The general issue is being worked on in scope of MDEV-5252, currently we have a community patch which is awaiting a review.
Elena thanks can you link for the community patch url? would be nice to see progress.

(It can also be found in the first comment to MDEV-5252)
This issue seems to be fixed in the repo.
After all back-and-forth, it seems that the only viable solution we came up with is to release the matching versions of MariaDB server as soon as possible after MySQL 5.5 is released, to prevent the situation when the higher version of MySQL is in the debian/ubuntu repos, while MariaDB is not in ours yet.
We seem to have been more or less successful at that over the past months.
However, with MGC it's not the case yet, it can be released significantly later than the corresponding MariaDB 5.5.x server. So, I'm assigning it to [~nirbhay] to decide how to deal with it in regard to Galera. Please close if there's nothing to do.
what is the best way to handle these issues?
Is it to recommend all users to:
Pinning the MariaDB Repository
Another thing you can do is to pin the MariaDB repository that you use. This is done by creating a file under '/etc/apt/preferences.d/' with the following contents:
Package: *
Pin: origin <mirror-domain>
Pin-Priority: 1000
Replace '<mirror-domain>' with the domain name of the MariaDB mirror you use. For example, 'ftp.osuosl.org'. With the pin file in place, packages from your MariaDB repository will have priority over packages from the system repositories
an apt-get upgrade breaks the mariadb galera cluster rahter often when mysql-common is added to the mix, maybe rename packages?
