crash when reinstalling broken lubuntu install - encrypted home on separate partition

[Xvani]

Previous install was a 15.04 that upgraded to 15.10, but failed and now I get black screen on boot.

crash occured when reinstalling broken lubuntu 15.10 install - encrypted home on separate partition.

Status changed to 'Confirmed' because the bug affects multiple users.

Although perhaps not a "duplicate" of Bug #1523194 that I reported, the two bugs at least seems related.

Have you tried installing only into boot (/boot) and root (/), and then moving home to a separate auto-mountable encrypted partition after installation has completed? (To get this to work, you'll also need to skip creating a swap partition during installation, and then create a swap partition, or a swap file, once installation has completed.)

This bug may also be related to Bug #1531387.

You appear to be trying to upgrade an existing installation that is broken. You will need to repair the existing installation, or do a clean install instead of an upgrade.

[GizmoChicken (gizmochicken)]

The existing installation isn't broken. Rather, it is also not possible to install /home into separate LUKS encrypted volume during upgrade OR during a clean install. I've tried with Ubuntu 15.10 and 16.04, Lubuntu 15.10, and Kubuntu 15.10. Please see Bug #1523194 for my report regarding Ubuntu.

Bug #1066480 could be related.

[Phillip Susi (psusi)]

They are separate issues and this one is still invalid for the reason mentioned before. Even if they are the same, we don't need two bug reports on the same thing.

[GizmoChicken (gizmochicken)]

Phillip,

I don't mean to speak for the original reporter of this bug. But my guess is that his mention of reinstalling a "broken" installation is a bit of a distracting.

As I reported in Bug #1523194, even during a clean install, I am unable to install /home into separate LUKS encrypted volume. Moreover, I have noticed that I am unable to upgrade from a working (non-broken) installation of Ubuntu 15.04 in which /home has been previously installed into separate LUKS encrypted volume, which bug sounds an awful lot like the bug reported here.

A you suggest, if they are the same, we don't need two bug reports on the same thing.

Although this bug was reported first, given that original reporter of this bug hasn't commented since his first post, I marked this bug as a duplicate of Bug #1523194, which I hope will remain active until a fix is released.

Best regards,
GizmoChicken
