Linking not posible

[bstrass]

I installed the bridge (v0.4.3) following the docker guide.
The link command fails with the following error.

Traceback (most recent call last):
  File "/usr/lib/python3.10/site-packages/mautrix/bridge/commands/handler.py", line 491, in handle

Can anyone figure out what's wrong?

That means your homeserver is broken (specifically the media repo)
