't understand the difference between Windows and Linux and only knows that she hasn't been able to use her camera on her computer) would probably have gone out and bought a new camera AND a new computer some day if I hadn't found some sort of fix (or messy pseudo- fix) for this problem NOW. Presumably, the right way to fix the problem would be to change the permissions on the usbdev* special file created in /dev when a camera is connected. -- Error initializing camera: -60: Could not lock the device https://bugs.launchpad.net/bugs/331681 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
