[Bug 1205397] Re: encrypted install fails because unsafe swap (zram) is detected

[Joe]

Yes, I ran into this problem again when attempting a install of 14.10
using my (encrypted) 14.04 partitions.  Very frustrating since it takes
5+ minutes per iteration after you quit and try something different.
The problem seems worse -- I tried at least 5 or 6 different variations
before finally being able to complete the install.  Even though I would
run "sudo swapoff --all" (from the terminal, from a virtual console),
I'd still get the error.  I tried deleting my existing partitions and
creating new partitions.

The problem seems worse (or perhaps it's an additional problem) -- there
were several times that I was trying the approach from comment #11 and
not setting mount points until the end, but then the problem was that
after I created one physical volume for encryption, the installer would
hang when I created the second.  (One partition for swap, one for /, in
addition to the unencrypted /boot partition).

In the end, the solution I came up with was to create a partition for
swap but not to use it at all.  (I.e., an install with no swap).  Now
that the install completed, I'll go back and set up that partition to be
swap after the fact.  This will probably be better anyway -- I'll be
able to set it up so that it uses a random key for swap encryption so I
only need to type one passphrase to boot.  (Which is fine since I never
do a hibernate anyway.)
