I previously encrypted the contents of a USB drive using the top answer from this Ask Ubuntu question:
https://askubuntu.com/questions/6359...m-command-line.
The USB drive worked fine until my computer recently froze and was restarted. Now the contents of the USB drive seem inaccessible, which is the problem I would like to solve. The following line no longer prompts for a decryption password, doesn’t appear to do anything, and simply goes to the next terminal line:
Code:
(xenial)username@localhost:~$ sudo cryptsetup luksOpen /dev/sda securebackup
After the above luksOpen line is used, attempting to mount the securebackup yields the following:
Code:
(xenial)username@localhost:~$ sudo mount /dev/mapper/securebackup /media/removable/USBDevice
mount: special device /dev/mapper/securebackup does not exist
How can the contents of my USB drive be accessed again?
