AppImage Installer first download working version
In the last few blog posts, mentioned a problem with downloading the latest AppImage file. A version may work, a later version may not. Therefore, the Installer now downloads a known working version.
For the first installation, that is. Later on, there can be a deliberate choice to update to the latest. If the update doesn't work, it is easy to roll back, just by renaming /usr/bin/;lt;app>.binOLD to /usr/bin/

Software development is a social process. What might be a “bug” for someone might well be a “feature” for someone else. The Guix project rediscovered it the hard way when, after “fixing a bug” that had been present in Guix System for years, it was confronted with an uproar in its user base.
In this post we look at why developers considered the initial behavior a “bug”, why users on the contrary had come to rely on it, and why developers remained blind to it. A patch to reinstate the initial behavior is being reviewed. This post is also an opportunity for us Guix developers to extend our apologies to our users whose workflow was disrupted.
