Failed to uninstall and reinstall on PureOS - linux-headers-5.10.0-28-amd64 missing

I'm on still on PureOS 10 – Byzantium (based on Debian 11 - Bullseye). After installing the last system updates, display link stopped working. I tried to uninstall and reinstall, but already the uninstall fails with:

sudo ./displaylink-debian.sh
