Package: gcc-snapshot Version: 1:20190102-1 Severity: normal Hi! While "c++-compiler" is conspicuously missing from Policy's list of virtual packages, it is natural to assume any such package declares an alternative for /usr/bin/c++ -- otherwise, without a common interface, the virtual package would be useless (dependencies are for machines not humans).
Thus, could you please either call update-alternatives, or at least drop the Provides: declaration? While gcc-snapshot is not meant to ever leave unstable, it does satisfy the dependency thus can get pulled into test chroots of packages that are supposed to work with _any_ reasonable C++ compiler.
