Latest nightly Could not find file 'jellyfin-web/index.html'

the latest nightly install gives the error

Could not find file 'jellyfin-web/index.html'.

i just tested by downgrading and the error is gone.

Yes, this is a build error that we are fixing. We just separated -web from being a submodule ti a build dependency.

Just to be sure, what platform is this on?

i figured as much
ubuntu 18
