Title:
  fwupd daemon failed verifying firmware signature

Status in OEM Priority Project:
  New
Status in fwupd package in Ubuntu:
  New
Status in libjcat package in Ubuntu:
  New

Bug description:
  The firmware blobs in cabinet archive are presently LVFS signed with
  gpg and pkcs7, if libjcat at compilation time without one then the
  blobs signed with both can't be verified.

  Impact is fwupd daemon will fail the firmware install immediately
  because OnlyTrusted=true is defaulted (in fwupd 1.7.x) to verifying
  the signature for daemon.

  We need uprev libjcat at least 0.1.4 onward to fix this issue.

  Issue is reproducible with fwupd 1.7.4
  -> https://launchpad.net/~ycheng-twn/+archive/ubuntu/fwupd174

  $ fwupdmgr --version
  client version:	1.7.4
  compile-time dependency versions
   gusb:	0.3.4

  daemon version: 1.7.4

  $ dpkg -l | grep libjcat
  ii  libjcat1:amd64    0.1.3-2   amd64   JSON catalog library
