Clean install of openvas9 | 7.0.3-2bionic (on Ubuntu 18.04.1 LTS).
Upon finishing, NVT cache won’t generate, even after scanner has been started and openvasmd --rebuild has been run (NOTE: did have to perform kb_location = /var/run/redis/redis.sock fix to be able to start the scanner).
Here’s the output of openvas-check-setup:
Step 1: Checking OpenVAS Scanner …
OK: OpenVAS Scanner is present in version 5.1.3.
OK: redis-server is present in version v=4.0.9.
OK: scanner (kb_location setting) is configured properly using the redis-server socket: /var/run/redis/redis.sock
OK: redis-server is running and listening on socket: /var/run/redis/redis.sock.
OK: redis-server configuration is OK and redis-server is running.
OK: NVT collection in /var/lib/openvas/plugins contains 47718 NVTs.
WARNING: Signature checking of NVTs is not enabled in OpenVAS Scanner.
SUGGEST: Enable signature checking (see http://www.openvas.org/trusted-nvts.html).
WARNING: The initial NVT cache has not yet been generated.
SUGGEST: Start OpenVAS Scanner for the first time to generate the cache.
Step 2: Checking OpenVAS Manager …
OK: OpenVAS Manager is present in version 7.0.3.
OK: OpenVAS Manager database found in /var/lib/openvas/mgr/tasks.db.
OK: Access rights for the OpenVAS Manager database are correct.
OK: sqlite3 found, extended checks of the OpenVAS Manager installation enabled.
OK: OpenVAS Manager database is at revision 184.
OK: OpenVAS Manager expects database at revision 184.
OK: Database schema is up to date.
ERROR: The number of NVTs in the OpenVAS Manager database is too low.
FIX: Make sure OpenVAS Scanner is running with an up-to-date NVT collection and run ‘openvasmd --rebuild’.
… and yes, I have both run greenbone-nvt-sync and restarted the scanner. Multiple times. NVTs still don’t get added to /var/lib/openvas/mgr/tasks.db.
Checking openvassd.messages it looks like openvassd is having a segmentation fault while doing a call to /usr/lib/x86_64-linux-gnu/libopenvas_base.so.9 in Ubuntu 18:

SIGSEGV does NOT happen with openvas9 | 7.0.3-1 running on Ubuntu 16, it is specific to openvas9 | 7.0.3-2bionic on Ubuntu 18.
Any ideas on what is causing this SIGSEGV and how to fix this?
