Describe your issue
When trying to upgrade Seafile from 13.0.12~ynh2 to 13.0.15~ynh1 it doesn’t work, logs are attached.
The problem is that the official Docker image seafileltd/seafile-mc:13.0.15does not exist for the ARM64 architecture. See seafileltd/seafile-mc - Docker Image
The error in your log confirms this:
Getting multi-arch manifest list...
No image digest found. Verify that the image, ref, and platform are valid.
This is a bug in the seafile_ynh package: the manifest.toml declares ARM64 support while the upstream image doesn’t exist for this architecture.
