I’m having trouble staying on top of updates for my self hosted applications and infrastructure. Not everything has auto updates baked in and some things you may not want to auto update. How do y’all handle this? How do you keep track of vulnerabilities? Are there e.g. feeds for specific applications I can subscribe to via RSS or email?

Thank you everyone for the helpful replies!
There are some tools to help, but things are sort of specific to particular aspects. Lynis for general systems, ntopng for networks, and such.
For 90% of stuff, though, you can just stick to stable repos and upgrade on a schedule and you’ll be alright.
I don’t.
Yeah, hot take, but basically there’s no point to me having to keep track of all that stuff and excessively worry about the dangers of modernity and sacrifice the spare time I have on watching update counter go brrrr of all things, when there’s entire peoples and agencies in charge of it.
I just run
unattended-upgrades(on Debian), pin container image tags to only the major version number where available, run rebuild of containers twice a week, and go enjoy the data and media I built the containers and installed for software for.I think the problem is that a lot of people are just running flatpaks, dockers, and third party repos which might not be getting timely updates.
I try to stick to debian packages for everything as much as possible for this reason.
Does badly count as a way?
I kinda keep an eye on that https://selfh.st/ post that does a weekly roundup of stuff to know when I need to do patching.
No doubt there is a container I could run that would do it for me. I just can’t remember the name of it.
i subscribe to the release page of the repo in my rss reader. simple and effective.
95% of things I just don’t expose to the net; so I don’t worry about them.
Most of what I do expose doesn’t really have access to any sensitive info; at most an attacker could delete some replaceable media. Big whoop.
The only thing I expose that has the potential for massive damage is OpenVPN, and there’s enough of a community and money invested in that protocol/project that I trust issues will be found and fixed promptly.
Overall I have very little available to attack, and a pretty low public presence. I don’t really host any services for public use, so there’s very little reason to even find my domain/ip, let alone attack it.
You should try wireguard if you haven’t before, like a breath of fresh air
- VPN only, nothing exposed
- Host runs openSUSE MicroOS which updates itself daily
- Watchtower updates the containers daily and if something blows up so be it, except for Nextcloud as everyone says it’s brittle as hell.
How do I do it? Everything’s installed and updated via pacman/the AUR, including python packages and nextcloud apps. The only thing I don’t install via that way is Firefox addons.
The only thing I don’t install via that way is Firefox addons.
Any specific reason why? Yesterday I installed LibreWolf and saw at the same time a few addons in the AUR.
Do you know what’s the difference from an AUR addon or the official Firefox addon repo?
I guess It would be for security reasons because you never know if someone has tempered with the addon.
Simply because I haven’t bothered searching for the extensions I have in the AUR. And some extensions aren’t in there (namely 7tv, augmented steam, blacklist autoclose, defund wikipedia, kagi, peertube companion, tampermonkey and unload tabs).
XD okay ! Maybe I put to much fought into it 😅
upgrades:
- distribution packages: unattended-upgrades
- third party software: subscribe to the releases RSS feed (in tt-rss or rss2email), read release notes, bump version number in my ansible playbook, run playbook, done.
vulnerabilities:
Unless you have actual tooling (i.e. RedHat erratas + some service on top of that), just don’t even try.
Stop downloading random shit from dockerhub and github. Pick a distro that has whatever you need packaged, install from the repositories and turn on automatic updates. If you need stuff outside of repos, use first party packages and turn on auto updates. If there aren’t any decent packages, just don’t do it. There is a reason people pay RedHat a shitton of money, and that’s because they deal with much of this bullshit for you.
At home, I simply won’t install anything unless I can enable automatic updates. Nixos solves much of it. Two times a year I need to bump the distro version, bump the nextcloud release, and deal with depreciations, and that’s it.
I also highly recommend turning on automatic periodic reboots, so you actually get new kernels running…
That’s the neat part. I don’t!
I have automatic updates on everything, but if I actually spent time managing updates and vulnerabilities I’d have no time to do anything else in my life.
For my docker containers I use what’s up docker which not only alerts me when there is an update but also give a link to the changes, so I can have a look what’s happening !
For my system itself… Just doing
sudo pacman -Syu. Though that’s not great, cause some updates can potentially break my EndeavourOS system… I keep sometimes an eye on the forum when I see some critical changes like the kernel itself or nvidia updates though.I just update every month or two, or whenever I remember. I use Docker/podman, and I set the version to whatever minor release I’m using, and manually bump after checking the release notes to look for manual upgrade steps.
It usually takes 5 min and that’s with doing one at a time.
I have stuff in new releases.io and also GitHub release RSS feeds in nextcloud, I then sit down once a week and see what needs an update. Reboot when required.
Most critical infrastructure like my mail i subscribe to the release and blog rss feed. My OSs send me Update notifications via Mail (apticron), those i handle manual. Everything else auto updates daily.
You still need to check if the software you use is still maintained and receives security updates. This is mostly done by choosing popular and community drive options, since those are less likely to get abandoned.
