Lynis on Ubuntu 18 out of date

Tue Oct 8 03:59:14 UTC 2019

Folks

I noticed that my Lynis utility, which I don't use that much, was sending me messages & I thought I'd install it via apty instead of the tarball version. However the version in the Ubuntu repos is v2.6.2 while the latest actual version is 275 released on  2018-02-13.

Does anyone know why Ubuntu is lagging so far behind? Is Lynis deemed to be unnecessary? Is there something better?

Thanks

Ian
