If you can, its recommended to use Suricata-Update instead of curl, unless you have a strong reason to do so.
At the end of the ./configure
there should be something about why suricata-update
was not installed. Probably a missing dependency. Might be worth trying to fix that.
eg)
Python support: yes
Python path: /usr/bin/python3
Python distutils yes
Python yaml yes
Install suricatactl: yes
Install suricatasc: yes
Install suricata-update: no, not bundled
