Dear Maintainer,

The mplayer package is currently not installable in Sid:

root@vsid:/tmp# apt install mplayer
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libsmbclient : Depends: samba-libs (= 2:4.19.5+dfsg-1) but 2:4.19.5+dfsg-3 is to be installed
 libsmbclient0 : Breaks: libsmbclient (< 2:4.19.5+dfsg-3) but 2:4.19.5+dfsg-1 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.


I guess this problem is related to this change noted in the samba
changelog:

samba (2:4.19.5+dfsg-2) unstable; urgency=medium

  * rename libsmbclient => libsmbclient0 for 64-bit time_t transition
    Closes: #1064337


I rebuilt the mplayer package from source (version 1.5+svn38446) without
any change. The resulting .deb had a dependency on libsmbclient0 (>=
2:4.0.3+dfsg1) and I was able to install it without further effort.

Thank you

With the time_t transition currently going on, expect some breakage in
unstable. Closing this bug as it will be solved when we are ready to
rebuild everything.

Cheers
