<h1><a class="anchor" id="zypp-envars-intro"></a>
Environment Variables</h1>
<p><b>Note</b> that for Boolean variables we usually test whether the variable exists and not for the assigned value.</p>
<h2><a class="anchor" id="zypp-envars-config"></a>
zypp config options</h2>
<ul>
<li><code>ZYPP_CONF=</code> <PATH> Location of the zypp.conf file. </li>
<li><code>ZYPP_LOCK_TIMEOUT=</code> <sec> If zypp is locked by another process wait this number of seconds for the lock becoming available.</li>
</ul>
<h2><a class="anchor" id="zypp-envars-repos"></a>
Variables related to repositories</h2>
<ul>
<li><code>ZYPP_REPO_RELEASEVER=</code> <ver> Overwrite the <code>$releasever</code> variable in repository URLs and names (<dl class="section see"><dt>See also</dt><dd><a class="el" href="structzypp_1_1repo_1_1RepoVariablesStringReplacer.html" title="Functor replacing repository variables.">zypp::repo::RepoVariablesStringReplacer</a>).</dd></dl>
</li>
</ul>
<h2><a class="anchor" id="zypp-envars-commit"></a>
Variables related to commit</h2>
<ul>
<li><code>ZYPP_IS_RUNNING=1</code> Set during commit so packages pre/post/trigger scripts can detect whether rpm was called from within libzypp.</li>
</ul>
<h2><a class="anchor" id="zypp-envars-logging"></a>
Variables related to logging</h2>
<ul>
<li><code>ZYPP_LOGFILE=</code> <PATH> Location of the logfile to write or <code>-</code> for stderr. </li>
<li><code>ZYPP_FULLLOG=1</code> Even more verbose logging (usually not needed). </li>
<li><code>ZYPP_LIBSOLV_FULLLOG=1</code> Verbose logging when resolving dependencies. </li>
<li>(<code>ZYPP_LIBSAT_FULLLOG=1</code>) deprecated since <code>libzypp-10.x</code>, prefer <code>ZYPP_LIBSOLV_FULLLOG</code> </li>
<li><code>LIBSOLV_DEBUGMASK=</code> <INT> Pass value to libsolv::pool_setdebugmask</li>
</ul>
<ul>
<li><code>ZYPP_MEDIA_CURL_DEBUG=<1|2></code> Log http headers, if <code>2</code> also log server responses. </li>
<li><code>ZYPP_MEDIA_CURL_IPRESOLVE=<4|6></code> Tell curl to resolve names to IPv4/IPv6 addresses only.</li>
</ul>
<h2><a class="anchor" id="zypp-envars-mediabackend"></a>
Selecting the mediabackend to use.</h2>
<ul>

<ul>
<li><code>ZYPP_PLUGIN_APPDATA_FORCE_COLLECT=1</code> Make RepoManager trigger the appdata collector plugin unconditionally. Can be used with <code>'zypper</code> <code>lr'</code> (as root) to trigger an initial collect rather than calling <code>'zypper</code> <code>ref</code> <code>-f'</code> or waiting for some repo to be refreshed.</li>
</ul>
<h2><a class="anchor" id="zypp-envars-misc"></a>
Variables not for common use (test and debug)</h2>
