Is there something like /etc/os-release for whonix that I can check and compare the versions?
For a “basic” check:
Latest systemcheck points out if the derivative repositories (Kicksecure and Whonix) are enabled or disabled. If the derivative repositories are disabled, a warning is shown by systemcheck. Furthermore, systemcheck also points out if the system is fully updated.
Note: Whonix is based on Kicksecure
For an “advanced”, manual check:
That is a bit difficult for now since we don’t have packages.debian.org APT package repository web interface for deb.whonix.org yet at time of writing.
First, I recommend updating according to documentation: Operating System Software and Updates
Because then you’ll see everything that is happening in detail such as the repositories where packages are fetched from as well as what packages are upgraded. When there is a Point Release you’ll notice a large number of packages being updated.
Does Package Version Check and Repository Version Check help?
I was simply asking about whether my existing whonix-17 template versions are at the newest whonix-17 point release version.
Under debian, you can simply do cat /etc/os-release and see your point release version, like DEBIAN_VERSION_FULL=13.0
We don’t use this.
