Github Pages: Unexpected Content Error on Push

[will]

I have a theme I'm running at github,
https://github.com/willrimmer/rimmercloud
It works correctly there.
https://willrimmer.github.io/rimmercloud/

When I clone the repo locally, set the GitHub pages app as an upstream, and try to push, I get an "Unexpected Content" error in GitKraken.


Error in git after running $ git push page master

Thoughts?

@will Looks like a packaging bug. I can reproduce the error, looking into it.

[will]

@girish Any update on this? Its a show stopper for my page deployment.

[girish]

@will Forgot to update on this one. The issue is related to the use of jekyll 4 (in the gemfile). Are you able to reduce usage to jekyll 3? I think it should work after that.

I will look into updating the app to support Jekyll 4. (it seems one cannot install jekyll 3 and 4 side by side?). Or maybe it's possible with some rbenv trick.

[will]

@girish No clue, I stole this theme off of a "Easy Jekyll themes site"

[will]

@girish Shouldn't the GitHub pages app be using the latest versions of Jekyll that github pages uses to maintain compatability?

[girish]

@will Initially, I thought this was about adding Jekyll 4 support but turns out it's not.

Essentially, github-pages is a gem which pins the jekyll version to 3.8.5 - https://pages.github.com/versions/ and https://rubygems.org/gems/github-pages . Now the jekyll project has released a v4. The github pages does not actually support Jekyll 4 - See https://github.com/github/pages-gem/issues/651 .

I was able to deploy your site by simply removing Gemfile before I did a jekyll build but I am not sure if this is the correct fix. But I am getting closer to the correct fix.

[girish]

@will I pushed a new version now which I think should fix your issue. Can you confirm?

I had dig into ruby madness to see if the fix was correct. https://git.cloudron.io/cloudron/githubpages-app/-/issues/1 for the curious.

@girish Updated. Will confirm and report back.
Thank you for diving through madness for the fix

@girish It worked! Need to change some of the jekyll code around to transition from github to this, but looks good!
