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_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_RPM_DEBUG=1 Log verbose output from all rpm commands.

Selecting the mediabackend to use.

  • ZYPP_CURL2=<0|1> Switch between Curl and Curl2 media backends, Curl2 is the default.
  • ZYPP_PCK_PRELOAD=<0|1> Explicitly turn parallel HTTP package downloads for commit on or off.

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>
