    Re: Kernel reinstallation via chroot on encrypted sda5

    apt2; Sheesshh,

    I have been considering this, and see no way forward until the file system is UNlocked. Even to remake the keyfile one must have access to the file system.

    It is past my witching hour, and I am retiring for this session. Will have it on mind and take it back up in my AM.

    It can be hoped between now and then some others with the experience will chime in here and offer some guidance.

    take a break

    Thank you for all your help! I hope we can find a solution before my impatience succeeds me!

    In the AM, we shall look in to fstab and crypttab performing a luksopen in boot, and any ideas you can come up with!

    Hah, well, I put the nail in the coffin. My grave is complete. I have made a change I can't go back from.

    Can't even chroot in, /dev/sda5 is beyond repair. Everything is gone. I have come to terms with this and will be moving on to a new distro.

    Thank you all for your time you have invested, I hope we have all learned something from this venture.

    I shall go shed a tear for losing 8 months of work and hundreds of lines of code- but start fresh with a new distro, and more knowledge than before.

    Thanks again, Cheers!

    Understand that the entire purpose of encryption is to prevent anyone without passphase from seeing data. And you have to have really good backups for any data as drives & systems do fail. Almost all recovery tools require access to system and if encrypted then it is difficult or impossible as it should be.

    I do not use encryption, but did save a few links.

    It's just a shame you didn't mention right at the start that saving your data was the priority here - it looks like you successfully decrypted the LUKS container and mounted the mint filesystem from the live CD back in your very first post.

    There really was no need to be messing around with chrooting and repairing the boot - you could just have copied all of your documents off to external media at that point.
