comment Configurations needed for unattended-upgrades to run indefinitely?
For anyone coming along later with a similar question or a similar problem, I discovered that unattended-upgrades failed here not because it ran out of disk space but because it ran of inodes. It ran out of inodes because it never erased uninstalled kernel updates. It never installed the kernel updates because it never restarted. It never restarted either because I did not explicitly configure it to do so, or else because I never installed mailx, so it could not email me to notify me it had restarted. TLDR: unattended-upgrades is not safe & reliable unless you know it very well.

Seems like what I want is provided by nixOS: nixos.org

comment dependency problem prevent upgrade
Not only helped me, it was an enormous relief after hours spent chasing down a long rat-hole of debugging an important prod server. Thanks!

And a closer reading of all the answer's on that link suggests Ubuntu APT repos don't even hold old versions, so I guess Ubuntu just isn't built to facilitate re-creating specific package configurations on demand. Oh well.

(Ah, I see. I thought you were saying Arch & Gentoo allow the system to have two versions of the same package simultaneously installed, rather than allowing you simultaneously to specify multiple packages each with its own version.)

comment How to install specific Ubuntu packages, with exact version?
@user169015 I think you are missing the point of Kyle's comment,. Have a look at psusi's answer below. Apparently the Ubuntu APT repositories do not continue to host old versions of packages! So unlike with runtime package managers (pip, gem, maven, etc.), you cannot rely on the Ubuntu APT repositories if you want to reconstitute an old, known-good configuration. I was surprised and disappointed to realize this myself. Maybe Arch handles this better? ( askubuntu.com/questions/728439/… )

@bodhi.zazen And why would I want to versions at the same time, rather than just the specified version and nothing else?

Thanks. Added an updated to that link. I'm surprised that Arch or Gentoo would do this much better than Ubuntu, just because I'd have assumed Debian already supported this well. But that's why I'm asking the question!

Thanks @LiYong, but using an absolute path gives the same error.
