On Debian-based distros, when an app is available as a DEB or an AppImage (that doesn't self-update), but no APT repository, PPA or Flatpak, the only option is to manually download each update, and usually manually check even whether there are updates.
But, what if those would be upgraded at the same time as everything else using the tools you're familiar with ?
dynapt is a local web server that fetches those DEBs (and AppImages to be wrapped into DEBs) wherever those are, then serves these to APT like any package repository does.
I started building it a few months ago, and after using it to upgrade apps on my computers and servers for some time, I pre-released it for the first time last week.
The stable version will come with a CLI wizard to avoid this manual configuration.
Feedback is welcome :)
OK. I suppose this is the correct answer.
Unless I'm missing something, here we will disagree. Secure or not, FOSS principle-respecting or not, if I'm choosing to install software by X then I'm going to get it straight from X and not involve third-party Y too.
Source code is like a recipe. Getting your food from the chef who made the recipe is fine, but getting it from another chef who... followed the same exact recipe is no different.
This is how the linux software distribution model works, distro maintainers are a CHECK on upstream.
