Don't know if this helps anyone else, but I was able to resolve this by starting gparted and exiting. Based on some other bug reports, gparted prevents automounts while it is running: https://bugs.launchpad.net/ubuntu/+source/gparted/+bug/134712
Although the exact case in the old bug didn't apply to me, I just ran gparted and closed it and now things are automounting. -- USB Thumb Drive can't mount anymore in Hardy https://bugs.launchpad.net/bugs/211760 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
