gnocchi-api only supports py3 for now in bionic/queens and above.</p>
<p id="x_m_7540949537711735380m_-2202560929463598836m_-6922203698554669768gmail-yui_3_10_3_1_1528207243272_1630">
Most OpenStack packages in Ubuntu have not yet received py3 support. That is a focus for the cosmic cycle. Where possible the plan is to install py2 by default and py3 as an alternative to prevent all-in-one issues like this.</p>
<p>In other words, 'sudo apt install python3-keystone keystone' would install python3 packages, and (assuming python3-keystone was not already installed) 'sudo apt install keystone' would install python2 packages.<br>
</p>
<p>That's not the case for gnocchi-api, obviously, as it only installs py3 packages which conflicts with other python packages if and only if you're installing on the same machine as other py2 services. Most modern production deployments isolate services in
one way or another (e.g. containers such as LXD or docker) so there's a clear work around.</p>
<p>With that said, we can probably add py2 alternative packages to the Depends for gnocchi-api allowing py2 installs, however I seem to remember gnocchi-api was forced to move to py3 for a reason. I'm not remembering why though atm.</p>
<p>Thanks,</p>
<p>Corey<br>
