My previous Manjaro system broke down when the computer accidentally turned off during an update. Apparently, kernel files were damaged and now I can' t boot into my previous system. I tried a couple of things to fix it but there was no success, so I decided to do a fresh install. After all, my files were stored in a separate partition (mounted as
/home in my previous installation) so didn' t have to worry about losing anything important and the reinstall should be easy. I wanted to do it from live USB using Manjaro Architect. In the beginning, I thought I would just explore the options in the Architect so I navigated through the installation preparation menus and researched what each option means. While doing this, I also explored the LUKS Encryption menu where I selected the automatic option and my data partition which would make sense to encrypt. I got to the point where Architect prompts for passphrase for the encryption but I did not enter a passphrase and selected
cancel to go back as I was not yet ready to proceed with the actual installation. I closed the Architect as I wanted to do some other stuff in the live USB before proceeding and then I noticed that I can no longer access my data partition which now shows up as an encrypted drive and asks for a passphrase. Obviously, I don't know the passphrase since I did not choose one. Leaving the passphrase field empty also does not work. I was able to access files in this partition from the live USB before so I am sure that the problem was most likely caused when I navigated through Architect. Also, I had not used any encryption in this computer before.
Is there anything that can be done in such a situation to gain access to the partition? I know that there are no solutions to forgotten passphrases but this situation is quite different since LUKS seems to have performed encryption without me asking for it.
Even if my files are lost, perhaps this is something that can be addressed in future releases to prevent similar situations.
