You might want to run ‘apt --fix-broken install’ to correct these.
The following packages have unmet dependencies:
mariadb-server-10.3 : Depends: mariadb-client-10.3 (>= 1:10.3.34+maria~focal) but 1:10.3.34-0ubuntu0.20.04.1 is installed
mariadb-server-core-10.3 : Breaks: mariadb-client-10.3 (< 1:10.3.34+maria~focal) but 1:10.3.34-0ubuntu0.20.04.1 is installed
E: Unmet dependencies. Try ‘apt --fix-broken install’ with no packages (or specify a solution).

And if there is any other way to resolve this issue, please help.
