ownCloud/onlyoffice install: Signature data not found

[sorabjinyc]

I had no problem installing version 10.0.10.4 on a Centos 7 dedicated server using Softaculous. When I try to install Onlyoffice using the Market it appears to install successfully, but there is no way to access it. An integrity check message says “Signature data not found”. Is there an easy fix for this? I see this same issue was posted in 2017 but that earlier thread does not seem to solve my problem.

Raw output

Array
(
    [onlyoffice] => Array
    (
        [EXCEPTION] => Array
        (
            [class] => OC\IntegrityCheck\Exceptions\MissingSignatureException
            [message] => Signature data not found.
         )
    )
)

The documentation says that you do not have a signature file.
But the market has a signed app.

Could you please specify if the problem recurs or we can close the topic?
