Describe the Bug

UDM Pro (version 1.12.30) does not install the script. It seems that "stretch" has been archived

Expected Behavior

installation of the script

This is not a udm-iptv issue but a UniFi OS issue. UniFi OS 1.12.30 is two years old. Upgrade to a newer version of UniFi OS and try installing the script again.

[xelAresU]

Thx. I will look into it. I had the UDM on for several hours with auto-update enabled. I assumed it had updated to the latest version in the meanwhile...

[erikpost]

The most recent official Unifi OS version for the UDM Pro is version 4.0.20, released in October 2024. Not sure why it didn't update automatically but you're quite a bit behind 😁

[xelAresU]

Yup, I went through at least 5 update cycles this afternoon. I had to force the update with ssh. The UI did not recognize the new version. Unfortunately Christmas eve stopped me from executing the script... To be continued

As far as I remember, the script doesn't support UniFi OS version 1.12.30 anymore. Let me know if you had success upgrading to a more recent image.
