# Nextcloud core and app (plugin) versions to install.
# With each version we store a hash to ensure we install what we expect.

# Nextcloud core
# --------------
# * See https://nextcloud.com/changelog for the latest version.
# * Check https://docs.nextcloud.com/server/latest/admin_manual/installation/system_requirements.html
#   for whether it supports the version of PHP available on this machine.
# * Since Nextcloud only supports upgrades from consecutive major versions,
#   we automatically install intermediate versions as needed.
# * The hash is the SHA1 hash of the ZIP package, which you can find by just running this script and
#   copying it from the error message when it doesn't match what is below.
nextcloud_ver=24.0.7
nextcloud_hash=7fb1afeb3c212bf5530c3d234b23bf314b47655a

# Nextcloud apps
# --------------
# * Find the most recent tag that is compatible with the Nextcloud version above by
#   consulting the <dependencies>...<nextcloud> node at:

#   https://github.com/nextcloud-releases/calendar/blob/master/appinfo/info.xml

# We moved to v0.6.3 in 193763f8. Ignore errors - maybe there are duplicated users with the
# correct backend already.

# and there's a lot they could mess up, so we don't make any users admins of Nextcloud.
# But if we wanted to, we would do this:
# ```
# for user in $(management/cli.py user admins); do
#	 sqlite3 $STORAGE_ROOT/owncloud/owncloud.db "INSERT OR IGNORE INTO oc_group_user VALUES ('admin', '$user')"
# done
