error: Nothing matches org.gnome.Sdk in remote flathub-beta

[juk0de]

Hi! I'm trying to compile Lutris as a Flatpak, as described in the Readme. But the flatpak-builder command always results in this error:

$ flatpak-builder --repo=lutris --force-clean --install-deps-from=flathub-beta build-dir net.lutris.Lutris.yml
Dependency Sdk: org.gnome.Sdk 43
Installing org.gnome.Sdk/x86_64/43 from flathub-beta
error: Nothing matches org.gnome.Sdk in remote flathub-beta
Error installing deps: running `flatpak --system install -y --noninteractive flathub-beta org.gnome.Sdk/x86_64/43`: Child process exited with code 1

I've checked that the flathub-beta repo is available and org.gnome.Sdk package can be found:

$ flatpak remote-list
Name         Options
flathub      system
flathub-beta system

$ flatpak search org.gnome.Sdk

But the error persists. Any ideas how to fix it? I'm on Ubuntu 22.04 and using Flatpak 1.12.7 from the Ubuntu repository.

you need GNOME sdk 42 (for building the stable branch) or 43 for building the beta branch, both from flathub (no flathub-beta).

Thx @A6GibKm. I've changed the command from the Readme to this one

flatpak-builder --repo=lutris --force-clean --install-deps-from=flathub build-dir net.lutris.Lutris.yml 

and now it works! I was pretty sure that I had already tried the command with the flathub repo, but apparently I didn't. Anyway, it should also be fixed in the official Readme...

Unfortunately, another error occurred during the build process:

Downloading https://mesa.freedesktop.org/archive/glu/glu-9.0.2.tar.xz

I can download that file with wget just fine, but it keeps failing during the build process...

I worked around that bug by downloading the file manually and copying it into the appropriate folder below .flatpak-builder/downloads/.

After that, I had to use the same workaround for this one:

Downloading https://mesa.freedesktop.org/archive/demos/mesa-demos-8.4.0.tar.bz2

Failed to download sources: module mesa-demos: server certificate verification failed. CAfile: none CRLfile: none

I am by no means a flatpak expert, but it looks like flatpak-builder is missing some certificates (or can't access the ones on my system). I thought that maybe there's a ca-certificates flatpak that can be installed, but I found none, so I currently don't know how to fix it properly...
