I think unattended-upgrades only runs once a day by default, and the repository index could have changed since then. Different results on different machines can be because unattended-upgrades didn’t run at the same time, or from the same mirror (and mirrors take a while to propagate changes). Generally speaking you should always run an apt update directly before installing new packages.










I use mergerfs (and snapraid because I do care about my data and want parity) on ext4 formatted disks. This is a much better way to use your disks if you’re mostly just storing media. RAID is for mitigation of downtime after drive failure, not for joining a bunch of (differently sized?) disks into one pool if downtime isn’t really a problem.
