lubuntu 13.10 installation (encrypted home, no swap) fails

[axel]

steps to reproduce:
0) prerequisites (probably do not matter?): pre-format disk to 3 partitions: boot (~200mb, ext2), system (~20gb, ext4), home (~80gb, ext4); all partitions empty and unused.
1) start lubuntu 13.10 (64bit) installation.
2) choose encrypted home 'who are you' user-setup dialogue.
3) click 'continue'.
4) notification window pops up (title 'ubi-usersetp crashed'): ubi-usersetup failed with exit code 1. further information may be found in /var/log/syslog. do you want to try running this step again before continuing? if you do not, your intallation may fail entirely or may be broken.
5) chosing 'try again' would fail again
6) chosing 'continue anyway' would lead to a stuck installation process

Expected behaviour:
installation continues and succeeds

/var/log/syslog reads:
WARNING: there were no usable swap devices to be encrypted. exiting.

when adding a (even very small) swap partition the installation succeeds.
as my system features enough ram for my needs plus an ssd which i would not want to wear unnecessarily i was hoping to be able to install lubuntu (fed up with unity and gnome3 -> lxde) without being forced into any certain partition scheme.

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

[step21 (step21)]

 The bug also occurs when asking for an encrypted LVM install or when asking for an install onto a LUKS partition.
The bug is still active with Lubuntu 14.04 (final version)

This release of Ubuntu is no longer receiving maintenance updates. If this is still an issue on a maintained version of Ubuntu please let us know.

[axel (x.)]

Thanks for your feedback, i've been waiting for something for over 5 years in this matter.

To be honest, I can't tell if this is still an issue on a maintained version of Ubuntu because in the meantime I've turned my focus away from Ubuntu, one reason being that bug reports are ignored for extended amounts of time.

So yeah, let this bug expire...

[Marcus Tomlinson (marcustomlinson)]

I'm so sorry that your issue has gone unnoticed for this long :( The backlog we've accrued here is truly unfortunate. We would really like to see the situation improve, but with over 2000 open bugs, manually testing each is honestly almost impossible. The aim today was to ping these old bugs and allow anyone still effected to respond and put their bug onto the radar again.

[Expired for ubiquity (Ubuntu) because there has been no activity for 60 days.]
