We have private fdroid repo-s with purging data on s3 on update.
There is issue when you trying to scan qr code and shows invalid signature error.
s3cmd --acl-public \
--add-header='Content-Type: application/java-archive' \
--add-header='Cache-Control: no-store, no-cache, must-revalidate, no-transform' \
--add-header='Pragma: no-cache' \
--add-header='Expires: 0' \
put "${LOCAL_DIR}index.jar" "${S3_TARGET}index.jar" || true
and with other index-v1.jar, index.xml. after purging via:
curl -s "https://" > /dev/null
