We are running Train on Centos 7, but I'm experimenting with Adjutant under Ussuri on Centos 8. Until yesterday my Ussuri Horizon containers were ok, but after the Centos 8.3 release they started failing with "{"log":"CommandError: An error occurred during rendering /var/lib/kolla/venv/lib/python3.6/site-packages/openstack_dashboard/templates/horizon/_scripts.html: Couldn't find any precompiler in COMPRESS_PRECOMPILERS setting for mimetype '\\'text/javascript\\''.\n","stream":"stderr","time":"2020-12-08T20:08:03.267208752Z"}" I dug through the Centos release notes and didn't find anything there. [1] I already have the "lowercasing" issue fixed [2]. I see the javascript reference in _scripts.html [3] but it's not obvious what is going wrong. How can I work around this? Is there a variable I can set to build the container on Centos 8.2? Or is there a better way? More logs at [4] [1] https://wiki.centos.org/Manuals/ReleaseNotes/CentOS8.2011 [2] https://review.opendev.org/c/openstack/kolla/+/765854 [3] http://paste.openstack.org/show/800896/ [4] http://paste.openstack.org/show/800897/ I apologize for the nonsense below. So far I have not been able to stop it from being attached to my external emails. I'm working on it.
