 Description   

apt remove <columnstore pkg> will fail if MariaDB is already removed
In mariadb-plugin-columnstore.postrm, we find

# Automatically restart MariaDB after ColumnStore plugin has been removed
 
case "$1" in
 
  purge|remove|disappear)
 
    if [ -d /run/systemd/system ]; then
 
      # If systemd
 
      deb-systemd-invoke restart mariadb.service >/dev/null
 
    elif [ -x "/etc/init.d/mariadb" ]; then
 
      # Fall-back to SysV init
 
      invoke-rc.d mariadb restart || exit $?
 
    fi
 
  ;;
 
esac

If MariaDB is not functional, this fails and apt remove is aborted, making it impossible to remove the package

Thank you for the TIP

commented out the restart function and finally got mariadb uninstalled

was unable to do any updates / installations because apt / dpkg was stuck uninstalling disfunctional "mariadb-plugin-columnstore" package

it should at least have a check to see if mariadb is even running !!!
