In order to use an USB-Stick encrypted with Bitlocker I installed Dislocker on my Ubuntu 16.04 according to Use (Windows) BitLocker-encrypted drive on Ubuntu 14.04 LTS.
Unfortunately I cannot decrypt:
sudo fdisk -llists 4 Partitions even though there is only one partition on the USB-stick. And the size is wrong too. (The Disks Utility shows also only one partition.
sudo dislocker -r -V /dev/sdb4 -uMyPassword -- /media/bitlockerdoes not mount any of the 4 listed partitions
