Encountered an unknown error when doing 'sudo tap update'

The system is Debian Sid on amd64

I tried re-installing tap with no luck.

Could you send over the contents of /var/cache/tap/mpr-cache.json? I'm suspecting this is an issue from something on the MPR itself (though Tap should also be handling it correctly when the situation arises).

/var/cache/tap/mpr-cache.json just has 2 lines with an open bracket on one and close bracket on the other. No data in there.

I installed makedeb from the apt repo and then installed tap with makedeb.

That adds up, that's the error I was seeing in the MPR.

I think the issue is that Tap finds all packages that are marked as MPR packages, but if the packages can't be found in the MPR cache (such as is the case here with the bracket scenario), the error you got above occurs.

I'll see if I can get that fixed shortly.

Awesome. Thank you! :)

Hi, I just tried tap again and it works now! So I guess whichever changes were made in the last few hours have fixed it.

That's my bad, I should've posted that I added the fix in the MPR :o

I'm gonna keep the issue open for the time being though, because the underlying issue still needs to be fixed.

Alright. I'm just happy that it works now for me :)
