Description
(maybe it wasn't supposed to, need to check, but from dependencies it looks like it should).
apt-get install mariadb-server (from 5.3.33 repo)
works all right
switch to 5.5 repo,
apt-get install mariadb-server
says it's already on the newest version.

So, it was a result of the trade-off we made in 5.5.31, when we renamed our packages to solve th eproblem with conflicting MariaDB 5.5.x / MySQL 5.5.x versions. We used to have mariadb-server-5.5_5.5.28-mariadb1~wheezy_..., and with 'a' it would become mariadb-server-5.5_5.5.28-mariadb-a1~wheezy_..., and it seemed to work.
Then we started naming them mariadb-server-5.5_5.5.33+maria-1~wheezy_..., and with 'a' it would become mariadb-server_5.5.33a+maria-1~wheezy_, and it didn't work on the reason Matt explained above.
I don't think we should rename packages again, as I'm sure we'll get into some unexpected trouble whichever naming scheme we choose; we just need to remember about the problem and next time we decide to re-release packages of the same version, come up with something better than mariadb-server_5.5.Xa+maria-1...
Sergei Golubchik, FYI ^
With that, I'm closing the issue as 'Won't fix'.
This is due to the sorting algorithm used by dpkg. From Debian Policy (http://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Version): "The lexical comparison is a comparison of ASCII values modified so that all the letters sort earlier than all the non-letters and so that a tilde sorts before anything, even the end of a part." So, when APT compares the versions "5.5_5.5.33+maria-1~wheezy" and "5.5_5.5.33a+maria-1~wheezy", "5.5_5.5.33a+maria-1~wheezy" is considered earlier because the sort algorithm places "a" before "+".
Since the packages are named "mariadb-*", do we really need "+maria" in the version?
