No error shows up.

Diagnostic Logs

• Report on Launchpad: LP#1966849
• Possibly related: gzip from Ubuntu Eoan doesn't execute #4461.

Similar to that one, the same binary runs perfectly OK on a native Ubuntu Jammy machine. However, this time the binary is 97520 bytes and no section points outside this range.

The previous version gzip 1.10-4ubuntu1 is fine, so I've installed that one instead and setting apt-mark hold for now.

It's very interesting that only gzip is found problematic. And it's the same program as 3 years ago. Time to wonder if gzip has any magic to break on WSL1.
