In Debian Desktop 12 if I want to do a remote connection as client to a MySQL Server in other machine in the LAN I need use the mysql command, when it is executed happens the following:

manueljordan@vm163:~$ mysql 
bash: mysql: command not found

If is executed the apt search mysql-client command happens the following:

manueljordan@vm163:~$ apt search mysql-client

default-mysql-client/stable 1.1.0 all
  MySQL database client binaries (metapackage)

default-mysql-client-core/stable 1.1.0 all
  MySQL database core client binaries (metapackage)

Therefore:

  • What is the correct package to install? default-mysql-client or default-mysql-client-core? and Why?

And just being curious:

  • What exists two packages?
  • What is the difference between them?

Thanks in advance

The package descriptions should answer your questions (apt show default-mysql-client{,-core}):

  • default-mysql-client shows

    This package depends on the default implementation of the client binaries and the additional tools innotop and mysqlreport.

  • default-mysql-client-core shows

    This package depends on the default implementation of the core client files, as used by Akonadi.

So if you want innotop and mysqlreport, install default-mysql-client; otherwise, install default-mysql-client-core.

Note that both packages are metapackages, pulling in the corresponding MariaDB packages. They were added to facilitate migration from MySQL to MariaDB; details are in the release proposal.

  • Than you. It seems the first options is better ... because I found Akonadi and MySQL bug Commented Apr 7 at 18:14
  • The first package ends up installing the -core packages anyway, that wouldn’t make a difference. Commented Apr 7 at 18:40
  • How did you get that conclusion? I executed the apt show default-mysql-client command and is indicated Depends: mariadb-client. Or Did you execute other command? Commented Apr 7 at 19:08

    default-mysql-client is an empty package depending on mariadb-client, which depends on mariadb-client-core; default-mysql-client-core is an empty package depending on mariadb-client-core. So both packages end up installing mariadb-client-core, and if that causes issues with Akonadi, you’ll run into it either way. However the bug you found was fixed in 2020 so I don’t think it’s relevant. Commented Apr 7 at 20:46
  • Thank You. I confirmed the chain of dependencies of each one. Now I am going to research about: Why is created from the beginning an empty package? What is its purpose to exists Commented Apr 8 at 21:24

This answer is the accepted one (with good reason), but I want to mention that the Debian Package Server is a good resource to answer similar questions you may have in the future about the contents of packages and what dependencies a package may have.

The url is: https://packages.debian.org/

(Ubuntu maintains one for Ubuntu distros as well: https://packages.ubuntu.com/)
