I booted another machine (currently running 18.04) from the USB memory stick with 16.04 on it. I plugged in three USB memory sticks. Each came up in a couple of seconds. When that machine is running 18.04 it takes 4+ minutes for a single memory stick to be available.
Note that dmesg shows that the OS sees the memory stick nearly immediately. It's Nautilus (guessing) that doesn't make it available. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1773597 Title: USB flash drive won't mount To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1773597/+subscriptions -- desktop-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
