Comment 0 for bug 1892448

On an Ubuntu 20.04 installation with the focal-proposed repo enabled and both the ceph/ceph-base/ceph-* packages (which are in main) and the ceph-deploy package (which is in universe) installed, the upgrade from ceph 15.2.3-0ubuntu0.20.04.1 to ceph 15.2.3-0ubuntu0.20.04.2 breaks with the following error message:

dpkg: error processing archive /var/cache/apt/archives/ceph-base_15.2.3-0ubuntu0.20.04.2_amd64.deb (--unpack):
 trying to overwrite '/usr/share/man/man8/ceph-deploy.8.gz', which is also in package ceph-deploy 2.0.1-0ubuntu1

I wasn't even able to solve this by trying to uninstall/purge ceph-deploy using apt-get or aptitude - instead, I had to resort to

dpkg --remove --force-remove-reinstreq ceph-deploy

I think this is a bug in ceph 15.2.3-0ubuntu0.20.04.2, more specifically in the packaging of ceph-base 15.2.3-0ubuntu0.20.04.2, which probably shouldn't contain the man page for ceph-deploy since it doesn't seem to contain any other ceph-deploy files either.
