My USB Drive is not mounted automatically but it has detected through lsusb.

I also used dconf-Editor but it is not working. Every time I have to mount manually through Disk Utility.

A complete description for configuring auto-mount is given here:

https://help.ubuntu.com/community/Mount/USB

If this does not help, please insert your usb-stick and post the last lines of dmesg and syslog.

Have you recently not unmounted the drive correctly, either power failure or a crash while writing to or reading from the drive? This can cause errors with the drive and while once mounted it functions normally the superblock may have errors causing it to not mount correctly.

As Requist asked, check dmesg immediately after inserting you flash drive, you may see one of the last lines as "Volume was not properly unmounted. Some data may be corrupt. Please run fsck.".

Check the device label in gparted then run

sudo fsck /dev/xxx (swapping xxx for your device)

You may get some details back about an invalid Superblock.

Fixing this is dependent on the drive filesystem, is it ext4 or Fat32 etc?

Here's a page on repairing an ext4 superblock

If your drive is fat32 or other msdos type, then testdisk may help but be careful with this tool, with great power... 

sudo apt-get install testdisk
sudo testdisk

here is a post on using testdisk to repair a fat32 superblock issue. It links to this post, read both before starting.

Hope it helps.

This is a bug described in Bug #1768010: usbmount does not work on Bionic. The solution, also given in Unix & Linux Stack Exchange, is the following:

Edit the systemd-udevd configutation

sudo systemctl edit systemd-udevd

insert the following two lines:

[Service]
MountFlags=shared

then run:

sudo systemctl daemon-reload
sudo service systemd-udevd --full-restart

Note also that this workaround is not perfect: a delay of 40 seconds can be observed between the time an usb key is inserted an the time the auto-mount is fully executed.

When all else fails, just mount it manually. Another alternative is upgrade to a recent version of Ubuntu. Both have worked for me in the past.

$ mkdir xxxxxxx
$ sudo mount /dev/sdb1  xxxxxxx
$ sudo umount xxxxxxx

or

$ pmount /dev/sdb1  xxxxxxx
$ pumount xxxxxxx

It's likely that the drive is not formatted properly.

You can use the "mkfs" utility to build a Linux filesystem on the device:

mkfs.vfat -F 32 -n NAME /dev/PARTITION

Replace name with the name that you want to assign your USB drive, and replace partition with the name of the partition on the device; which would be something like sdb1.

I had the same problem with my USB device not auto-mounting, and this resolved the issue for me.

This is working to me: System Settings > Hardware > Removable Storages > Removable Devices > give check the "Enable automatic mounting" > give checks the partitions you want to be automounted under the column "Automount on Login" > OK.

Opened Disks / GParted apps may result in not working USB automount at time of testing. Try to close these apps and then re-plug USB flash drive.
