Can't install Jellyfin on my new roku
I can't find the Jellyfin channel in search on the Roku itself, or in the channel store.
I've seen youtube videos showing people testing jellyfin, so I know it at least used to exist.
Has it been removed from the Roku ecosystem?
In addition to the current info/issue pointed out by renojim in the above link, you can also just use Jellyfin as a DLNA server through Roku Media Player (RMP).
There are two methods to use Jellyfin on Roku. Can use the Jellyfin channel/app on Roku, or as a DLNA server available under under RMP. (do not need to install the channel/app in order to use Jellyfin on Roku). The different methods do have different interfaces though. I will note that Jellyfin seems to fail to populate as an available server quite often on my Roku devices, but a simple typed command to "restart" the server fixes it immediately and refreshes the server under RMP. (for Linux, just type sudo systemctl restart jellyfin). For Windows, the server apparently can be stopped, then restarted under Services tab.
