I am trying to install flavor X over encrypted flavor Y, however, I am not able to decrypt my encrypted flavor Y partition before the installation process. I have used stock encryption of the Ubuntu installer (LUKS)
How can I decrypt my partition then install flavor X over Y ?
EDIT: I should mention that I also seek flavor X to be encrypted while keeping my personal files on my partition as well
rsync
the/home
directory to a directory or partition in an external drive). Install the new system. Finally copy those personal files into your new system. – sudodus Feb 18 '17 at 06:24
