Hi again Walter and all Lubuntu users,

I tested the Lubuntu Vivid beta 1 *desktop* ISO file corresponding to
the testcase with LVM encrypted disk and encrypted home. It is also
reported in the qa-tracker.

The computer is an hp Probook 6450b laptop with Intel i5 cpu:

http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c02218879

Trying to use the whole drive with encrypted LVM and encrypted home, It
complained about existing swap (which is zram), so I had to turn it off with

sudo swapoff -a

and restart Ubiquity. It complained that partman failed:

ubi-partman failed with exit code 141. Further information may be found
in /var/log/syslog. Do you want to try ...

The installled system worked, but I had the same error as with the
alternate iso file: there is no swap.

I wiped the drive (wrote zeros to the first megabyte using mkusb (dd))
and made an MSDOS partition table using gparted.

Then I tried again with Ubiquity, and succeeded: The installed system
works, and there is swap. See the attached file :-)

-o-

This method might work also in the alternate iso (if you also swap off,
wipe [the first megabyte of] the internal drive and create a new
partition table).

Best regards
Nio
