Environment Variables

Note that for Boolean variables we usually test whether the variable exists and not for the assigned value.

zypp config options

• ZYPP_CONF= <PATH> Location of the zypp.conf file.
• ZYPP_LOCK_TIMEOUT= <sec> If zypp is locked by another process wait this number of seconds for the lock becoming available. A negative value will wait forever.

Variables related to repositories

• ZYPP_REPO_RELEASEVER= <ver> Overwrite the $releasever variable in repository URLs and names (

  See also

  zypp::repo::RepoVariablesStringReplacer).

Variables related to commit

• ZYPP_IS_RUNNING=1 Set during commit so packages pre/post/trigger scripts can detect whether rpm was called from within libzypp.
• ZYPP_SINGLE_RPMTRANS=1 Enable alternative and !!!experimental!!! commit strategy where all rpm operations are executed in a single rpm transaction, which results in much faster commits.

Variables related to logging

• ZYPP_LOGFILE= <PATH> Location of the logfile to write or - for stderr.
• ZYPP_FULLLOG=1 Even more verbose logging (usually not needed).
• ZYPP_LIBSOLV_FULLLOG=1 Verbose logging when resolving dependencies.
• (ZYPP_LIBSAT_FULLLOG=1) deprecated since libzypp-10.x, prefer ZYPP_LIBSOLV_FULLLOG
• LIBSOLV_DEBUGMASK= <INT> Pass value to libsolv::pool_setdebugmask

• ZYPP_MEDIANETWORK=1 Turn on the media network backend (the upcoming default).
• ZYPP_MEDIA_CURL_DEBUG=<1|2> Log http headers, if 2 also log server responses.
• ZYPP_MEDIA_CURL_IPRESOLVE=<4|6> Tell curl to resolve names to IPv4/IPv6 addresses only.
• ZYPP_METALINK_DEBUG=1 Log URL and priority of the mirrors parsed from a metalink file.
• ZYPP_MULTICURL=0 Turn off multicurl (metalink and zsync) and fall back to plain libcurl.

• ZYPP_RPM_DEBUG=1 Log verbose output from all rpm commands.

Selecting the mediabackend to use.

• ZYPP_MULTICURL=0 Turn off multicurl (metalink and zsync) and fall back to plain libcurl.
• ZYPP_MEDIANETWORK=1 Turn on the new multithreaded backend (experimental)

Variables related to plugins

• ZYPP_PLUGIN_DEBUG=1 Verbose logging from plugin framework.
• ZYPP_PLUGIN_TIMEOUT= <sec> Send/receive timeout for plugin communication.
• ZYPP_PLUGIN_SEND_TIMEOUT= <sec> Send timeout for plugin communication.
• ZYPP_PLUGIN_RECEIVE_TIMEOUT= <sec> Receive timeout for plugin communication.

• ZYPP_PLUGIN_APPDATA_FORCE_COLLECT=1 Make RepoManager trigger the appdata collector plugin unconditionally. Can be used with 'zypper lr' (as root) to trigger an initial collect rather than calling 'zypper ref -f' or waiting for some repo to be refreshed.

Variables not for common use (test and debug)

• ZYPP_MODALIAS_SYSFS= <PATH> Use this instead of /sys to evaluate modaliases.
• ZYPP_COMMIT_NO_PACKAGE_CACHE=1
• ZYPP_TESTSUITE_FAKE_ARCH Never use this!
• ZYPPTMPDIR= <PATH>
• ZYPP_LOCKFILE_ROOT= <PATH> Hack to circumvent the currently poor –root support.
• ZYPP_PROFILING=1
