Maybe something due to the way your libsolv is configured. Within the build tree, check tests/Testing/Temporary/LastTest.log. It should reveal in detail which checks failed within the tests. If this does not explain the problem one has to dig deeper... (JFYI on vacation till March 6.)

It doesn't seem like a "libsolv is configured wrongly" type of issue.

Here's our libsolv switches (we're on libsolv 0.6.26):

-DFEDORA=1 
-DENABLE_RPMDB=ON 
-DENABLE_RPMDB_BYRPMHEADER=ON 
-DENABLE_RPMMD=ON 
-DENABLE_COMPS=ON 
-DUSE_VENDORDIRS=ON 
-DENABLE_LZMA_COMPRESSION=ON 
-DENABLE_BZIP2_COMPRESSION=ON 
-DENABLE_HELIXREPO=ON 
-DENABLE_SUSEREPO=ON 
-DENABLE_DEBIAN=ON 
-DENABLE_ARCHREPO=ON 
-DMULTI_SEMANTICS=ON 
-DENABLE_COMPLEX_DEPS=1 
-DENABLE_PERL=ON 
-DENABLE_RUBY=ON 
-DENABLE_PYTHON=ON 
-DENABLE_PYTHON3=ON

The LastTest.log file indicates something interesting, though. Each of the failed tests have either zypp::repo::RepoException: Failed to cache repo (129). or zypp::Exception: Failed to cache rpm database (129)..

[mlandres]

Are libsolv tools installed (rpmdb2solv/repo2solv.sh)?
Can you run one of the failing test manually with ZYPP_LOGFILE=/tmp/zypp.log in the environment? The log file should tell what's missing.

@mlandres Ah, that was it. Installing libsolv-tools into the build environment made all the tests pass!

Thanks!
