Meld installed via GNOME Nightly repo is still pre-gtk4 port.
Yeah the main branch hasn’t properly passed since the GTK 4 merge because the macOS builds are failing; they haven’t been ported to GTK 4 yet. Possibly I’ll look at marking them allowed-to-fail for the meantime so that the flatpaks get published.
Error installing bundle: GPG verification enabled, but no signatures found (use gpg-verify=false in remote config to disable)
This isn’t familiar to me I’m sorry. Possibly the signing happens as part of the publish step instead of during the flatpak build?
