I'm a very long time Ubuntu user (over a decade) but have not been here as I've had no issues with Ubuntu. With the arrival of Ubuntu 20.04 LTS I decided to encrypt my data (or system if needed). I'm looking for the following:
- Method to reinstall ubuntu with LUKS encryption on a previous LUKS encrypted Ubuntu install on a dual boot system with Windows 10.
- Keep all my personal files (ie
/home
folder) intact, with or without a separate partition. I do not wish to move everything out, reinstall and then move stuff back in. - Simple GUI based approach through the standard installer. I know how to use the command line but I'd rather not, especially for something as sensitive as encryption.
What I'm looking for is basically the same as this document. Except that I need it on an LUKS encrypted system/partition. I tried doing this on a spare system with Ubuntu 20.04, and I could not find a way of telling the installer the passphrase to the encrypted system. The end result was a reinstall that wouldn't boot or the encrypted partition gets wiped out. I also tried to run installer with and without pre-unlocking the encrypted partition but to no avail.
I am able to do all of the above with Fedora, OpenSUSE, Manjaro, (although they only do this when /home
is on separate partition, which is fine for me) so I'm not sure what I'm doing wrong in Ubuntu.

Based on the my personal experiments using the Ubuntu 20.04 installer, online research, and asking various forums (and lack of answers there), I conclude that as of today, there is no way to do all of the following:
/home
partition or not) without destroying pre-existing personal files...Of course there are ways of doing this if you rely on the command line, which I was looking to avoid. I've decided to switch to Fedora 32 as it meets all these requirements. Ubuntu served me rather well for over a decade, hope to return when the above issue is fixed.
For those interested in my Fedora 32 setup:
/boot/efi
partition from Windows 10 install/boot
partition/
partition/home
partitionThats the summary, its been a week and so far things have been great with Fedora 32. I've not really noticed much difference from Ubuntu for my needs (Email, Browsing, viewing photos/videos, music, skype, spreadsheets, documents).
Thanks!
