SOLVED: Jellyfin App disappeared after Tizen update Samsung TV

[eriksl]

You've tried re-creating a cert?  #3 in our "getting started instructions?
https://developer.samsung.com/smarttv/de...cates.html
https://github.com/jellyfin/jellyfin-tiz...ng-started

<rant>Now I am quite an experienced IT guy (Unix sysadmin, network administrator, software developer in various programming languages), but these descriptions are really hard to follow. If only because the web pages and the program output they refer to have changed, they no longer match. Also there are different approaches that are sometimes hard to distinguish. And of course everything assumes you're running windows.</rant>

Anyway, I deleted everything I had that looked like Tizen and I seem to have been able to install the Tizen stuff again. Including the terrible package manager, the certificate extensions and the Samsung TV extensions. Even though there were some errors along the way, most of which were benign and where able to fix.

I created two certificates as described.

gaia erik:~/tizen-studio/tools/ide/bin $ ./tizen install-permit
Install Permitted

So this seems to work. That's already one step further then before.

But then, exactly the same humbug:

gaia erik:~/tizen-studio/tools/ide/bin $ ./tizen install -n ~/tmp/jellyfin/Jellyfin-10.10.z.wgt -t QE55S95CATXXN

Transferring the package...

No improvement there.

This is interesting too, a command that is suggested as alternative for "tizen install-permit":

gaia erik:~/tizen-studio/tools $ ./sdb push ~/SamsungCertificate/erik-20250208/device-profile.xml /home/developer

Obsolete instruction?
