error: The permission of the setuid helper is not correct

[neoedmund]

I make a fresh install from building source from github, then
flatpak --installations
returns /usr/local/var/lib/flatpak
(this dir not exists)
then try with flatpak -v repair

F: Calling system helper: EnsureRepo
error: The permission of the setuid helper is not correct

so , what is this error exactly means , what program is missing setuid?

[neoedmund]

After I do repair and install all by root user.
flatpak run com.valvesoftware.Steam

Failed to start proxy for unix:path=/var/run/dbus/system_bus_socket: Error binding to address (GUnixSocketAddress): Address already in use

Sounds like an issue with the D-Bus tools in your base Operating System.

1. If you use the configure option --localstatedir=/var when compiling, Flatpak should use the normal path /var/lib/flatpak for the system installation.
2. Generally creating the /var/lib/flatpak directory is done by the package manager (rpm/deb) at package install time, but Flatpak can also do it, that's what the EnsureRepo call below is about.

In the future if you're looking for help with a custom compiled Flatpak, it's best to provide all the commands you used to compile it, and your base OS version. It's also probably best to use the mailing list or chat room (linked in the README) rather than the bug tracker.

Unfortunately we don't have the resources to do support here.

Thank you . the command chmod u+s /usr/lib/dbus-1.0/dbus-daemon-launch-helper mentioned in to post fix the problem instantly. It's really something should be put into FAQ.

@neoedmund I appreciate you posting this -- in a completely unrelated scenario, I was running into the same issue about "The permission of the setuid helper is not correct" but for Setroubleshootd.

It was the same solution -- the SETUID bit had gotten removed from the dbus-daemon-launch-helper, in my case at /usr/libexec/dbus-1/dbus-daemon-launch-helper.

There was essentially nothing online about this but your comment helped tremendously!
