I was just curious if anyone had heard anything or would hazard to take a guess. In Ubuntu 24.04 and Ubuntu 25.04 there is no option for encryption in the manual installation. I thought that maybe that was because the Ubuntu 24.04 installer is new and they just didn’t get around to it.
Just to clarify I’m not asking about other methods to get there. I’m aware of a few.
I believe that there has never been an encryption option for a manual installation. Please do correct me if I’m wrong.
There was some chatter some time ago, but I don’t know if anything has come of it. To do a manual installation, you’d have to pre-encrypt the drives. I haven’t tried doing this for some time, so I don’t know if it would work now.
You can encrypt a single partition via Luks on 22.04. I’ve done it. There was a drop down menu with the option of encryption.
Also if you already have an encrypted partition (as I do on Debian) if you open it via
sudo cryptsetup open /dev/sdX sdX_crypt
then the 22.04 installer will see the opened partition and you can install Ubuntu onto it. But in 24.04 the installer will not even see the opened partition so there’s no creating the encrypted partition via command line, opening it, and installing to it.
Anyway, thanks for the response paddy!
I wonder if there’s an open bug report for this? I know that there used to be one, but I don’t know whether or not it was closed. I couldn’t find it on Launchpad.
I found this bug report on Kubuntu and the Calamares installer.
Is it appropriate for me to file a bug report being as I’m not on Ubuntu? The 24.04 installer’s name is Subiquity right? I don’t think I want to install Ubuntu just for this. I would do the “online” bug report, I think.
(I can never quite decide between Debian and Ubuntu. But I prefer doing fresh installs to upgrade so this issue is in the con column of pros and cons. Incidentally, the Discourse is in the pro column. 
)
A recent post on UD led me to this bug report about encrypted lvm. Same kind of thing I think.
This has been around for a while (since 23.04) and nothing’s happened. Seems pointless at this point to add my voice to it. Also, I’m not doing the LVM part.
MAFoElffen, a poster on Ubuntu Forums, replied a couple of times to this bug.
Lubuntu, Kubuntu & Ubuntu Unity used the calamares installer for 24.04.
Ubuntu 24.04 LTS Server uses the subiquity installer.
Ubuntu 24.04 LTS Desktop uses ubuntu-desktop-installer, which does use the subiquity installer as its backend; but the user-facing installer is ubuntu-desktop-installer.
I see mention mostly of release, not which 24.04 product you were using (Server? Desktop? flavor like Kubuntu etc…)
Thanks.
Straight up Ubuntu Desktop (Gnome).
I should point out that MAFoElffen, in the bug report in post #6, said that “Unlike the subiquity installer, the new installer’s partitioner is not LVM, LUKS, BTRFS, nor ZFS aware.” So my question about encryption is really just a small part of the problem.
I guess, the same for Ubuntu Desktop 25.04. True?
I might have seen subiquity after switching to (working) console views of installation. Wasn’t really paying attention at the time … sorry.
TIA
Yep.
Installers used can vary on release; but 24.04 thru 25.04 are identical for all Ubuntu and flavors.
(eg. Kubuntu 23.10 used the ubiquity installer with a KDE-Qt skin on it; Lubuntu however still used calamares…; a lot of flavors switched to ubuntu-desktop-installer at 24.04, with only one flavor (plus Ubuntu Desktop which switched to it at 23.04) using ubuntu-desktop-installer at 23.10)
Found a couple of bug reports that more directly apply to my situation. Thanks to @Dennis_N for relaying the first one, which is authored by MAFoElffen . I voted for both.
Thank you for the bug links. I’ve voted for them.
Here’s another that, as far as I can tell, is about the same issue (albeit not specifically encryption):
This thread is relevant.
Thanks. I went ahead and voted for it.
And the thread you listed is where I got the first of my bug reports.
