Astra CLI on Linux via Homebrew fails with "exec format error: astra"
Complete solution
How to fix: Astra CLI on Linux via Homebrew fails with "exec format error: astra". The homebrew tap originally shipped only the macOS binary, so on Linux you got exec format error. The maintainer fixed the formula in 0.2.1 to install a portable Java-based build on Linux instead: run brew upgrade datastax/astra-cli/astra-cli to pick up the fixed version.
The problem
On Linux (Ubuntu 20.04), installing the Astra CLI with brew install datastax/astra-cli/astra-cli and running astra setup failed with: exec format error: astra. The homebrew formula was only set up to download the macOS binary, so Linux got a Mach-O executable it could not run.
