How to get the latest version in Xenial

Asked by Marco Lobbia on 2017-09-16

I imagine that when it comes to install software related to server security like rkhunter and chkrootkit it would be better to install the latest version. Please, tell me if I am wrong.

I am on a Ubuntu server 16.04 and noticed that The rkhunter version of the ubuntu package is currently 1.4.0, while the installer is version 1.4.4. I was undecided between installing the outdated ubuntu package or downloading the latest version of rkhunter when I came here and found version 1.4.4 maintained by the Artful Aardvark repository, which is an under development repository.

So, what would you suggest me to do as a better choice for a 16.04 server: install the current Xenial package version 1.4.0, download from the official website the rkhunter-1.4.4.tar.gz file or download from here the Artful Aardvark 1.4.4-3 package?

This would be useful to know not only for rkhunter but also for chkrootkit, since both latest packages come from the Artful Aardvark repository.

Somewhere else I was suggested to download and install the Artful Aardvark package, and, in order to get automatic updates, add the Artful Aardvark repository and do a pinning for the wanted packages.

However, when it comes to updates, nothing would grant that the next version will be from Artful Aardvark.

I would be grateful if you could suggest me the best choice, considering that I am not experienced in editing the /etc/apt/sources.list and pinning.

I suppose that I could as a safe choice install the Artful Aardvark version with dpkg -i if the dependencies are satisfied in Xenial (how can I check this?) and then uninstall with dpkg --remove and reinstall the next version again with dpkg -i. But still I would need some hints on how to do it.

I suggest you report a bug. If the security and bug fixes are significant then the package will be updated sooner rather than later.
Ubuntu does not just update packages because a new version is available. Packages with genuine issues are updated sooner. In Ubuntu, packages sometimes fall behind. It is not a rolling release.

Can you help with this problem?
