Usually, git URLs starting with "http://" or "https://" will not work
well with flux, because they require the user to supply credentials
interactively. If possible, use an SSH URL (starting with "ssh://", or
of the form "user@host:path/to/repo").

This failure may be due to the SSH (deploy) key used by the daemon not
having write permission. You can see the key used, with

In GitHub, please check via the repository settings that the deploy
key is "Read/write". You can cross-check the fingerprint with that
given by

    fluxctl identity --fingerprint

If the key is present but read-only, you will need to delete it and
create a new deploy key. To create a new one, use

There was a problem with committing changes and pushing to the git

If this has worked before, it most likely means a fast-forward push
was not possible. It is safe to try again.

If it has not worked before, this probably means that the repository
exists but the SSH (deploy) key provided doesn't have write
permission.

In GitHub, please check via the repository settings that the deploy
key is "Read/write". You can cross-check the fingerprint with that
given by

    fluxctl identity

If the key is present but read-only, you will need to delete it and
create a new deploy key. To create a new one, use

    fluxctl identity --regenerate

The public key this outputs can then be given to GitHub; make sure you
check the box to allow write access.
