[SOLVED] Can't install a Flatpak game

[oldgeek]

I'm trying to install Warble, a Flatpak game similar to Wordle. I first read of this on Linus Links, and installed it successfully on my 22.10 setup without problems, following the instructions in the article. Due to HD death, I'm trying to recover what I had before, but so far I can't seem to install this nice little game. Here's what I get:

steve@steve-B460MDS3HV2:~$ flatpak install flathub com.github.avojak.warble
Looking for matches…
error: No remote refs found for ‘flathub’

Am I missing some repository? I'm using 22.10 freshly installed.

See https://flatpak.org/setup/Ubuntu

You need to add the flathub repository first.

You have to add the Flathub repo in Konsole first as Snowhog said:
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

and if you have not installed the Flatpak support for Discover yet (so you can browse/install/update Flatpaks in Discover):
sudo apt install plasma-discover-backend-flatpak

Thanks to you both for responding. I now have the game installed. Love this forum!

Had some difficulty setting up flatpak to install JASP, finally found the answer in this thread. Thanks again.
