I experienced this issue twice in the last 24 hours on 16.04. Both times, I waited over an hour after the computer froze before performing a hard reset on the machine. (The expected time for the operation to complete was under 10 minutes.) In my case, the computer goes directly from working as expected to being completely unresponsive, freezing all input (keyboard, mouse, power button) and output (screen, file transfer).
The bug does not appear consistently, though. After restarting the computer, performing the same file transfer worked without any issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1208993 Title: Ubuntu slows down and hangs while copying file from/to USB To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1208993/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
