Cannot mount USB Stick on Ubuntu 22.04:

Question

On Ubuntu 22.04, when I try to mount my USB Stick on my file explorer (right-click on it in the side bar, then 'Mount'). A window appears with "Failed to mount USB Stick, an operation is already pending". I can't figure out what is this operation. This behavior is new. The file system on the stick is ext4.

Thank you for your help

EDIT: I still have not found a solution for this. With GParted, I can see that the data are still there on the stick, but when I try to mount it to a directory, it keeps trying forever, without finding anything.

I suggest that you create the mount point

sudo mkdir /mnt/usbdata

and find the UUID with lsblk

lsblk -e7 -o name,fstype,uuid

and edit your file /etc/fstab according to the advice in the manual page

man fstab

and add the following line (use your own file system's UUID):

UUID=4c518694-d97c-4910-bb7b-eeb6a6b73874  /mnt/usbdata  ext4  noatime 0  0

If you do not always keep the drive (USB stick with the ext4 file system) connected, you should add the boot option noauto (so noatime,noauto in field #4).

With the noauto option, you should mount the drive by the following command in a terminal window,
