Public bug reported:
containerd release 1.5.2-0ubuntu1~20.10.2 addressing USN-5102-1 in focal
includes a "Breaks" reference to a docker.io package version
(19.03.8-0ubuntu1.20.04.2) that was never released. Currently only .1 is
available not .2.
$ dpkg -I /var/cache/apt/archives/containerd_1.5.2-
As far as I'm concerned this is a packaging bug plain and simple.
There's no reason to have the python-scipy package depend upon python-
decorator/python3-decorator with a fragile symlink.
Upstream scipy 0.17.0 does not symlink decorator.py it vendors a working copy:
