Fatal: 'upstream/gh-pages' is not a commit and a branch 'gh-pages' cannot be created from it




In a new, still unregistered, package I am running into above error when trying to publish documentation. This is, amongst other things, an exercise using Literate.jl.

I tried it a couple of times, including deleting the existing gh-pages branches a few times (like in below trace). I’ve used the Documenter v0.20 in a couple of other packages without problems, but in those cases existing gh-pages branches existed. I did also refresh the deploy key and DOCUMENTER_KEY a few times.

Has anyone come across this issue?

Solved: Needed to switch the settings to build from gh-pages instead of from doc/…
