Comment 2 for bug 1982582

I can confirm and recreate this problem.

It's a problem with the kdump-tools post-inst script:
"
ErrorMessage:
 installed kdump-tools package post-installation script subprocess returned error exit status 2
...

              the script did not pass --debconf-ok to ucf. The maintainer^M
              script should be fixed to not stop debconf before calling ucf,^M
              and pass it this parameter. For now, ucf will revert to using^M
