Public bug reported:
After the current update of samba 4.1.6 to 4.3.8 samba on trusty the
BackupPC smb transfer is broken.
Several bugs in smbclient >= 4.1.6 in combination with BackupPC:
https://bugzilla.samba.org/show_bug.cgi?id=11642 (tarmode is no longer
verbose and ignores verbose flag)
https://bugzilla.redhat.com/show_bug.cgi?id=1294761 (mis-interpreted
failure of new tar:\d+ lines) (fix:
https://bugzilla.redhat.com/attachment.cgi?id=1111264&action=diff)
