Seems ok when just upgrading the py2 package from queens->rocky manually
with:
$ sudo add-apt-repository cloud-archive:queens
$ sudo apt update
$ sudo apt install openstack-dashboard
$ ls -al /usr/share/openstack-dashboard/
$ ls -al /usr/share/openstack-dashboard/openstack_dashboard/
$ sudo add-apt-repository cloud-archive:rocky
$ sudo apt update
$ sudo apt dist-upgrade --yes
$ ls -al /usr/share/openstack-dashboard/openstack_dashboard
lrwxrwxrwx 1 root root 37 Feb 14 19:26 /usr/share/openstack-dashboard/openstack_dashboard -> /etc/alternatives/openstack_dashboard
$ ls -al /usr/share/openstack-dashboard/openstack_dashboard/

Title:
Upgrade from rocky python2->python3 packages breaks
openstack_dashboard alternative
Status in OpenStack openstack-dashboard charm:
New
Status in horizon package in Ubuntu:
New
Bug description:
After upgrading from queens->rocky with the openstack charms,
/usr/share/openstack-dashboard/openstack_dashboard is missing files
because it is not a symlink (alternative) to /usr/lib/python3/dist-
packages/openstack_dashboard.
Note that the openstack charms are using py2 packages in queens and
py3 packages in rocky. The upgrade process of the packages goes:
(1) py2queens -> (2) py2rocky -> (3) py3rocky
Bad state after upgrade: https://paste.ubuntu.com/p/3GnMTVfZDk/
Also worth noting that the queens packages did not use alternatives
for /usr/share/openstack-dashboard/openstack_dashboard. In that
version of the package the files are copied into /usr/share/openstack-
dashboard/openstack_dashboard during the package build so there are no
symlinks/alternatives involved.
Looking closer during the upgrade..
After step (1) we have:
$ update-alternatives --display openstack_dashboard
juju-45afee-coreycb2-31: Thu Feb 14 19:03:22 2019
update-alternatives: error: no alternatives for openstack_dashboard
