[Pkg-samba-maint] Bug#953530: Downstream bug LP: #1886114

[Bryce Harrington]

Fwiw, ubuntu reporters have hit this issue as well:

  https://bugs.launchpad.net/debian/+source/samba/+bug/1886114

We've not yet reproduced the error about /run/samba, but I found one way
to make it fail to get into an installation failure state:

$ sudo apt-get install samba
$ sudo apt-get remove --purge samba-common-bin
$ sudo rm -rf /run/samba
$ sudo rm -rf /etc/samba
$ sudo apt-get install samba-common-bin
Reading package lists... Done
...
Setting up samba-common-bin (2:4.13.3+dfsg-1ubuntu2) ...
Checking smb.conf with testparm
Load smb config files from /etc/samba/smb.conf
Error loading services.
dpkg: error processing package samba-common-bin (--configure):
 installed samba-common-bin package post-installation script subprocess returned error exit status 1

After this it will continue to exhibit error messages similar to what
other reporters have seen.

To restore the system back to working order, this seems to do it:

$ sudo apt-get remove --purge *samba*
$ sudo apt-get install samba

I tried tampering with and removing /run/samba at various points, and
tinkering with /usr/lib/tmpfiles.d/samba.conf in various ways, but
wasn't able to generate the "lock directory /run/samba does not exist"
issue.

I also tested the above with 2:4.11.6+dfsg-0ubuntu1.6, and found it
gives identical behavior as above.
