Bug description:
[Impact]
Upgrading from Xenial/Mitaka to a newer release such as Newton or beyond will break since the newer packages dropped python-swauth package but do not uninstall it resulting in an install conflict. This patch fixes this by ensuring the upgrade uninstalls python-swauth prior to installing new swauth.
[Test Case]
* boot Xenial host
* sudo apt install swauth
* sudo add-apt-repository -y cloud-archive:newton (or whichever we are testing)
* sudo apt update
* sudo apt install swauth (upgrade)
OR
* boot Bionic host
* sudo apt install swauth -ensure it installs cleanly
[Regression Potential]
None envisaged
--------
Versions greater than 1.0.4-0 have dropped the python-swauth package
but do not remove it such that an upgrade breaks with error like:
Unpacking swauth (1.1.0-3~cloud0) over (1.0.4-0ubuntu1.16.04.1) ...
dpkg: error processing archive /var/cache/apt/archives/swauth_1.1.0-3~cloud0_all.deb (--unpack):
trying to overwrite '/usr/lib/python2.7/dist-packages/swauth/__init__.py', which is also in package python-swauth 1.0.4-0ubuntu1.16.04.1
Processing triggers for libc-bin (2.23-0ubuntu10) ...
Processing triggers for man-db (2.7.5-1) ...
Processing triggers for shared-mime-info (1.5-2ubuntu0.1) ...
Processing triggers for sgml-base (1.26+nmu4ubuntu1) ...
Processing triggers for ureadahead (0.100.0-19) ...
Processing triggers for systemd (229-4ubuntu21.2) ...
Errors were encountered while processing:
/var/cache/apt/archives/swauth_1.1.0-3~cloud0_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
If i remove python-swauth prior to upgrade it works just fine.
