Computer one: OS: Ubuntu 18.04, Username: userone. Computer two: OS: Lubuntu 18.10, Username: usertwo.
I am having problems with a LUKS encrypted USB stick.
The USB stick was created on computer one and I have no problems using the USB stick on this computer. When I take the USB stick to computer two and type in the same passphrase I use on computer one to decrypt the USB stick, computer two gives the following error message:
Error unlocking /dev/sdd1: Failed to activate device: Operation not permitted
Any idea why?
