Bug#1088279: cdimage.debian.org: Unable to assign 'mount point' in net-install for encrypted mapped devices

[Cyril Brulebois]

Control: severity -1 normal

Hi,

Package: cdimage.debian.org
Severity: grave
Tags: d-i
Justification: renders package unusable
Dear Maintainer,
* What led up to the situation?
Trying to install Debian 12
* What exactly did you do (or not do) that was effective (or
ineffective)?
net-installer refuses to give the option to offer a "use as: ..." during installation.
* What was the outcome of this action?
Not able to install.
* What outcome did you expect instead?
Assigment of mount point.

Please describe the exact steps you're following.

Please take a look at https://forums.debian.net/viewtopic.php?t=161054

Please include all relevant in the actual bug report.

As explained, the net-installer seems to have a bug not offering an option to set a mount point.
The code used in the DVD-installer works as expected.

I'm not exactly sure the code is different



Cheers,

Steps to reproduce in net-installer, more or less quoted from
https://www.reddit.com/r/debian/comments/146vw37/guide_install_debian_with_encrypted_root_and/

Installer menu Partitioning
1 Select "Manual Partitioning"
2 Select the free space/partition and choose "create partition."
3 Use As: Physical Volume for Encryption
4 Scroll up to "configure encrypted volumes" > write changes, then
"create encrypted volumes."
5 Select "partition" > "finish"
6 Create your encryption password
7 Partition disks....
8 Scroll to "encrypted volume" and select the partition listed beneath
to edit it.
9 Set mount point to "/" (root) > done setting up partition
10 Finish partitioning and write changes to disk

Typically net-installer does not offer step 8 while DVD-installer does.
In other words, "encrypted volume" is simply not visible.

As a consequence it is impossible to do step 9: select the volume and
assign a mount point.

Summarized, installing Debian using the net-installer on an encrypted
root partition is impossible.

Best regards, Wiebe

I've just tried that with debian-12.8.0-amd64-netinst.iso (and its 12.7
counterpart to be on the safe side) and I'm seeing the encrypted volume
just fine with both of them.

First entry is sda1_crypt, Linux device-mapper (crypt)
partition #1 is ext4, not assigned to a mountpoint initially

Second entry is sda, ATA QEMU HARDDISK
partition #1 is encrypted (sda1_crypt)

Strong disagree. Even more so given we provide guided partitioning with
encrypted LVM, which also works.

I just repeated the steps and it turns out that I was wrong here.

That said I feel really sorry for bothering you with this. On the other
hand, it took me much trouble to find some information on the net, to
find some logic in the order of partition steps and it is my believe
some improvement could be helpful, the Debian installation guide is
quite cheesy on the subject.

Again sorry and best regards, c'est la vie, Wiebe
