Any further information on this issue yet?
I was running 5.0.3 and newest wordpress version I ran into trouble downloading certain files. WordPress was not reporting that 5.0.4. was available, so after reading on this forum that 5.0.4 was available I manually installed it. Downloads are working again.
wp-cli is still reporting same error messages as above.
But with no indication that a new version is available for download, staying up to date with the most current version is difficult.
