 Description   

After upgrading mariadb to 10.2.9 i get the following error:

Sep 28 09:34:07 ns1 pdns_server[12841]: Sep 28 09:34:07 Unable to load module '/usr/lib/x86_64-linux-gnu/pdns/libgmysqlbackend.so': libmariadbclient.so.18: cannot open shared object file: No such file or directory

/usr/lib/x86_64-linux-gnu/libmariadbclient.so.18 isn't anymore there.

Hotfix:

ln -s libmariadb.so.3 /usr/lib/x86_64-linux-gnu/libmariadbclient.so.18

This was most probably caused by fixes in debian packaging in 10.2.9.

in 10.2.8 and earlier, libmariadb3 package installed libmariadbclient.so.18 and libmysqlclient.so.18 symlinks, and libmariadbclient18 and libmysqlclient18 packages were empty. They depended on libmariadb3, so if one would install libmariadbclient18, she'd get symlinks all right. The problem was that after that, if one would remove symlinks and reinstall libmariadbclient18 — symlinks wouldn't come back. The fix was to move symlinks to their corresponding packages, in 10.2.9 libmariadb3 package installs only libmariadb.so.3, while libmariadbclient.so.18 is installed by libmariadbclient18 package (that's why reinstall helped).

This doesn't explain, though, why libmariadbclient.so.18 disappeared for you. If you could tell how to repeat this effect, I'll be able to fix it.

I only upgraded the Packages.

apt update
 
apt upgrade

After that the softlink was deleted on 6 diffrent server.

Someone has the same problem: https://jira.mariadb.org/browse/MDEV-13588?focusedCommentId=100873&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-100873

Yes, that was exactly the issue we've fixed in 10.2.9, it was MDEV-13589. The scenario was explained in this comment. And underlying reason was that libmariadbclient18 package was empty, it did not install libmariadbclient.so.18 symlink. This was fixed in 10.2.9.

serg, if this question is still open, it's reproducible rather easily without removing the symlinks.
