Geotrek-admin logs are stored in /opt/geotrek-admin/var/log/geotrek.log
file.
But if Geotrek-admin does not start, take a look to systemd logs for each of the 3 Geotrek-admin services (user web interface, API and asynchronous tasks):
sudo journalctl -eu geotrek-ui sudo journalctl -eu geotrek-api sudo journalctl -eu geotrek-celery
The output is paginated. With -e option you are at the end of the logs but you can go up an down with arrows. Type Q to quit. If you want to copy the log to a file, do:
sudo journalctl -u geotrek-ui > systemd-geotrek-ui.log
django.db.utils.IntegrityError: ERREUR: une valeur NULL viole la contrainte NOT NULL de la colonne « language »
This means specific migrations for translated fields have not been executed on database during update. You have to run them manually, classical migrations included:
geotrek migrate geotrek sync_translation_fields geotrek update_translation_fields geotrek update_geotrek_permissions geotrek update_post_migration_languages
When you try to upgrade your Geotrek-admin, you can have problems with signature check :
An error occurred while checking the signature. The repository is not updated and previous index files will be used. GPG error: https://packages.geotrek.fr/ubuntu bionic InRelease: The following signatures are invalid
You have to update the signature key to get the last update :
wget -O- "https://packages.geotrek.fr/geotrek.gpg.key" | sudo apt-key add -
