Re: Remove disk encryption in Maintenance Mode

Thank you for your suggestions.

Keyboard does not look like it is the issue.

I also tried to start the fedora rescue selection, but it also
required the entry of the LUKS passphrase (Curiously, while a normal
release starts with a different gui and stops asking for the passphrase
after 4 or 5 attempts, the rescue selection just keeps asking for the
passphrase ... maybe forever.)

So, I decided to see if I could get the DVD drive to be recognized by
the motherboard. When I put a DVD into it and executed from
Maintenance Mode:
cat /dev/sr0
nothing is produced.
The media server has been quietly sitting in a corner for years.
Anyway, with a twice over with my small air compressor making
sure I manually opened the DVD drive and clearing any dust, the
system then recognize a DVD and I could do an installation:
installed linuxmint-20.3-xfce-64bit.iso
then installed Fedora-Xfce-Live-x86_64-41-1.4.iso over the linuxmint
installation but kept the /boot/efi directory so that
the installation did an efi installation (not bios).
I assume this is a trick that is not known by many and as my
original email said, It was just chance that I guessed it might work.

While there was some stuff in the original /home directory, all of the media
was on other, non-encrypted drives which I've now been able to mount in
this new installation.
Thanks again.

Just to be thorough...  On the graphical login screen see if there's an
icon for choosing keyboard layout/language.  It is possible for the
command line (purely textual interface) to be different from the
graphical interface.

You can't remove disc encryption without re-writing every bit of data
stored on the disc.  When using an encrypted disc the system is
decrypting the data on the fly, it's always encrypted on the disc.

Are you sure you want to do that, or simply access the encrypted data?

Of course, when it comes to updating an old installation of something
with a new version of something else, there is every chance that the
old encryption scheme isn't supported any more, so you would have to
re-encrypt the drive (or just decrypt it, if you don't want encrypted
contents any more).

You should probably be booting from something else, and something
that's compatible with the original encryption scheme, to do this.  I
wouldn't risk trying anything that was going to decrypt in-place when
its running from itself, well not if the OS is encrypted.  I'd be more
confident about doing that if it's simply user data space that was
encrypted.
