===== Problem Locking Files on Remote (smbnetfs) Filesystem =====

Trying to open an XLSX file from a directory mounted via **smbnetfs**, LibreOffice 6.0.7 will complain about not being able to create the **lockfile**. It is not a problem about space or permission, because actually (we used ''strace'' to debug) the lockfile is created, but some other error occurred.

A brutal workaround is to disable lockfile creation system-wide. Just create a file called **/usr/lib/libreoffice/share/registry/disable-file-locking.xcd** with this:

<code xml>
<?xml version="1.0" encoding="UTF-8"?>
<oor:data xmlns:oor="http://openoffice.org/2001/registry">
  <dependency file="main"/>
  <oor:component-data oor:package="org.openoffice.Office" oor:name="Common">
    <node oor:name="Misc">
      <prop oor:name="UseLocking">
        <value>false</value>
      </prop>
    </node>
  </oor:component-data>
</oor:data>
</code>

Another workaround is to let LibreOffice to **talk the smb protocol directly**, without the smbnetfs mount. Just execute the command line:

<code>
libreoffice smb://192.168.1.10/tmp/file.xlsx
</code>

It seems that opening remote files directly requires a recent version of LibreOffice. It seems that version 5.4 should suffice. See the following web resources:
