Cannot merge PR, and git sync stopped working

[Thomas Stüfe]

Hi,

I am trying to merge one of my PRs (https://github.com/openjdk/jdk/pull/2687),
but am suddenly denied write access on Github for the OpenJDK repository.

Possibly related: git sync stopped working for me. One one box it now asks
me to manually add the source repo, or to maintain an upstream remote. On
another, freshly installed box it now wants the github user name and
password.

Login to github via ssh works fine. 2FA works fine. Manually updating my
personal fork works too. Skara tools are up to date. Happens with the
latest git (2.31).

What am I doing wrong?

Thanks!

Thomas
