The insidious urge to fix what ain’t broke has arisen. I’ll probably follow the official documentation, unless someone has a better suggestion.
I’m not running anything unusual and I haven’t done much, if any, “customization”. I update packages maybe a couple of times a week, so they’re current.
Should I go ahead and put myself through this now, or wait until support is dropped and I’m forced?


Thanks for this - I hadn’t seen it yet in the docs I’ve been looking at.
No idea what it does, but it looks legit, so I’ll run it!
Apt v3 comes with some quality-of-life stuff that apt has been direly missing for years, and one of those is apt sources that make sense to a human.
So the new apt source files have local key location, components, suites, and Uris.
The sources from the before-time just had a one-liner with a uri and some components.
Edit:also the modernize command makes a backup of the source files it touches.
