All files "tampered"

New install (yes, for those of you following along, I’m using php 5.6 this time) of FreePBX 14.

All signatures show as invalid and when I do fwconsole ma refreshsignatures it starts off with this:

Getting Data from Online Server...
Checking Signatures of Modules...
Checking builtin...
Signature Invalid
	Could not find signed module on remote server!```

After that it goes through and proceeds to apparently refresh all the modules, but I am still left with all my modules showing "tampered."

My OS was missing the dependency “dirmngr” which is part of GPG.

apt-get install dirmngr then fwconsole ma refreshsignatures and fwconsole reload solved it.
