Persistance or installing


I am running parrot 4.2 on a usb stick.

2 options I need help with:

preferred help: When trying to install with parrot installer or parrot installer gtk onto a 1 tb external HDD the installation dies at 17% and says installation failed at this step: Install System.

or this: I want to add persisance but to save the persistance to another drive as my usb stick is anly a 15gb.

place your 2nd usb drive into your computer bring up a terminal type sudo fdisk -l
get the name of your drive you want the persistence to be on /dev/sda

:: For an encrypted partition use the following commands ::

cryptsetup --verbose --verify-passphrase luksFormat /dev/sdb
cryptsetup luksOpen /dev/sdb my_usb
mkfs.ext4 -L persistence /dev/mapper/my_usb
e2label /dev/mapper/my_usb persistence
mkdir -p /mnt/my_usb
mount /dev/mapper/my_usb /mnt/my_usb
echo “/ union” > /mnt/my_usb/persistence.conf
umount /dev/mapper/my_usb
cryptsetup luksClose /dev/mapper/my_usb
reboot and your 2nd usb drive should be encrypted

See my comments in this thread for encrypted persistence issues:
Live USB with Persistence

I recommend creating two partitions on your encrypted persistence stick; one for your OS settings, and one for your personal files.
