does/should it work with python <3.8?

[DJCrashdummy]

beforehand: i'm not sure where this issue fits the best (here or at @lekma's fork or perhaps even at his addon repo), so please bear with me.

---

i'm using the latest OSMC (2022.03-1) which uses Kodi 19.4 and is based on Debian 10 Buster. the addon from the official repo (0.1.0+matrix.1) can be installed, but if i try to send any request to the chosen invidious instance - no mater which one - i get a 403 response.
because it seems a little bit outdated, i activated/installed @lekma's addon repo, installed it's latest version (1.0.10), but then i just get an error notification to look at the logs for further information... the things about invidious:

unfortunately i'm not a dev, but my uneducated guess is that this addon - at least all version in @lekma's addon repo - uses/assumes python 3.8 but Debian Buster provides only python 3.7 (3.7.3-1 in my case to be precise).

if i'm correct, is there any chance to get this addon working with python <3.8 (with reasonable effort)? or is there a way to install the needed dependencies resp. check them beforehand and avoid installing/updating if they are not met?

Your guess is right. This is some new Python 3.8 syntax which I hadn't ever seen before this issue. The specification is in https://peps.python.org/pep-0572/.

This is the wrong repository, though. The file layout (service.py) suggests you need to look for some other repository.

thanks for the quick reply @TheAssassin! sorry for bothering you with this... somehow i thought this two projects are closer related. :facepalm: my bad!

[DJCrashdummy]

but still the 403 error (with the version from the official repo) persists... is there a chance to get the official repo updated?
