I have search the internet and have not found and open source patch management for linux. I am looking for something similar to Ubuntu Landscape, but that can also management and debian-derived distros and rhel as well. Does anyone know of any projects that can be self-hosted? Thanks.
https://theforeman.org/ is one solution. If you know of any other, please reply.
There are services such as https://tuxcare.com/ but Linux is not like Windows where the patch management fails a lot. Most people use things like Debian Unattended Upgrades to avoid unintended consequences to avoid issues.
I have unattended updates enabled for all my servers via ansible. However, it would be nice to see which packages are being updates and if I can role them back for any reason.
By default there is a log of them located here:
