Known Issues

Current limitations of ARM v3, with workarounds where they exist. For in-the-weeds debugging see Troubleshooting; for what's planned see the Roadmap.

v3 is under active development. Expect rough edges, breaking changes between versions, and incomplete docs.

Published images may not exist for every tag yet. the image pull (armctl up / armctl upgrade) can return 404 during the alpha. Build the images locally from a checkout — see Local development in the README.

Windows / macOS can't rip. Docker Desktop can't pass an internal SATA optical drive into its Linux VM. You can run the UI + transcoder as a library-management frontend (over a WSL2-native path, a named volume, or an SMB mount — not an NTFS C:\... bind mount, where file ownership is faked), but ripping requires a Linux host.
TrueNAS, Kubernetes/Helm, and Podman are not supported. TrueNAS in particular is explicitly out of scope — please don't file bugs against it. Unraid and Synology run stock Docker and work.

Desktop hosts need auto-mount disabled to eject. On a host with a GNOME/ KDE/XFCE session, udisks2/gvfs grabs the disc and the ripper can't eject after a rip. With your consent, the installer writes a host-wide udev rule that stops auto-mounting of optical discs; if you declined it, installed manually, or eject still fails, see Troubleshooting § Disc won't eject.
No database schema rollback. Alembic downgrade across versions isn't supported — back up Postgres before upgrading if you want a safety net. See Upgrading.
MakeMKV beta binary expiry. MakeMKV beta binaries self-expire (~60 days), which blocks Blu-ray/UHD reads (DVDs are unaffected) until upstream ships a new beta and the ripper image is rebuilt. No registration key overrides this. See MakeMKV.

Ripping from an .iso file (vs a physical disc) is designed but not implemented as a user-facing feature. ARM can produce an .iso from a disc today. See Roadmap.
