@YuriGal let me know what OS you are on, I can provide a test build.

[YuriGal]

I run it in AWS CodeBuild, Linux.

[ekristen]

Builds are too big to upload here, finding another solution for providing intermediate builds.

[ekristen]

@YuriGal can you access this link? It contains all the binaries but the linux/amd64 is there -- should be able to test https://github.com/ekristen/aws-nuke/actions/runs/8196507179/artifacts/1307766418

[YuriGal]

Should be able to, need to reconfigure my setup a bit, but should be able to.

[YuriGal]

Sorry having issues doing it from CI environment, could you publish it as pre-release, so I can get it the regular way?
