It appears that there is still no release available yet for for Ubuntu 22.10.

I get the same error under Kubuntu 23.04.

I’m not sure how to resolve the issue with ppa:haxe/releases, but I ended up removing that repository and just installing from universe (default).

Removes the problem PPA:

sudo add-apt-repository -r ppa:haxe/releases

Then install Haxe from universe:

sudo apt-get update
sudo apt-get install haxe -y
mkdir ~/haxelib && haxelib setup ~/haxelib
