Using 'passphrase' with GPG doesn't work (promt opens)

[Roko131]

  encrypt_with GPG do |encryption|
    encryption.keys = {}
    encryption.passphrase = 'secret passphrase'
    # encryption.mode = :both
    encryption.mode = :symmetric
  end

But running backup perform --trigger my_backup prompt passphrase windown, not using secret passphrase.

Why?

Because as of version 2 of GPG, the option --batch is needed to ensure no prompt. as can be read in the manual.

If this command is used with --batch, --pinentry-mode has been set to loopback, and one of the passphrase options (--passphrase,
--passphrase-fd, or passphrase-file) is used, the supplied passphrase is used for the new key and the agent does not ask for it. To
create a key without any protection --passphrase '' may be used.

How I fixed it:

just added the --batch flag:
In lib/backup/encryptor/gpg.rb, symmetric_options method:
changed
"-c --passphrase-file '#{path}'"
to
"-c --batch --passphrase-file '#{path}'"

My gpg version: gpg (GnuPG) 2.2.12
