Here's the sequence of what I did: I wrote to the list each time, so I know the exactly when.

4 January 2020: migrate from debian/stretch to beowulf
https://lists.dyne.org/lurker/message/20200104.101800.7b0f18cb.en.html
Beowulf was the stable version at the time. Afterwards, I upgraded it regularly and smoothly.


19 April 2021: upgrade from beowulf to chimaera.
https://lists.dyne.org/lurker/message/20210419.111049.2c050382.en.html
As I wrote at the time:

     Everything incredibly smooth!

     I don't know why I rebooted between upgrade and dist-upgrade.  The graphics
     didn't come up, so I run dist-upgrade on the tty terminal.  That's the only
     annoyance I had.

     Heck, the process took an inordinate amount of time.  autoremove is still
     running for 435 packages... Isn't there a way to remove packages not used
     for more than one year?

24 June 2021: apt-get update + apt-get upgrade
https://lists.dyne.org/lurker/message/20210625.093432.02c220e2.en.html
I hadn't updated the system since April.

Network printer and usb key access were damaged by the upgrade. I'm sure I used both between Apr 19 and Jun 24. For the printer, I just deleted and discovered it again. For spacefm, I installed udevil. I found no relevant differences in spacefm dependencies. I'm not sure whether udevil was installed before (it is suggested). Perhaps usb access was granted in some other way.

After looking for timestamps, I don't think I used Inkscape or MariaDB during that period. Perhaps those packages were removed during the April upgrade and I only noticed after the June upgrade.

They look clean. The only file in sources.list.d, mptcp, was commented out in April, before doing the upgrade. I attach both.

   3408640      4 -rw-r--r--   1 root     root         1032 Apr 19 09:28 /etc/apt/sources.list
   3409224      4 -rw-r--r--   1 root     root           65 Apr 19 09:24 /etc/apt/sources.list.d/mptcp.list

No idea. Didn't remove them intentionally. Not even sure /when/ they were removed.

Ok, lesson learned.

However, apt should still keep back unupgraded packages, so that if you issue a dist-upgrade afterwards, it can find them and upgrade them, correct?

Thanks a lot for explaining.
