Hello
I'm trying to install Flatpak in order to get access to Steam, but it says : error target not found
In Arch the Flatpak is in the Extra repository or KaOS doesn't have that repository installed by default ?
I tried adding [extra] repo to the /etc/pacman.conf file - it couldn't find the repo database

What do I do ?
Thank you very much !

This is not Arch, so best learn what the repo names are, plus what is included and what not.

For flatpak, it is in the apps repo (a normal pacman -Syu, followed by pacman -S flatpak is all that is needed):
https://kaosx.us/packages/packages.php?sortby=&sortdir=&flagged=&page=&repo=&exact=&search=flatpak
But it seems you are trying hard to break your install with adding non-existing, or worse, complete unsupported repositories.....

Thank you for the links
I read the Toolkits page and realized I was missing the [apps] repository - I don't know why
Added it and it all magically worked as expected !

Have a great day !
