NameError: name 'instance_id' is not defined

[obrain17]

If you run the avahi-linker in Python 3.10 (with Ubuntu 22.04) or Python 3.12. (with Ubuntu 24.04) the recordings will not be updated if config.dbus2vdr is True. Only the method using svdrp_con.sendCommand("UPDR") will work.

This is because the variable instance_id is not defined:

Traceback (most recent call last):
  File "/usr/bin/avahi-linker", line 210, in <module>
    vdr_bus_name = f"de.tvdr.vdr{instance_id if instance_id else ''}"
NameError: name 'instance_id' is not defined

same for line 707.

This message, however, is not displayed in normal run, because both occurrences are within a try: block.

I have created a fix for this: https://github.com/obrain17/avahi-linker-fix-instance_id/blob/master/usr/bin/avahi-linker. On my side it works in both Ubuntu environments mentioned above.

@seahawk1986: You might check this on your side first please, and then let me know if I should create a PR or you will “pull” it yourself.

BTW: another topic I found: The script prevent-umount-on-pause wants to

import dbus2vdr

but python3-dbus2vdr gets only installed in setup-xorg.yml, which does not run with a headless installation. Probably it could be added or moved to ‘apt’ task in roles/yavdr-network/tasks/main.yml.

Thank you very much for providing Ansible playbooks for yaVDR. I just have installed the headless version on the new Ubuntu server “noble” 24.04 using your “dists” for noble.
