build is 'passing' but binary fails: exec format error

[bcdady]

Describe the bug
Following the steps from Installation - OSX and then running ketall results in the following error message: exec format error: ketall

To Reproduce
Steps to reproduce the behavior:

1. curl -Lo ketall.gz https://github.com/corneliusweig/ketall/releases/download/v1.3.6/ketall-amd64-darwin.tar.gz
2. gunzip ketall.gz
3. chmod +x ketall
4. mv ketall $GOPATH/bin/
5. 4. See error

Expected behavior
ketall should function as designed, such as demonstrated here: Demo

Desktop (please complete the following information):

• output of ketall version --full: n/a
• OS: macOS 11.1
• shell: zsh 5.8 (x86_64-apple-darwin20.0)

Additional context
I confirmed the same symptoms with v1.3.5 and v1.3.4. I even tried to make/build locally, and still got the same error

Sorry this does not work. I believe this might have something to do with upx/upx#222.
Have you tried if a build without upx compression works for you?

I can confirm there's an issue with the UPX-compressed binary at https://github.com/corneliusweig/ketall/releases/download/v1.3.6/ketall-amd64-darwin.tar.gz

Big Sur 11.1 (Intel)
ketall installed via krew (itself installed via Homebrew)
Any invocation (standalone or via kubectl) immediately results in Killed: 9

After Googling for similar issues it seemed UPX could be the culprit.
Installed UPX 3.96, uncompressed ketall with upx -d ~/.krew/store/get-all/v1.3.6/get-all-amd64-darwin: it works
Recompressed with this UPX version upx -9 ~/.krew/store/get-all/v1.3.6/get-all-amd64-darwin: still working.

Thanks @renaudguerin I had the same issue and I was also wondering.

Had the same setup than you and was able to fix it with the upx command you provided.

Thank you very much!
