I just want to be able to install whatever version of software I need, whenever I want. Package managers need a huge bottom up overhaul. PPAs let me install some of these things, but upgrades demolish thingsI can see them being inconvenient, even dangerous- but they also work.
What would be nice would be for PPA management to be more of a thing. But really, Snaps and Flatpaks are a better solution when available. Not the best, but certainly better.
