You might want to run 'apt --fix-broken install' to correct these.

mysql-community-server : Depends: mysql-client (= 5.7.22-1debian7) but 5.7.32-1debian9 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
如果我运行它sudo apt --fix-broken install它会显示
dpkg: warning: subprocess old pre-removal script returned error exit status 5
