Hi there,

Trying to install MariaDB 10.7.3 using the official procedure (ref. https://mariadb.com/kb/en/installing-mariadb-deb-files/#installing-mariadb-packages-with-apt) on Ubuntu 21.10 Server (Impish Indri) for system architecture arm64 the following problem appears, preventing the installation to complete successfully:

Some packages could not be installed. 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

The following information may help to resolve the situation:

*The following packages have unmet dependencies:
mariadb-client : Depends: mariadb-client-10.7 (>= 1:10.7.3+maria~impish) but it is not installable
mariadb-server : Depends: mariadb-server-10.7 (>= 1:10.7.3+maria~impish) but it is not installable
E: Unable to correct problems, you have held broken packages.*

Kindly note that I already opened another similar bug report, MDEV-26024 less than a year ago, on June 2021.

It seems you may have you automatic build workflow for arm64 broken somewhere, as the problem also happened on 10.6

Thank you!
