..my occational workaround, is cheat out apt (or dpkg), adding
an "exit 0" line below any line acting up in any of the relevant
control-the-package script in /var/lib/dpkg/info/$PACKAGENAME.*,
for e.g. zsh, those are: root@d44:~# ll /var/lib/dpkg/info/zsh.*
-rw-r--r-- 1 root root 2569 Apr 27 2020 /var/lib/dpkg/info/zsh.list
-rw-r--r-- 1 root root 3483 Feb 5 2019 /var/lib/dpkg/info/zsh.md5sums
-rwxr-xr-x 1 root root 949 Feb 5 2019 /var/lib/dpkg/info/zsh.postinst

..easier, and disappears on the next upgrade. ;o)

..last year's Knoppix-8.6.1 has a similar problem, it boots with
2 udev processes, each eating 100% cpu of each core, I simply kill
all udev processes and restart the udev service.
Uptime now 51 days 18:30, I haven't gotten around to test the other
isos down my /boot/images. :o)
