[JFconcept]

same for me, no solution yet

[fugazidave]

I'm experiencing exactly the same problem.

[asha23]

Broken for me also.

MacOS 10.14.6

[OffCorner]

ended up using https://traktor.wp-migration.com/
seems to work fine

• Same for me on macOS 11.6.
• It decompresses a few folders and files (ca. 3 MB of the 90 MB archive) but then fails.
• Note: My stacktrace also contains the absolute user path:
  /Users/abdullahirfan/go/src/github.com/yani-/wpress/reader.go
• And I'm definitely not Abdulla Firfan.
• This seems to be the full name of the maintainer alias fifthsegment .

@fifthsegment

• Maybe your app contains some hardcoded filepaths so that this app only works on your computer?
• My stacktrace is a bit different in nature. I post it here, maybe it helps:
