[Bug 1943833] Re: fwupd failed to update metadata for lvfs

[Yuan-Chen Cheng]

Hi Mario, Could you share the command to verify?

A quick cross-check, the file in ~/cache/fwupd/remotes.d/lvfs is the
same if I compare the one downloaded by plasma-discover and "fwupdmgr
refresh"

One more thing, it looks like the backends/FwupdBackend/FwupdBackend.cpp
has been through lots of re-factoring. Mind have a look at the source
code for the one used in focal.

One thing I can see is: new code just use
fwupd_client_get_remotes_async, while old code seems download file and
call fwupd_client_update_metadata.

Bug description:
  When running `fwupdmgr refresh` from the command line or when
  performing an update from the Software application the following error
  will be thrown:

  Failed to update metadata for lvfs: checksum failure: failed to verify
  data, expected 98261db7124c8026fb88f77768787efc2f8355c3

  The cause is an outdated libjcat, as explained in the upstream bug
  report:
  https://github.com/fwupd/fwupd/issues/3652#issuecomment-912677175

  0.1.3 is included in Ubuntu but at least 0.1.4 of libjcat is required
  to function properly.

  Firmware can not be updated any longer as a result unless forcing the
  update manually by performing `fwupdmgr refresh --force`.

  This means the libjcat dependency of this package needs to be set to
  0.1.4 minimum and the libjcat package itself needs to be updated.
