package dependencies error with keystone rel. stein

[Robert Holling]

Hi,

I've got an error during a new and fresh installation of Keystone (rel. Stein) on a fresh Ubuntu 18.04.2 LTS.

> the used document: https://docs.openstack.org/keystone/stein/install/keystone-install-ubuntu.html

> I tried the following command:# apt install keystone apache2 libapache2-mod-wsgi

> and got an error: "the following packages have unmet dependencies: keystone: Depends on libapache2-mod-wsgi-py3 but should not be installed."

Here in detail:
After the new installation of Ubuntu 18.04.2, I did all steps as mentioned in the docs:
 # apt install software-properties-common
 # add-apt-repository cloud-archive:stein
 # apt update && apt dist-upgrade
 # apt install python-openstackclient
 # apt install mariadb-server python-pymysql
   >edit the config file /etc/mysql/mariadb.conf.d/99-openstack.cnf
 # service mysql restart
 # mysql_secure_installation
 # apt install rabbitmq-server
 # rabbitmqctl add_user openstack RABBIT_PASS
 # rabbitmqctl set_permissions openstack ".*" ".*" ".*"
 # apt install memcached python-memcache
   >edit the config file /etc/memcached.conf
 # service memcached restart
 # apt install etcd
   >edit the config file /etc/default/etcd
 # systemctl enable etcd
 # systemctl start etcd
   >create database keystone in mysql and grant privs a.s.o.
 # apt install keystone apache2 libapache2-mod-wsgi

I tried everything twice on different nodes with the same result. Previous attempts to repair defective packages led to no result. And it is not the first time, I've installed keystone on ubuntu, but it's the first time on Ubuntu 18.04.2 with Openstack release Stein... :-(

What am I missing?
Any help would be great!

THX
Robert

I couldn't replicate this, did a fresh ubuntu 18.04.2 install and the command ran fine.

Did you install keystone Stein via source code previously to running the install command? The keystone release for 18.04 is Queens (13.0.2). Otherwise I'm not sure yet what is exactly going on here.

[Robert Holling (rholling)]

Thanks for your response, but I'm not entirely with you, I'm sorry.

Keystone 15.0.0 is the current version, corresponding to Openstack Stein -> https://docs.openstack.org/releasenotes/keystone/stein.html

After updating and upgrading the new Ubuntu 18.04.2 I added the repository Stein (add-apt-repository cloud-archive: stein).

What about the following question: Can I install a first system directly with the Stein release, or do I have to install Queens and then migrate to Stein via Rocky?

[Gage Hugo (gagehugo)]

You should be able to install keystone stein release with that method. I will check again with the repo updated to stein from the default one.

[Gage Hugo (gagehugo)]

Ok, can confirm the instructions don't work for stein, getting the same error. Installing libapache2-mod-wsgi-py3 works for me.

This might be problematic for someone still running py2, as this requires python3 installation.

[Colleen Murphy (krinkle)]

I suspect this is a packaging issue and not an issue with the keystone documentation or source code, so tagging the Ubuntu team.

[Robert Holling (rholling)]

this is not a keystone bug, it belongs to the documentation.

[Robert Holling (rholling)]

We checked that yesterday: the second and third parameters of the command are no longer needed, since the mentioned packages are already contained in the parent dependencies.

[Andreas Jaeger (jaegerandi)]

This is a report for the keystone specific documents, not for openstack-manuals.

[Colleen Murphy (krinkle)]

Frank, your proposed fix is not merged yet, did you mean to mark this as "fix committed"? Changing to "in-progress".
