"Environment validation failed for part 'xsv': 'cargo' not found" with `base: core22`
Metadata
Current evaluation
The core22 Rust plugin's false "cargo not found" failure is resolved: rustup support landed in Snapcraft #4297, followed by an explicit rust-deps validation fix in craft-parts 2.2.0.
Suggested action: close resolved
Reason: Snapcraft PR #4297 was merged as commit b357ef5e7, and the later craft-parts commit dc79714c (PR #903) explicitly improved Rust dependency validation. Craft-parts 2.2.0 and Snapcraft 8.6.0 document the rust-deps validation fix, and the current plugin handles rust-deps before validating cargo and rustc.

Launching instance...
Environment validation failed for part 'xsv': 'cargo' not found and part 'xsv' does not depend on a part named 'rust-deps' that would satisfy the dependency.
