[Bug 1759732] Re: [Lubuntu] Having zram support means that encrypted LVM installs don't work

skip the checks for it.

I remember briefly looking into this and seeing a conditional with one
exception in there so far, so adding this might be trivial. That's
probably the solution here.

> Is zram still in use, in the installed systems too?

No, just on the live system.

> Does it affect encryption at rest? (e.g. does zram memory remain
unencrypted upon hybernate?)

No, because it isn't in the default install (and the live image is not
encrypted).

Title:
  [Lubuntu] Having zram support means that encrypted LVM installs don't
  work

Status in partman-auto-crypto package in Ubuntu:
  Confirmed
Status in partman-auto-crypto source package in Bionic:
  Confirmed

Bug description:
  Lubuntu enables zram support on our live images. Currently, zram is
  caught by the unsafe swap detection performed by this package (or
  similar). This is causing Encrypted LVM installs to fail. Unmounting
  all zram mount points result in a successful install.
