[Pkg-rust-maintainers] Bug#1095961: rust-dolby-vision FTBFS with nocheck build profile: Error: CliError { error: Some(no matching package named `anyhow` found

[Helmut Grohne]

Source: rust-dolby-vision
Version: 3.3.1-1
Severity: serious
Tags: ftbfs
Justification: nocheck ftbfs is release-critical

rust-dolby-vision fails to build from source in unstable when enabling
the nocheck build profile. A build ends as follows.

|    dh_auto_build -O--buildsystem=cargo
|    debian/rules execute_after_dh_auto_build
| make[1]: Entering directory '/build/reproducible-path/rust-dolby-vision-3.3.1'

| As a reminder, you're using offline mode (--offline) which can sometimes cause surprising resolution failures, if this error is too confusing you may wish to retry without the offline flag.), exit_code: 101 }

I guess that too many packages have been annotated <!nocheck>.
