Debian 12 ships with Ghostscript 10.00.0, which has a known bug: when pdfa_level is set AND skip_text=true, OCR processing silently fails.

Affected versions: GS 10.00.0 - 10.02.0

Fix (recommended for install.sh on Debian 12):

Activate bookworm-backports and install a fixed Ghostscript version:

echo 'deb http://deb.debian.org/debian bookworm-backports main' >> /etc/apt/sources.list
apt update
apt install -t bookworm-backports ghostscript

This installs GS >= 10.02.1 which does not have this bug.

Workaround (if backports are not available):
Set pdfa_level = "" in the instance config to disable PDF/A output.

Debian 13: Not affected (ships GS 10.05.1).
