This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libmysqlclient-dev : Breaks: libmysqld-dev (< 8.0) but 5.7.26-1+b1 is to be installed E: Unable to correct problems, you have held broken packages. Quickly looking at the mysql-8.0 sources there seems to be a lot of files that have been moved around, changed paths etc. I hope you have a good CI setup to verify all those changes were made in a backwards compatible way.
