How to Install Transmission to OS 5?

Hi,
I’ve upgraded from os 3 to os 5. But Transmission app is lost. How can I re-install it? It doesn’t available in my app dashboard.
Thanks.

It seems so. But I was able to install it to os 3

Welcome to OS5…
I came from My Cloud Home so that was an improprement, despite the long wait for the indexing.
I saw many complain coming from OS3.

Transmission was not officially supported on a single bay OS3 My Cloud.

It likewise is not officially supported on a OS5 second gen single bay My Cloud.

However, it may be possible to unofficially install a version of Transmission on on a OS5 second gen single bay My Cloud. See this post and those that follow it in this OS3 thread:

As always, you proceed at your own risk when it comes to unofficial apps and modifications.
