We are running Indigo 2.2.5 on CentOS 7.8. Today I made a back /opt/indico by tar and tried to update to the Indigo 2.3. But it failed and Indico stopped working.
I did not get any errors. I also rebooted the server after update, but still not working. I also tried to do “systemctl daemon-reload” “systemctl restart uwsgi.service” but still not working.
Therefore, I restored from the tar backup.
ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.
We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.
So I stopped here and restored from the tar backup again.
Can I continue to update DB, with this error ?
(I will continue to try tomorrow)
And don’t forget to do a db backup before as well.
Thanks. I did “pg_dump indico > …” everyday by cron.
Also, how exactly did things “not work”?
Internal Server Error, or Service Unavailable at the client browser.
That’s not an error by itself. The problem is that you still have indico-migrate installed:
indico-migrate 1.0.2 requires indico<2.1.dev0,>=2.0, but you'll have indico 2.3 which is incompatible.
Probably from when you migrated from indico 1.2 to 2.0. You’ll never need this tool again, so just get rid of it using pip uninstall -y indico-migrate (there are some leftovers like ZODB, but those are harmless to leave around)
