Protondrive: Invalid signature caused by openpgp: signature made by unknown entity

[tcrasset]

What is the problem you are having with rclone?

First of all, thanks to the rclone developers and @henrybear327 for the much awaited proton integration.

I'm having issues downloading some files from my drive. Some files it works, some files it doesn't and show me a

Invalid signature cause by openpgp: signature made by unknown entity error.

I looked through #6072 as there was a similar issue going around, but it was hard to follow the whole discussion. At the time, there was a config option skipSignatureVerification that seemed to have been removed.

I figured creating a new issue specific to that problem might help centralize the discussion rather than cluttering up the one mentioned above.

FYI, the file I'm trying to download is dated January 12, 2022. It seemed from the discussion that older files were more likely to have signature issues.

Appreciate any help, feel free to ask for more information, I can also lend a hand too @henrybear327, not familiar with Go though (that can change).

Hello @tcrasset,

Thanks for reporting!

Yes, indeed, I removed the special config flag since that's just a temporary hack.

I will make a custom build for you so I can see what part of the verification failed (I think I actually need to make this a debugging feature so it would be easier to see exactly what field is failing, e.g. name, node, etc..)
