Ubuntu: Mount Bitlocker-Encrypted partition

Install dislocker
sudo apt install dislocker
Create folders for mounting
sudo mkdir /mnt/bitlocker
sudo mkdir /mnt/bitlockervol
Decrypt drive
sudo dislocker /dev/sda1 -u password -- /mnt/bitlocker

#replace /dev/sda1 with the volume you wish to decrypt
Mount partition
sudo mount -u loop /mnt/bitlocker /mnt/bitlockervol/dislocker-file
Mount NTFS if above command is not working
sudo mount -t ntfs-3g -o loop /mnt/bitlocker/dislocker-file /mnt/bitlockervol
Mount automatically using /etc/fstab
sudo nano /etc/fstab

#add the following two lines
/dev/sda1 /mnt/bitlocker fuse.dislocker user-password=password,nofail 0 0
/mnt/bitlocker/dislocker-file /mnt/bitlockervol auto nofail 0 0

Instead of using your user-password you can also use the recovery-password by using the parameter recovery-password instead.
