akonadi-server too dependent on MySQL and prevent percona instalation

Confirmed, this bug prevents users from replacing mysql with percona packages. A quick fix is to extract akonadi -backend-mysql page, modify control file (change Depends), repack .deb file and reinstall (the solution below is more or less working - I'm tweaking the Depends section now)

apt-get install --reinstall --download-only akonadi-backend-mysql
mv /var/cache/apt/archives/akonadi-backend-mysql_1.12.1-0ubuntu1.1_all.deb .
ar x akonadi-backend-mysql_1.12.1-0ubuntu1.1_all.deb
tar xvzf control.tar.gz
vi control
Depends: virtual-mysql-server-core | mariadb-server-core-5.5 | percona-server-server, mysql-client-core-5.5 | mariadb-client-core-5.5 | percona-server-client-5.6, libqt4-sql-mysql
rm control.tar.gz
tar c postinst postrm md5sums control conffiles | gzip -c > control.tar.gz
ar rcs akonadi-backend-mysql_1.12.1-0ubuntu1.1_percona_all.deb debian-binary control.tar.gz data.tar.xz
dpkg -i akonadi-backend-mysql_1.12.1-0ubuntu1.1_percona_all.deb

apt-get install percona-server-server-5.6 percona-server-client-5.6

For the above to work with percona-server, control file in percona-server-server package MUST list , mysql-server-core-5.5, mysql-server-core-5.6 in both Replaces and Provides sections

Status changed to 'Confirmed' because the bug affects multiple users.

This bug was fixed in the package akonadi - 1.13.0-2ubuntu3

---------------
akonadi (1.13.0-2ubuntu3) vivid; urgency=medium

  * Still prefer mysql 5.6, but allow any mysql implementation that provides
    virtual-mysql-server-core and virtual-mysql-client-core
    (LP: #1336005)
  * Force dependency on akonadi-backend-mysql for akonadi-server.
    (was accidentally dropped in the last debian merge)

Can we expect to see this in trusty?

+1 for trusty, can't work without it

Any chance this can also be updated to support MariaDB installations? Or is there an alternate way for MariaDB to provide virtual-mysql-[client|server]-core to satisfy akonadi-backend-mysql's dependencies?

Scratch that -- I'm running MariaDB's own .debs instead of Ubuntu's; it looks like the stock Ubuntu .debs are set up properly.

For me this is still the case. Default shoud be sqlite because no further configuration is required.
