I need to get into an encrypted Ubuntu system (14 maybe?). And, yes, it is mine, I am the legal owner, etc. Problem is, I lost the passphrase in a move. There is some data in there that is pretty important to me.
I uploaded some images -- these are as far as I am able to get: https://i.stack.imgur.com/35h4Q.jpg .
It is the sole OS on an Acer laptop.
How can I bypass the encryption without losing the data? Surely this is possible. Please, check out the link to the images to get a better idea of the various methods I've attempted.
Update: Most people seem to suggest it is impossible but for brute-force. I would suggest that the version of Ubuntu is at least 2 years old. Might there be outdated security glitches?
