I'm not sure what the package availability is on Ubuntu, but on Fedora we
no longer use the mysql client, but use the mariadb one which provides the
same capability:

$ dnf --repoid=rawhide repoquery --provides mariadb-connector-c
libmariadb.so.3
libmariadb.so.3()(64bit)
libmariadb.so.3(libmariadb_3)
libmariadb.so.3(libmariadb_3)(64bit)
libmariadb.so.3(libmariadbclient_18)
libmariadb.so.3(libmariadbclient_18)(64bit)
libmariadb.so.3(libmysqlclient_18)
libmariadb.so.3(libmysqlclient_18)(64bit)
mariadb-connector-c = 3.1.8-1.fc33
mariadb-connector-c(x86-32) = 3.1.8-1.fc33
mariadb-connector-c(x86-64) = 3.1.8-1.fc33

Thanks,
Richard
