These libraries are NOT optional with the current 133 build! Upgrading an running C132 firewall system, I can duplicate this error. Once again, commenting the 2> /dev/null saves the day. With the comment removed, this message appears when trying to start Suricata: /usr/bin/suricata: error while loading shared libraries: libjansson.so.4: cannot open shared object file: No such file or directory [ FAIL ] Running: find / -iname "libjansson*" returns nothing. Looks like a missing lib file. Trying the suggested fix: pakfire install jansson PAKFIRE WARN: The pak "jansson" is not known. Please try running "pakfire update". PAKFIRE ERROR: No packages to install. Exiting... Updating mine back to 132 and re-running the update did not help.

Opinions? Best, Matthias
