[Dune] website git errors

[Christian Engwer]

Dear all,

I cleanup the layout and think we should be able to go public, once
the content is updated, but...

git doesn't want me to push the changes:

Git LFS: (0 of 1 files) 0 B / 345 B
exit status 1
error: failed to push some refs to 'ssh://git@gitlab.dune-project.org:22022/infrastructure/dune-website'

this error is not very expressive and I have no clue what to do. Can
someone shed some light? I guess it has somthing to do with git
wanting me to put some of the files into LFS?! I am a bit disapointed
that things are turning out to be more complicated than anticipated.
Am I really expected to move a 300 byte png into _large_ file storage?
