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 :)
You said automation breeds laziness (by design, to an extent) and lazy end users tend to shoot themselves in the foot.
So, my question is : what part of automating download of DEBs from a specific source can be shooting oneself in the foot compared to doing the same thing manually every time ?
The MIT license will take care of that.
Also, to force the user to accept and acknowledge that the software they are installing using this tool is not verified to be safe is inducing fear and/or guilt, therefore is bad UX, I'm not doing that.
