Symbol not found in /usr/sbin/cyrmaster on Ubuntu 18.04

Hi,

This sounds like a problem in the package you're using.

lock_nonblocking() is a macro defined in lib/cyr_lock.h, which just
calls lock_setlock(). If it's trying to resolve "lock_nonblocking" as a
symbol, that suggests something has gone awry in the build.
The locking method is chosen by configure automatically, but can be

--with-lock=METHOD force use of METHOD for locking (flock or
fcntl)

For what it's worth, lock_setlock() is defined in lib/lock_fcntl.c and
lib/lock_flock.c. Depending on configure options/etc, one of these will
be linked into libcyrus_min.so, which I can see in your ldd output so
that's probably not the problem. (Also, it's not complaining about
"lock_set", it's complaining about "lock_nonblocking".)
I don't know much about packaging, but it kind of sounds like the
package has somehow been built with no lock method selected.
It's also interesting to note that you're running "/usr/sbin/cyrmaster"
but it's linking against "/usr/local/lib/libcyrus_min.so.0". Do you
possibly have two different builds of Cyrus installed? (One in /usr, one
in /usr/local.)
Have you reported this on the Ubuntu issue tracker?

Cheers,

For reasons unknown to me, a Google search for the term
lock_nonblocking returns nothing at all related, which I thought
somewhat strange. What am I missing understanding here?>
