OK, seems I'm at least half-way through. Now I get: DNA interleaved sequence file, default parameters : Could not create topdir for cache[autopkgtest-lxc-kivtvg:02003] [[INVALID],INVALID] ORTE_ERROR_LOG: Unable to start a daemon on the local node in file ess_singleton_module.c at line 597 [autopkgtest-lxc-kivtvg:02003] [[INVALID],INVALID] ORTE_ERROR_LOG: Unable to start a daemon on the local node in file ess_singleton_module.c at line 168 -------------------------------------------------------------------------- It looks like orte_init failed for some reason; your parallel process is likely to abort.

I remember these messages in connection with some (other?) package on autobuilders but I can't make up my mind which one and I'm obviously doing the wrong web search queries. Any further hints? Thanks so far in any case Andreas. -- http://fam-tille.de
