Arch Linux

Summary and Info:

I'm not sure if HTTP/2 is the symptom or the cause of the issue. But when talking with mirrors publishing over HTTP/2 on TLS (443) pacman reports an error:

HTTP/2 stream 0 was not closed cleanly before end of the underlying stream

This occurs for each repository, however which repository and if there is an error at all is random.

# pacman -Syu
[...]
error: failed retrieving file 'extra.db' from mirror.archlinux.no :
error: failed retrieving file 'multilib-testing.db' from mirror.archlinux.no : HTTP/2 stream 0 was not closed cleanly before end of the underlying stream

# pacman -Syu
[...]
error: failed retrieving file 'community-testing.db' from mirror.archlinux.no : HTTP/2 stream 0 was not closed cleanly before end of the underlying stream
error: failed retrieving file 'multilib.db' from mirror.archlinux.no : HTTP/2 stream 0 was not closed cleanly before end of the underlying stream

Note that the mirrors where reported as "up to date" before the error.

This error disappears when you select a mirror without HTTP/2 it seems.

Steps to Reproduce:

* Use a HTTP/2 mirror

* Use `pacman -Syu`.


Note it seems to be racey and it's not guaranteed that just using a HTTP/2 enabled mirror produces an error. Allan tried :)

Medium severity as it *seems* like it doesn't affect any upgrade functionality. It's just an error.
