Hi Ralf, according to CHANGES: ## 2017/04/18 * Changed Menhir's license from QPL to GPLv2. MenhirLib remains under LGPLv2, with a linking exception. so I guess your debian/copyright needs an update. Thanks! Thorsten === Please feel free to respond to this email if you don't understand why your files were rejected, or if you upload new files which address our concerns.
