Well, I got the debug output this time (a whole megabyte of it, split in two different emails), but unattended-upgrades succeeded, so I still don't know what the original problem was.

Now given that ca-certificates is involved, I suspect this may be related to non-ASCII filenames (see bug 1554365), but unlike that bug, here the upgrade fails instead of succeeding, and the actual error is not shown anywhere.
