Source: mdevctl Version: 1.2.0-4 Severity: serious Tags: ftbfs https://buildd.debian.org/status/fetch.php?pkg=mdevctl&arch=arm64&ver=1.2.0-4%2Bb3&stamp=1697626199&raw=0
... Merged Build-Depends: ..., librust-env-logger+default-dev, ... The following NEW packages will be installed: ... librust-env-logger-0.7+default-dev librust-env-logger-0.7-dev ... error: failed to select a version for the requirement `env_logger = "^0.10.0"` ... librust-env-logger-0.7+default-dev providing librust-env-logger+default-dev is also a bug (#1054156), but when mdevctl only accepts 0.10.0 the build dependency should express this by using librust-env-logger-0.10.0+default-dev instead of librust-env-logger+default-dev so that building is not even attempted with an incompatible version.
